D.) reactants - 1 mole of gas, products - 0 moles of gas, Δn = -1 moles
Answer:
The answer is 'All of the above'
Explanation:
because the hydrogen ions are represented by the symbol H+, they increase the PH value of a solution if less amount is added but they decrease the PH value of a solution if a larger amount of hydrogen ions are added but still they increase the PH value, and of course, they contribute to a solution by a base.
