The balanced chemical reaction is written as:
<span>Zn(s) + 2HCl(aq) = ZnCl2(aq) + H2(g)
</span>
We are given the amount of the reactant zinc to be used in the reaction This amount would be the starting point for the calculation. It is as follows:
5.00 mol Zn ( 1 mol H2 / 1 mol Zn ) (2.02 g H2 / 1 mol H2 ) = 10.1 g H2
Therefore, the correct answer is the second option.
The transfer of energy that occurs when a force is applied over a distance is WORK.
