Chapter 2: Problem 35

What does a chemical formula represent? What is the ratio of the atoms in the following molecular formulas? (a) NO, (b) \(\mathrm{NCl}_{3}\) (c) \(\mathrm{N}_{2} \mathrm{O}_{4},\) (d) \(\mathrm{P}_{4} \mathrm{O}_{6}\)

Short Answer

Expert verified
A chemical formula represents the number and types of atoms present in a molecule. The ratio of atoms in the given formulas are - (a) NO - 1:1, (b) \(\mathrm{NCl}_{3}\) - 1:3, (c) \(\mathrm{N}_{2} \mathrm{O}_{4}\) - 1:2, (d) \(\mathrm{P}_{4} \mathrm{O}_{6}\) - 2:3.

Step by step solution

01

What Does a Chemical Formula Represent

A chemical formula represents the number and type of atoms present in a molecule of a substance.
02

Finding Ratio in (a) NO

The formula NO is composed of Nitrogen (N) and Oxygen (O). Since there are no numerical subscripts present, it means there's one atom each of Nitrogen and Oxygen. Therefore, the ratio of Nitrogen to Oxygen is 1:1.
03

Finding Ratio in (b) \(\mathrm{NCl}_{3}\)

In the formula \(\mathrm{NCl}_{3}\), there is one atom of Nitrogen and three atoms of Chlorine. Therefore, the ratio of Nitrogen to Chlorine is 1:3.
04

Finding Ratio in (c) \(\mathrm{N}_{2} \mathrm{O}_{4}\)

In the formula \(\mathrm{N}_{2} \mathrm{O}_{4}\), there are two atoms of Nitrogen and four atoms of Oxygen. Thus, the ratio of Nitrogen to Oxygen is 1:2.
05

Finding Ratio in (d) \(\mathrm{P}_{4} \mathrm{O}_{6}\)

In the formula \(\mathrm{P}_{4} \mathrm{O}_{6}\), there are four atoms of Phosphorus and six atoms of Oxygen. Hence, the ratio of Phosphorus to Oxygen is 2:3.
