Question

HCIO,

Answer 1

Answer:

$\boxed {\boxed {\sf B. \ 3}}$

Explanation:

First, identify the elements.

• H: Hydrogen
• Cl: Chlorine
• O: Oxygen

Next, identify any subscripts or coefficients. This would indicate there are multiple atoms of each element or group of elements.

There are none, so each element has 1 atom.

There are 3 elements with 1 atom each, so 3*1= 3

This chemical formula has 3 atoms and B is correct.

Answer 2

B) 3, 1 hydrogen, 1 chlorine, and 1 oxygen
