Question

Statement 1: An iron rod contains only iron atoms in it.

Statement 2: A glass of water contains only oxygen atoms in it.

• A. Statement 1 is true, statement 2 is false
• B. Statement 2 is true, statement 1 is false
• C. Both statements are true
• D. Both statements are false

Answer 1

The correct option is A Statement 1 is true, statement 2 is false

An iron rod is made up of iron, an element. Hence, it will contain only iron atoms in it.

However, water is a compound. A water molecule $\left(H_{2}O\right)$ is constituted by two hydrogen and one oxygen atoms. Hence, it contains both hydrogen as well as oxygen atoms in it.
