Identify the type of reaction represented by each equation. a: h2 + cl2 → 2hcl b: ch4 + 2o2 → co2 + 2h2o equation a represents a reaction, and equation b represents reaction. choices for both blanks combustion decombustion synthesis double displacement single displacement choose one for each blank there are some notes and examples in the images my opinions are 1. 2blank--combustion tell me if im correct 16pionts

Answer : Equation A represents a synthesis reaction, and equation B represents a combustion reaction.

Explanation :

A :

Equation A is a synthesis reaction in which the two reactants combine to form a single product.

B :

Equation B is a combustion reaction in which the a hydrocarbon react with an oxygen to give carbon dioxide and water a s a product.

Hence, the equation A represents a synthesis reaction, and equation B represents a combustion reaction.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
