Question

what is the chemical formula for this molecule? complete the formula below: h□o□ submit

Explanation:

Step1: Count Hydrogen atoms

The molecule has two light - colored (gray) atoms which represent Hydrogen (H). So the number of H atoms is 2.

Step2: Count Oxygen atoms

The molecule has one red atom which represents Oxygen (O). So the number of O atoms is 1.

Answer:

$\ce{H_{2}O_{1}}$ (or simply $\ce{H_{2}O}$ as the subscript 1 for O is often omitted)
