Answer:

The relationship of pH and concentration of H+ ion is pH = -lg[H+]. So the concentration of H+ is 10^(-2). And [OH-][H+]=10^(-14). pOH + pH = 14. So the right answer is A.

What happens to the volume of a gas when you double the number of moles of gas while keeping the temperature and pressure consta

Sunny_sXe [5.5K]

Answer: The volume of the gas also gets double when number of moles are doubled.

Explanation:

The relationship of number of moles and volume at constant temperature and pressure was given by Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.

The equation used to calculate number of moles is given by:

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$
