What occurs in order to break the bond in a cl2 molecule? explanation .

Options for the question;

(1) Energy is absorbed.

(2) Energy is released.

(3) The molecule creates energy.

(4) The molecule destroys energy.

(1) Energy is absorbed.

Explanation:

Using the Method of elimination;

Option 1 - Energy is absorbed to break bonds. Bond-breaking is an endothermic process. This means this option is correct.

Option 2 - This option is incorrect because bond breaking is endothermic in nature. Energy is being absorbed and not released.

Option 3 and 4 - These optons are wrong because energy can neither be created nor destroyed but can change from one form to another.

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
