From the given reaction, we can deduce that:

1. Silica is acidic: This is because it is reacting with a base (calcium oxide) to form a salt (calcium silicate). This is a characteristic of an acid-base reaction.

2. Calcium oxide is not thermally decomposed in this reaction. Thermal decomposition would involve breaking down calcium oxide into simpler substances by heating, which is not happening here.

3. Limestone is basic: Limestone primarily consists of calcium carbonate, which when heated forms calcium oxide and carbon dioxide. Calcium oxide is a basic oxide because it reacts with an acid (silica in this case) to form a salt.

4. Calcium silicate is not necessarily basic. It is a salt formed from the reaction of an acid and a base. Its acidic or basic nature would depend on the relative strengths of the original acid and base. In this case, we cannot deduce its nature from the given information.
