    The answer is 6. On the left side of the equation, there are three molecules of hydrogen gas (H2), which each contain 2 hydrogen atoms for a total of 6 hydrogen atoms. On the right side of the equation, there are 2 molecules of ammonia (NH3), which each contain 3 hydrogen atoms for a total of 6 hydrogen atoms. Therefore, the total number of hydrogen atoms present on both sides of the equation is 6.
