Types of chemical reactions

During class we recalled the chemical reactions that we learned last year in science 10: Syntheis, decomposition and single replacement.

Synthesis: This is when one compound combines with another compound to create a more complicated one.  The formula would be: Compound A + Compound B = Compound C

8 Fe + S₈ ---> 8 FeS

Decomposition: Opposite of a synthesis reaction.  A complicated compound breaks down into simpler ones. The formula would be: Complicated C = Compound A + Compound B

2 H₂O ---> 2 H₂ + O₂

Single Replacement: This is when one element trades places with element in a compound: The formula would be A + BC = AC + B OR A +BC = BC + A

Mg + 2 H₂O ---> Mg(OH)₂ + H₂
