What is produced when silicon dioxide reacts with calcium oxide?

When silicon dioxide reacts with calcium oxide, the product formed is calcium silicate. This reaction can be understood in the context of both the properties of the reactants and the nature of the reaction itself.

Silicon dioxide (SiO2) is a compound commonly found in nature as quartz and is known for its robust and stable structure. Calcium oxide (CaO), also known as quicklime, is a basic oxide that reacts with acids and some amphoteric oxides to form silicates. When these two substances are combined under high temperature, a chemical reaction occurs that leads to the formation of calcium silicate (CaSiO3). This compound is significant in various industrial applications, including the production of cement and glass.

The formation of calcium silicate is a result of the combination of one silicon atom from silicon dioxide with calcium from calcium oxide, where the silicon and oxygen from SiO2 form silicate structures upon interaction with calcium ions from CaO. This characteristic solid product has applications in construction and materials science.

The incorrect options do not represent the reaction that occurs between silicon dioxide and calcium oxide. Calcium carbonate typically forms from the reaction of carbon dioxide with calcium compounds, not with silicon dioxide. Carbon dioxide and carbon monoxide are gases that do not
