Question

level 3
q3
water is made up of two atoms of hydrogen and one atom of
a. nitrogen
b. hydrogen
c. oxygen
d. carbon

Explanation:

The chemical formula of water is \(H_2O\), which means each water molecule consists of two hydrogen (\(H\)) atoms and one oxygen (\(O\)) atom. Nitrogen (\(N\)) is not in water's composition, having two hydrogen atoms would repeat and not form water, and carbon (\(C\)) is part of compounds like carbon - based molecules (e.g., carbohydrates) but not water. So the correct option is the one with oxygen.

Answer:

C. Oxygen
