What do you know about a chemical compound by looking at its chemical formula? the properties of the molecules in the compound how the compound reacts with other compounds how many molecules are in a sample the number and kinds of atoms in the compound

Option (d) is the correct answer.

Explanation:

A chemical formula is a symbolic representation of a compound or molecule that shown how many atoms of an element are present. Also, it helps in known the kind of atoms present in a compound.

For example, chemical formula of calcium chloride is .

So, it shows that there are two chlorine atoms and one calcium atom.

Also, it shows that bonding is taking place between a metal and a non-metal.

Thus, we can conclude that we get to know about the number and kinds of atoms in the compound by looking at its chemical formula.
