Question

Classify the reactions
A. C3H8 + O2(g) = CO2(g) + H2O(g)
B. Cs(s) + S8(s) = Cs2S(s)
C. nickel(III) nitrate + calcium = calcium nitrate + nickel

Classify as 1.Formation reaction
2.decomposition
3.single replacement
4.hydrocarbon combustion

Answer 1

Have you tried this problem yourself first?

Answer 2

Formation Reactions happen when you're taking reactants and forming new products.
Decomposition reactions occur when you take a single reactant and separate it into two or more species.
Single replacement reactions happen when you switch the anion paired with a certain cation.
Hydrocarbon Combustion or "Combustion" reactions occur when you take a Hydrocarbon (CxHyOz) and Oxygen (O2) to form Carbon Dioxide (CO2) and Water (H2O)
