Question

module 1 lesson 3 - sept 15

1. the chemical formula for water is
2. water is a molecule, which means it is partially negative near the oxygen atom.

Explanation:

Step1: Recall water's formula

The chemical formula for water is $H_2O$.

Step2: Understand polarity

In a water molecule ($H_2O$), oxygen is more electronegative than hydrogen. This causes the electrons in the $O - H$ bonds to be pulled closer to the oxygen atom, making the oxygen - side of the molecule partially negative.

Answer:

1. $H_2O$
2. polar
