Question

Which can be determined using a chemical formula?
a. the elements that make up the compound
b. the substances that make up a solution
c. the pH of a solution
d. the boiling point of a compound

Answer 1

A chemical formula can be directly used to find out the elements that make up the compound. Also, since each chemical compound has a unique boiling point, that can also be determined by just knowing the chemical formula. The answers are:

a. the elements that make up the compound
d. the boiling point of a compound

Answer 2

Answer: a. the elements that make up the compound

Explanation:

Chemical formulas are the symbolic representation of the elements contained in a compound along with their relative proportions.

For example: The chemical formula for water is $H_2o$ which shows that it is formed by combination of hydrogen and oxygen in the ratio of 2: 1 respectively.

pH of the solution is determined by litmus paper, pH paper or pH meter.

Boiling point is the temperature at which atmospheric pressure becomes equal to the atmospheric pressure.
