Compounds which on dissolving in water gets completely dissociates into its ions are known as strong electrolytes whereas compounds which on dissolving in water gets partially dissociates into its ions are known as weak electrolytes.
Substances which gives solution on dissolving in water and do not dissociates into ions also does not conduct electric current are known as nonelectrolyte.
- Hydrochloric acid,
On adding (strong acid) in water, it will completely dissociates into ions (
and
) and thus, it is a strong electrolyte.
- Sodium hydroxide,
On adding (strong base) in water, it will completely dissociates into ions (
and
) and thus, it is a strong electrolyte.
- Formic acid,
On adding (weak acid) in water, it will partially dissociates into ions (
and
) and thus, it is a weak electrolyte.
- Methyl amine,
On adding (weak base) in water, it will partially dissociates into ions (
and
) and thus, it is a weak electrolyte.
- Potassium chloride,
On adding in water, it will completely dissociates into ions (
and
) and thus, it is a strong electrolyte.
- Ethanol,
On adding in water, it will not dissociates into ions and thus, it is a nonelectrolyte.
- Sucrose,
On adding in water, it will not dissociates into ions and thus, it is a nonelectrolyte.
Answer:
The right solution is "-602.69 KJ heat".
Explanation:
According to the question,
The 100.0 g of carbon dioxide:
=
=
We know that 16 moles of formation associates with -11018 kJ of heat, then
0.8747 moles formation associates with,
=
=
=
