Which is a correctly balanced equation for a reaction between hydrogen gas and oxygen gas? A. 2H_(2)(g)+2O_(2)(g)arrow H_(2)O(g)+heat B. 2H_(2)(g)+O_(2)(g)arrow 2H_(2)O(g)+heat C. H_(2)(g)+O_(2)(g)arrow H_(2)O(g)+heat D. H_(2)(g)+O_(2)(g)arrow 2H_(2)O(g)+heat

The correct answer is B. Explanation:The balanced chemical equation for the reaction between hydrogen gas (H2) and oxygen gas (O2) to form water (H2O) is: This equation is balanced because the number of atoms of each element is the same on both sides of the equation. Specifically:- There are 4 hydrogen atoms on both sides.- There are 2 oxygen atoms on both sides.The other options are not correctly balanced:A. is not balanced, as there are 4 oxygen atoms on the left side and only 1 on the right side.C. is not balanced, as there are 2 hydrogen atoms on the left side and only 1 on the right side.D. is not balanced, as there are 2 hydrogen atoms on the left side and 4 on the right side.Therefore, the correct answer is B. .
