(a)
Interpretation:
It should be identified that whether the given reaction is balanced or not. If it is an unbalanced equation the equation should be balanced.
Concept introduction:
In a balanced equation the number of atoms of each element as a reactant is equal to the number of atoms of that element as a product.
Coefficient is a number placed before a formula in a chemical equation.
A balanced equation should be obeying the law of conservation of mass. Law of conservation of mass states that, the number of atoms remains constant throughout the reaction, simply it can be stated as follows, “during a

- Which of the following correctly explains why the vapor pressure of water has to be included in the calculations? Some of the liquid water evaporates into the gas, and increases the total pressure generated by the trapped gas. As the H2(g) is bubbled up the reaction solution, some of the H2(g) molecules are solubilized by water in the aqueous solution, effectively decreasing the measured pressure above. The pressure contributed by the H2(g) is greater than the measured total pressure because of the contribution of partial pressure of water vapor. The pressure exerted by the evolved H2(g) is reduced because of the co-presence of water vapor, thus Pwater vapor has to be added to Pdry gas.
