J.J. Thomson discovered the electron 1897
Answer: pH = 7.36. The pKa of H2PO4− is 7.21.
Explanation:
Answer:
The change of state requires energy.
Explanation:
Instead of the energy changing the temperature the heat energy is used by changing its form.

Answer:
None of the conditions will favor either the forward reaction or backward reaction , hence the answer is D
Explanation:
- The principle of chemical Equilibrium is applied here, where the concentration of the reactants or the forward reaction is same as the concentration of the products or the backward reaction.
- The equilibrium constants is also involved here, K can be in terms of pressure (Kp) or concentration (Kc) hence equilibrium constant is the ration of the concentration of the products to the concentration of the reactants raised to the power of the coefficient of the reactants and products.
- Partial pressure , total pressure and the mole fraction relationship is also applied
- The step by step explanation is as shown in the attachment below.
