1.)Why is mass conserved in a chemical change?
a.)The energy used in the chemical reaction burns up the extra matter.
b.)The compounds are still exactly the same, they just look different.
c.)The atoms are still there, they are just rearranged to form new compounds.
d.)The new matter that is formed takes up the same volume as the original matter.
2.)What is always conserved in a chemical reaction?
a.)Mass is always conserved in a reaction.
b.)Energy is always conserved in a reaction.
c.)Mass and energy are both conserved.
d.)Nothing is always conserved in a reaction.
