5. Types of Reactions Synthesis A + B  AB (one product)
Decomposition AB  A + B (one reactant)
Single Replacement A + BC  AC + B (one element is replaced)
Double Replacement AB + CD  AD + CB (Two compounds switch partners)
Combustion A + O2  CO2 + H20 (same products every time)

11. Law of conservation of mass
Matter is never created or destroyed
Can you think of any simple examples to explain this?
Whether you agree or not thatstars light years away, made primarily of hydrogen and helium, can really be responsible for humans and other living things, the fact remains that
