E. Explain the similarity and differencein two events, namely adding NaOHto water and adding CaO to water.​

Answer»

EXPLANATION:

NaOH you are only dissolving the material, whereas CaO REACTS to make Ca(OH)2 .

The calcium HYDROXIDE has a lower SOLUBILITY in water than NaOH and so will precipitate out.

Adding CaO to Water - A lot of heat (exothermic reaction) is produced in the reaction, which may even CAUSE the water to boil.
