Question

A water molecule is formed from two hydrogen atoms and one oxygen atom. Fill in the table for 2, 5, 10 and 20 water molecules.

Answer 1

Answer:

2= 4 hydrogen atoms 2 oxygen atoms

5= 10 hydrogen atoms 5 oxygen atoms

10= 20 hydrogen atoms 10 oxygen atoms

20= 40 hydrogen atoms 20 oxygen atoms

Step-by-step explanation:

Hydrogen atoms step by step

2*2=4

2*5=10

2*10=20

2*20=40

Oxygen atoms step by step

1*2=2

1*5=5

1*10=10

1*20=20
