egg yolk and honey are mixtures, the rest pure substances

define pure substance, cause the the first and third are molecules while the second is an element

>>1863468

Good job,

Next question,

Digesting food is an example of

>a physical change.
>a chemical change.
>a change of state.
>buoyancy.

*choke* IS THIS FUCKING 3RD GRADE SCIENCE? GO TO BED, JIMMY!

>>1863492
ITS A CHEMICAL CHANGE

CHEMICAL


THE ANSWER IS

CEHMICAL CHANGE

>>1863492

buoyancy.

FUCK SCIENCE, NIGGER.

>>1863492
chemical

>>1863500

trick question, its both, physical and chemical.

physical:chewing food, making it into bolus, squeezing it through the esophagus.

chemical: everything related to enzymes and change of composition, or breaking down stuff.

egg yolks and honey can both be impure according to islam. c3h8o may or may not be, depending on if it is an alcohol like propanol (impure) or an ether (pure) therefore i would say 1, 2 and 3 are pure, while 4 and 5 are impure.

here come an easy question,

A molecule is the smallest unit of a substance that retains the ____ of that substance.

FUCKING BUYANCY >>1863542

>>1863435
stop trying to get /sci/ to do your homework.

Put the text of the questions into google and you will get the answers.
Sometimes you even get the answer key your teacher took the questions from.

Also: If you do your assignments this way you're still going to be fucked on the tests if you don't get the concepts.
Tests are weighted more usually so you will still fail even if you get away with cheating the assignments.

>>1863542

hallowed knowledge

Last question was a bit to easy. how about this,

Tooth fillings are often made of gold or porcelain because those materials are NOT ____.

>a substance that contains only one kind of matter; elements and compounds are pure substances
>n chemistry, a mixture is when two or more different substances are mixed together but not combined chemically.

So in theory they are all pure substances but none are mixtures. Chocolate milk is a mixture, Honey complex carb and eggyolk is a organic structure. Yet again im a business major

>>1863579
cheap

>>1863579
radioactive!

>>1863579
Thats a good fucking question.

>>1863492

Ding, Ding, Ding!

Correct!

Explain why baking is a chemical change

((Another easy question))

>>1863628
because you take some things and turn them into another

>>1863628

Trick question - it's actually a physical change since all baking really is is adding heat

>>1863643
yes, and also you must use your arms to mix the stuff, so that's physical too

Sorry >>1863643

According to this answer key i have here, its a chemical change. besides, can you UN-bake a cake?

New Question,

Grinding wheat into flour is an example of a(n) _____ change.

>>1863666

fuck you, I've baked cookies and then melted and froze them back into cookie dough before

>>1863666
state change, from (s)olid, to (p)owder

>>1863673

Now is that anyway to talk to the game master? the games have only begun, if your already in rage by now then i want to see the look on your face when i ask my next question.

>>1863666
It's chemical because adding heat causes some ingredients to oxidize and others to change form and still others to bond with mixed ingredients.

example. sugar caramelizing and meat browning.

>be in Turkey (middle east)
>learn those shit on 6th grade
HAHA oh wow

>>1863681

Correct!

heres a math question for a bit of variety.

5g+11-9=8g+4+2g

>>1863708
-2/5=g

>>1863706
>Post in an english board making fun of the simplicity in this thread. Cannot use simple english properly.

Hahaha, oh wow.

>>1863720

Correct!

Next question,

If you have a fox, a chicken, and a bag of feed that you have to take across a river, and you can only carry one at a time, how would you do it without the fox eating the chicken or chicken eating the feed?

>>1863766
>>1863766
>implying i didnt do it by purpose
Nice try,euroarabia!

>>1863781
EAT ALL OF THEM FIRST

>>1863781
take the chicken, then the fox, then take the chicken back, take the feed, then the chicken last

>>1863790
this

>>1863790

Correct!

explain the scientific theory of evolution in 10 words or less.

>>1863809

Monkeys had retarded babies which somehow turned into humans.

>>1863809
survival of the fittest

OR

Natural selection

>>1863809
Organisms either die or adapt to their environment to survive.

>>1863809

>>1863818 is funnest
>>1863821 is the most correct

Explain how time travel into the future would be possible, according to the theory's of Steven Hawking, without using any words that have 12 letters or more.

>>1863836
I have no idea, but i think it has something to do with going through black holes that allow traveling vast distances in a smaller time frame.

Boy, I sure do love High School Chemistry!

>>1863847

Thats one of his theories, which I'm sure was proven wrong, if I'm correct.

>>1863836
The speed of light is constant across all frames of reference but time is not.
As you approach the speed of light, time slows down for you but remains the same for the world around you.
In effect, not time passes around you that passes for you.
When you slow down again you will be in the future compared to the time progression recorded by you.

>>1863856
yeah i dont know, only saw one show once and thats about all i remember, haha

>>1863836
HI, this message is from the past. to bring it here, I first wrote it and used my time machine to evacuate organic byproducs before hitting submit. That's how I travelled here from the past.

>>1863863
Not sure if this is attributed to hawking or not tho, it's really just a consequence of special relativity.
Demonstrable too, just read about an experiment that showed there is a measurable time difference even across as little vertical distance as a flight of stairs.

>>1863836
Then what is the actual correct answer?

Captcha just said it best: growage family

>>1863875
ie - he took a piss before hitting submit? lol

>>1863863

Correct!

Heres one for the trolls.

If i have a stick that is 1 light year long and i have a friend thats 1 light year away from me ((Chilling in space with his "I don't need to breath" powers)) and I poke him with the stick, will he feel the stick poke him before he sees it poke him?

>>1863863
the opposite would also be true. as you slow down, time moves faster for you which is why, sitting still in front of a computer, time seems to go faster.

>>1863884
THEN WHY DOES TIME FLY WHEN YOU'RE HAVING FUN???

>>1863882
yes, but he would also disintegrate from the force

>>1863882
He will see it first of course.
Light travels faster than nerve impulses.
Same case as if I poked you in the arm with my finger.
The difference is so minute though that he will not notice which happened first.

Q. Why is OP a faggot
A. Because he fucks men

Other possible answers include, he is underage b&, retarded, and cant do his homework

You must quote this post if you saw C3PO before C3H8O

>>1863884
only relative to a fast moving body
>>1863892
this is a matter of perception, time SEEMS to fly when having fun because you do not pay attention to it.

>>1863898
u mad?

ITT: Science trivia game.
I'm okay with this.

>>1863901
lol starcraft

>>1863898

Riddle me this batman,

why is faggot a OP?

For everyone else.

If im on a space shit thats nearly going the speed of light, then if I walk forward to the bathroom because i need to take a piss, will I go even slower in time and will everyone around me look like there going at the speed of super fast as they see me as going as if i was in a slow mo shot of a movie.

>>1863902
Is there a form of perception in which I can SEEM to go back in time?

>>1863915
Huh? So you want to piss on your space shit?

is the effect of speed on time direct or exponential?

>>1863920
yeah, in my perception a lot of people seem to go back in time, at least in ther "choice" of clothing

>>1863882
A light year is a measure of distance is it not? not time?
Correct me if im wrong...

So that means he should see it first, unless of course he is not facing the direction of said stick, or asleep or something like that.

>>1863926

replace the word shit with the word ship.

Better way of saying th question. If im on a bus in space thats going near the speed of light ((like 99.9999999%)) then if i get up and walk up the hallway of th bus, then will I slow down and look like im in a slow-mo shot of an action film, or go the same speed as everyone on the bus sitting down.

>>1863935
I lol'd
So what's /fa/ doing on /sci/?

>>1863915
no that wont happen because 'space shit' does not exist, the speed of light is not achievable. If it was, there would be no difference because all the light or whatever within the space "ship" would be going the same speed as all the occupants - so it would just look like normal walking

>>1863941
im sure your speed plus the speed of the bus isnt THAT much closer to the speed of light, so when the bus is going 99.9999999999999999999, youll be going 99.99999999999999999991

not much of a difference

>>1863941
I think you're confused.
"the" is spelled T-H-E
You keep typing "th"

>>1863942
not /fa/, but the irony is that since 70's clothing is all the rage nowdays, in THEIR perception they seem to be moving faster than their surroundings. I also recently raeg'd at a some hag on TV dismissing WINE GRAPES as "so last year". because taste sensations are trendy.

>>1863915
Time for you will slow slightly relative to those around you who are not walking and slower still for those who are not traveling and walking on space shit near the speed of light.
Those around you who are also traveling on the space shit will see you just as you would see someone walking across shit not traveling near the speed of light.
This is because from your frame of reference to theirs you are only traveling at foot speed.
From your frame of reference to those not on space shit traveling near the speed of light you are traveling at foot speed plus the speed of space shit traveling near the speed of light.

>>1863962

My e key is messed up. and will sometimes do that.

New question?

If Shara has 2 apples and James has 3 apples, then if James gives Shara one of his apples, dose that mean James has a crush on Shara? P.S. Shara is a trap. Dose that make James gay?

>>1863979

you are not red trainer

go away

>>1863934
Without confirmation, I'd say it is direct.
Time must slow evenly with added speed in order to maintain the speed of light across all frames of reference.

>>1863979
no you fool, just means he gave 'him' an apple without knowing its a 'him'

If jack and Jill went up the hill to fetch a pail of water, and jack fell down on his crown, then how badly hurt is jack?

The hill was 25 feet high and jack made it to the top before falling all the way down.

>>1863979
is James OP? if so, yes, and yes.

>>1863979
Answer is subjective to societal norms.
James' sexual preference is his choice, independent of other choices he makes.
ie - his choice to give apples to others or not does not limit the number of options he has for sexual preference.

>>1864000
well he can't exactly fall if it is a hill, unless there is a cliff or an edge where he will not make contact with said hill, then that would be falling and he would probably be dead or concussion. If its a hill with all slopes, then he would slide/tumble/etc down not fall. So he wouldn't really be harmed unless he built up too much momentum and then smacked his crown near the bottom.

>>1864016
>implying crown is his head as well

>>1864012

A true man of science right here. Give himm a medal for not calling OP a faggot and leaving the thread.

Only a true man of science will attempt to find a logical answer for any question, no matter how retarded.

>>1864016
Also I find it difficult that he would fall on his crown the whole distance, I think he would have just fell backwards or something, so he wouldnt really be injured unless he fell onto a rock or something nearby.

>>1864000
Not enough information.
Must also know the slope of the hill, resistance of the material the hill is made of, if the part he fell off of was actually a cliff or not, and which way he rolled horizontally or head over feet.

>>1864024
Thank you op.
The wife hates me sometimes because of shit like this:

lol

If I have A portal gun from portal and I put a box in a infinitive loop where the bow will fall from the sealing into the portal on the ground and I wait for 1 day for the box to gain enough momentum and then put a portal on the ground in a park somewhere, would the box beable to make it into space?

>>1864039
no because there is only so much speed that the box could posses with wind resistance and weight just using the pull of the earths gravity.

>>1864039

re-wording this question, If I do this,

http://www.youtube.com/watch?v=3L-rrkyvApU

25 seconds in ot 45 seconds in

but i left the box for 3 days and tried to launch the box into space, would it make it?

>>1864039
Terminal velocity is MUCH less than the escape velocity required to leave earth's atmosphere.

>>1864044
So it would reach its max speed and not increase any further, so leaving it for longer won't change anything.

If A = B then B = A what does that make B?

>>1864055
Correct, the box would stop accelerating when it reaches terminal velocity, which is less than escape velocity.

>>1864073
B = B of course.

>>1864078
B doesn't exist

What if the box weighed 1 million US pounds at surface level? Would it at least reach lower atmosphere?

>>1864108
A = 10 = B then B = 10 = A
A and B are both equal to 10 and both exist. They are merely the same.

>>1864111
How high it goes is a function of weight to surface area in this case.
If the box is small but weighs enough it can reach a terminal velocity which would be greater than or equal to escape velocity.

I have a question for you Red Trainer. Can you see why kids love Cinnamon Toast Crunch?
