Answer:

C. CaCO₃  

Explanation:

One formula unit contains the elements calcium, carbon, and oxygen. Start by writing the symbol of the elements:

CaCO

We indicate the number of atoms of each element by writing the number as a subscript following the symbol.

One formula unit contains one atom of Ca, one of C, and three of O, so the formula becomes

Ca₁C₁O₃

Finally, we do not write one as a subscript in a formula. If there is no subscript, we automatically assume that it is one. Thus, the correct formula is

CaCO₃

D. The total number of gas molecules will decrease.

Explanation:

According to Le Chatelier's principle, an increase in pressure in a system involving gases will cause the total number of gas molecules to decrease.

Le Chatelier's principle states that "if any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

In a reaction involving gases, a change in pressure affects only reactions in a gaseous phase.

An increase in pressure on an equilibrium system will shift the position of the equilibrium to the side having smaller volume and vice versa.
