Detailed explanation-1: -Formation of water is a chemical reaction because in this reaction a new compound is formed. It is also a combination reaction because hydrogen and oxygen combine to form a single product (water). The reaction is 2H2(g)+O2(g)→2H2O(l).

Detailed explanation-2: -Answer and Explanation: The formation of water is classified as a synthesis reaction becuase it involves combining two molecules to form a single, larger molecule. The two molecules that are combined to form water are oxygen and hydrogen. The overall equation for the formation of water is: 2H2 + O2—> 2H2O.

Detailed explanation-3: -Formation of water from hydrogen and oxygen is a combination reaction because hydrogen and oxygen are combining to form single product. The reaction occurs as follows: 2H2(g)+O2(g)→2H2O(l)

Detailed explanation-4: -Synthesis reactions occur when two or more reactants combine in order to form a singular product. In this case, the 4 hydrogen atoms in the 2 hydrogen gas molecules (H2 ) combine with the 2 oxygen atoms in the 1 molecule of oxygen gas (O2 ). In doing this, only one product, water or H2O H 2 O, is formed.

Detailed explanation-5: -The formation of water from hydrogen and oxygen is a combination reaction.
