Question

Which of the following is made up of atoms of two different elements?

• A. Ozone
• B. Water
• C. Glucose
• D. Sulphuric acid

Answer 1

The correct option is B Water

Ozone has the chemical formula $O_3$, that is made up of atoms of the same element (oxygen).

Water is made up of atoms of O and H and has the formula $H_{2}O$.

Glucose has the formula $C_6{H}_{12}{O}_6$, which means it made up of atoms of C, H and O.

Finally, sulphuric acid is made up of atoms of H, S and O and has the formula $H_{2}S{O}_4$.

So, the correct option is B.
