Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms. In ordinary water, each hydrogen ...

a water molecule always contains two hydrogen atoms and one oxygen atom. It cannot be a water molecule if it has different numbers of these atoms. The formula for water is always \(H_2\)O.

Let students know that each group should have 4 white, 3 red, 2 black, and 1 blue cube. The white ones stand for hydrogen, the red are oxygen, the black are carbon, and the blue is nitrogen. Explain ...
