1.) When two or more substances combine in chemically in ways that make a new substance. 

# data[].attributes.body
Yes, it is possible to turn old things into new ones

# data[].attributes.body
Because it was an exothermic reaction.

3. Yes, it is possible. They can be combined chemically. 

# data[].attributes.body
A mixture

# data[].attributes.body
Yes

# data[].attributes.body
You can combine things chemically which then will produce a new substance.

# data[].attributes.body
If they chemicaly react, a new substance, if not a mixture

# data[].attributes.body
No

# data[].attributes.body
yes you can turn old stuff in to new stuff.

# data[].attributes.body
look at the proprieties from before and after

# data[].attributes.body
New substances don't always come from old substances because you can separate the new substance.

# data[].attributes.body
Because there was some type of reaction that happened

# data[].attributes.body
There was a chemical reaction that happened

# data[].attributes.body
baking is a chemical reation that people do daily

# data[].attributes.body
Yes! It is completely possible to change things back to the original substances from their changed state.
