Chapter 2, Problem 9P

Interpretation Introduction

(a)

Interpretation:

The formula of compound in which the combining ratios are as follows:

Sodium: hydrogen: carbon: oxygen, 1:1:1:3.

Concept Introduction:

The substance having similar atom is called an element. When two or more elements combined together chemically they form a pure substance called a compound. But in case of mixture, it is formed when two substances joined together without any chemical bonding. Example of compound is H₂ O, and example of element is N, example of mixture is mixture of sand and sugar.

Interpretation Introduction

(b)

Interpretation:

The formula of compound in which the combining ratios are as follows:

Carbon: hydrogen: oxygen, 2:6:1.

Concept Introduction:
