To determine the mole ratios of the substances, we need to know the balanced chemical reaction of the system. The reaction between hydrazine and hydrogen peroxide yields to nitrogen and water. The balanced chemical reaction is:
N2H4 + 2H2O2 --> N2 + 4H2O
Therefore, the mole ratio between hydrazine and hydrogen peroxide is 1:2 and the mole ratio between hydrazine and water is 1:4.
Water absorbs energy D. Melting
Anything less that 7, would be a base.

Answer:
the pH of the solution expresses the concentration of hydrogen ion in the solution. By measuring the pH value of a solution helps us to define the acidity or basicity of the solution. If the pH value in the pH scale is greater than 7 then the solution is basic
