Question

One molecule of a carbon monoxide contains 1 carbon atom and 1 oxygen atom. Which of these is the chemical formula for 4 molecules of carbon monoxide? A.) CO4 B.) 4CO C.)CO4 D.)C4O4

Answer 1

The answer is B. 4CO

The coefficient 4 represents there are 4 molecules of CO. And the formula shows there's only one Carbon atom and one Oxygen atom

Answer 2

b. 4CO

Step-by-step explanation:

One molecule of carbon monoxide contains 1 carbon atom and 1 oxygen atom. So, the chemical formula of carbon monoxide will be CO.

Each molecule of carbon dioxide will have the same molecular formula.

No. of atoms as a subscript following the symbol represents the number of atoms in that compound or molecule.

Whereas number written in the front of compound represents the number of molecule of that compound.

Take an example of 2H and
`H_2`

2H represents the two atoms of H in which two H atoms are not chemically bonded. Whereas
`H_2` represents a molecule of diatomic hydrogen in which two H atoms are bonded.

Therefore, chemical formula of 4 molecules of carbon monooxide will be 4CO
