Sure, let's go through each equation step-by-step to identify the type of reaction.

Equation A: [tex]\( H_2 + Cl_2 \rightarrow 2 HCl \)[/tex]

1. Reactants: Hydrogen ([tex]\( H_2 \)[/tex]) and Chlorine ([tex]\( Cl_2 \)[/tex]).
2. Product: Hydrogen Chloride ([tex]\( HCl \)[/tex]).
3. Type of Reaction: This reaction involves two reactants, hydrogen and chlorine, combining to form a single product, hydrogen chloride. This type of reaction is known as a synthesis reaction because it synthesizes a new compound from simpler substances.

Equation B: [tex]\( CH_4 + 2 O_2 \rightarrow CO_2 + 2 H_2O \)[/tex]

1. Reactants: Methane ([tex]\( CH_4 \)[/tex]) and Oxygen ([tex]\( O_2 \)[/tex]).
2. Products: Carbon Dioxide ([tex]\( CO_2 \)[/tex]) and Water ([tex]\( H_2O \)[/tex]).
3. Type of Reaction: This reaction involves a hydrocarbon (methane) reacting with oxygen, resulting in the production of CO_2 and H_2O. This is characteristic of a combustion reaction, where a hydrocarbon burns in the presence of oxygen to release carbon dioxide and water, typically producing heat and light in the process.

So, to fill in the blanks:

Equation A represents a synthesis reaction, and Equation B represents a combustion reaction.
