Answer:
b. 4CO
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 [tex]H_2[/tex]
2H represents the two atoms of H in which two H atoms are not chemically bonded. Whereas [tex]H_2[/tex] 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
