Question

When electricity flows through water, the water molecules split into molecules of hydrogen and oxygen gas. How many oxygen (O2) molecules are produced from the splitting of two molecules of water (H2O) if the balanced equation for the reaction is as follows? 2H2O 2H2 + O2 A. 4 B. 3 C. 2 D. 1

Answer 1

The number of O2 ( oxygen) molecules that are produced from splitting of two molecules of water is 1 molecule of oxygen ( answer D)

Step-by-step explanation

A molecule - is a group of two or more atoms held together by a chemical bond.

In the reaction of splitting of 2 molecules of H2O yield 1 molecule of O2.

• 1 molecule of O2 is made up of two atoms of Oxygen held by double covalent bond.

• The two oxygen atom form molecule by sharing two valence electrons.
