Match each element or compound with the appropriate symbol or molecular formula. Carbon dioxide CO2 carbon o oxygen Н H water с hydrogen H2O

Carbon dioxide ---> CO₂

Water > H₂O

Carbon ---> C

Oxygen > O₂

Hydrogen > H₂

Explanation:

The molecular formula of an element or compound is a formula which represents the composition of a molecule of that element or compound. It consists of the formula representing the atoms present as well as the number of atoms of each element innthe compound written as subscript innthe formula of the element or compound.

The molecular formula of the given elements and compounds are given below:

Carbon dioxide ---> CO₂

Water > H₂O

Carbon ---> C

Oxygen > O₂

Hydrogen > H₂

The molecular formula of carbon dioxide shows that in a molecule of carbon dioxide, there are two atoms of oxygen and one atom of carbon present in a molecule of carbon dioxide.

The molecular formula of water shows that are two atoms of hydrogen and one atom of oxygen present in a molecule of water.

The molecular formula of carbon shows that there are one carbon atoms in a molecule of carbon.

The molecular formula of oxygen shows that there are two oxygen atoms in a molecule of oxygen gas.

The molecular formula of hydrogen shows that there are two molecules of hydrogen in a molecule of hydrogen gas.
