Statement I: Chemical formula represents the elements present in a compound.

Statement II: The chemical symbol $\text{CO}$ and $\text{Co}$ represent the same substance.

• A. Statement I is true but II is false
• B. Statement I is false but II is true
• C. Both statements are true
• D. Both statements are false

Answer 1

The correct option is A Statement I is true but II is false

Chemical formula represents the elements present in a compound. In the above statement $\text{CO}$ represents the chemical formula of carbon monoxide.

However, $\text{Co}$ is the symbol for the element cobalt. Hence, statement II is false while statement I is true.
