2.
Calculate the heat of reaction for the following process:
3 FeCl2 → Fe + 2 FeCl3,
given the following info:
Fe + 2HCl → FeCl2 + H2H
2 Fe + 6 HCI → 2 FeCl3 + 3 H2
1822
AH = -769 kJ
AH = 41822 kJ
3. Calculate the heat of reaction for the following reaction:
Fe + 2 Agri → 2 A Coru

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
