Question

Part A Which of the following statements about chemical formulas is FALSE? Which of the following statements about chemical formulas is FALSE? The subscripts represent the relative mass of each type of atom in the compound. Different compounds made of the same elements have different subscripts. The subscripts represent the relative number of each type of atom in the compound. The subscripts do not change for a given compound. All of the statements are true.

Answer 1

Answer: Option (a) is the correct answer.

Explanation:

Subscript present in chemical formula of a compound represents the number of atoms of the element actually present in it.  

For example, in $C_{7}H_{7}NO_{2}$ the subscripts present in it are 7, 7, 1, and 2.

A subscript is not responsible for determining the relative mass of each type of an atom because a subscript simply represents the number of atoms of each type of an element participating or combining with other atoms of a compound.

Thus, we can conclude that the statement subscripts represent the relative mass of each type of atom in the compound, is false.
