Answer 1

2naoh+sio2 =na2sio3+h2o

Answer 2

Identification of Silicon Oxide as an Acidic Oxide

To determine the classification of silicon oxide as an acidic oxide, we can examine its reaction with water. Acidic oxides react with water to form acids. Let's write the equation for the reaction:

SiO2 + H2O → H2SiO3

In this reaction, silicon dioxide (SiO2) reacts with water (H2O) to form silicic acid (H2SiO3).

Therefore, the reaction of silicon oxide (SiO2) with water (H2O) demonstrates its classification as an acidic oxide.
