Answer:
pH + pOH = 14, [H₃0⁺] [0H⁻] = 10⁻¹⁴
Explanation:
When it comes to questions involving pH, the equations used are;
[H₃0⁺] [0H⁻] = 10⁻¹⁴
This equation shows the concentration of hydroxonium ions alongside that of the hydroxide ions.
pH + pOH = 14
If the value of either the pH of the pOH is know,one can calculate the value of the other using this equation.
2MgO
This is called redox reaction. Oxygen is the oxidizing agent to receive 2 electrons from Mg.
Mg is the reducing agent to give 2 electrons to O.
Mg becomes Mg2+ and O becomes O2-. These 2 ions form an ionic structure called MgO

The new volume will be 33.5 L.
Explanation:
The kinetic theory of gases confirm that the volume occupied by gas molecules will be directly proportional to the temperature of the molecules and inversely proportional to the pressure of the molecules. We can consider the moles to be n = 1. Then, the equation for the gases will be
PV = nRT
Here, P is the pressure, V is the volume, R is the gas constant and T is the temperature.
So, P = 523 Torr, T = 7.50 °C = 7.50+273.15 = 280.65 K and the gas constant R = 62.363 Torr L mol⁻¹K⁻¹.
Thus, the new volume will be 33.5 L.
