Which of the following compounds formed between non-metals will NOT dissolve in water?Ahydrogen chlorideBsilicon(IV) oxideCcarbon dioxideDsulfur dioxide

The compound that will NOT dissolve in water is Silicon(IV) oxide (SiO2).

Here's why:

A. Hydrogen chloride (HCl) is a gas that dissolves in water to form hydrochloric acid, which is a strong acid and very soluble in water.

B. Silicon(IV) oxide (SiO2), also known as silica, is a covalent network solid and is insoluble in water.

C. Carbon dioxide (CO2) is a gas that dissolves in water to form a weak solution of carbonic acid.

D. Sulfur dioxide (SO2) is a gas that dissolves in water to form a solution of sulfurous acid.

To determine which of the compounds formed between non-metals will not dissolve in water, we need to consider their chemical properties.

A) Hydrogen chloride (HCl): This compound is a strong acid and will readily dissolve in water to form H+ and Cl- ions. Therefore, hydrogen chloride will dissolve in water.

B) Silicon(IV) oxide (SiO2): This compound is commonly known as silica or quartz. It is insoluble in water and does not dissociate into ions. Therefore, silicon(IV) oxide will not dissolve in water.

C) Carbon dioxide (CO2): This compound is a gas at room temperature and pressure. It can dissolve in water to a limited extent, forming carbonic acid (H2CO3). However, carbon dioxide itself does not dissociate into ions in water. Therefore, carbon dioxide will dissolve in water, but it does not form ions.

D) Sulfur dioxide (SO2): This compound is a gas at room temperature and pressure. It can dissolve in water to form sulfurous acid (H2SO3). Similar to carbon dioxide, sulfur dioxide does not dissociate into ions in water. Therefore, sulfur dioxide will dissolve in water, but it does not form ions.

Based on the above analysis, the compound that will NOT dissolve in water is B) silicon(IV) oxide.
