[req] Chemistry Help

Hi I need some help with chemistry..

1. If I mix 10 mL of vinegar together with ammonia water, how do I separate them again?

2. If I mix 1.0M copper (II) sulfate with ammonia water, how do I separate them again?

3. If I mix baking soda and vinegar, how do I separate them again?

I don't think it is distillation.

4. What's the chemical and physical change of a burning candle?

<s>5. What gas causes a glowing splint to burn? </s>

<s>6. What gas is produced when aluminum and NaOH pellets are mixed with water?</s>

But ish so hard.

 

Ahaha, I swear I just did this. Where do you live?

 

centrifuge? or decentrifuge?
(ya know,the spinny thingie)

 

I'm not sure if it's that since they have similar densities.

 

bump. Need answers in 2 hours.

 

7. What gas is produced when baking soda and mixed with vinegar?

carbonic acid is the answer almost 100% sure

which is also known as CARBON DIOXIDE

 

dude centrifuge has got to be the answer to 1 of those seperation questions,send me creds if you want to

 

Dude there are a bunch of ways to separate give me a second and I will have the correct answers just did this checking over my notes for the correct answers

 

ummmm........you can seperate mixtures by sifting or magnetism,send creds if that was enuff for ya

 

6. What gas is produced when aluminum and NaOH pellets are mixed with water?

I believe the answer is Sodium Hydroxide if thats what you thought I would go with it because I believe that is correct
