It IS balanced.  There are 4 Hydrogen atoms on the left and the right and 2 Oxygen atoms on the left and the right.  

Step-by-step explanation:

Answer 2

Answer : The correct option is, Yes, the equation is balanced. There are the same number of Hydrogen (H) and Oxygen (O) atoms on both sides of the equation.

Step-by-step explanation :

Law of conservation of matter : It states that matter can neither be created nor be destroyed but it can only be transformed from one form to another form.

The balanced chemical reaction always follow the law of conservation of mass.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

The given chemical reaction is,

$2H_2+O_2\rightarrow 2H_2O$

This reaction is a balanced chemical reaction in which number of atoms of hydrogen and oxygen are equal on the both side of the reaction. So, this reaction obey the law of conservation of matter.
