EXPERT ANSWER

Dear parent,

Zisha Fernandes has provided absolutely correct answer.

Pure water contains two hydrogen atoms and one oxygen atom. Hydrogen and oxygen respectively combine together in the ratio of 1:8 by mass to form water. The ratio by the number of atoms for water will always be H : O = 2 : 1. Thus, 18 g of water contains 2 g of hydrogen and 16 g of oxygen. This can be expressed in the form of the following equation.

2H2 + O2 → 2H2O

@Zisha, Good effort! Your answers are really helpful to all the users of this community. Keep writing!!!

Cheers!!
