Question 3.14: Determine whether each of the following equations represents...

Determine whether each of the following equations represents a combination reaction, a decomposition reaction, or a combustion reaction: (a) H₂(g) + Br₂(g) → 2HBr(g), (b) 2HCO₂H(l) + O₂(g) → 2CO₂(g) + 2H₂O(l), (c) 2KClO₃(s) → 2KCl(s) + 3O₂(g).

Strategy Look at the reactants and products in each balanced equation to see if two or more reactants combine into one product (a combination reaction), if one reactant splits into two or more products (a decomposition reaction), or if the main products formed are carbon dioxide gas and water (a combustion reaction).

Setup The equation in part (a) depicts two reactants and one product. The equation in part (b) represents a combination with O₂ of a compound containing C, H, and O to produce CO₂ and H₂O. The equation in part (c) represents two products being formed from a single reactant.
