Question

What happens when Quick lime is heated with silica.

Answer 1

Quick lime means calcium oxide CaO
Silica means SiO2.
CaO + SiO2 ---> CaSiO3
calcium silicate is formed.

Answer 2

Answer: This reaction leads to the formation of calcium silicate.

Explanation:

Quick lime is the common name for calcium oxide. The chemical formula for this is CaO. Silica is the common name for silicon dioxide. The chemical formula for this is $SiO_2$

The reaction between quick lime and silica is given by the equation:

$CaO+SiO_2\rightarrow CaSiO_3$

By Stoichiometry of the reaction:

1 mole of calcium oxide reacts with 1 mole of silicon dioxide to produce 1 mole of calcium silicate.

Hence, this reaction leads to the formation of calcium silicate.
