Question

When the equation __no2 __h2o __o2 → __hno3 is balanced, the coefficient of hno3 is:_________

Answer 1

When the equation __$NO_{2}$ __$H_{2} O$ __$O_{2}$ → __$HNO_{3}$ is balanced, the coefficient of hno3 is 4.

An expression for a chemical reaction would be referred to as balanced if both the reactants as well as the products have an identical number of atoms with a total charge for each component of the reaction. In other words, two sides of the reaction have equal amounts of mass as well as charge.

The given unbalanced equation is  __$NO_{2}$ __$H_{2} O$ __$O_{2}$ → __$HNO_{3}$ .

It can be seen that the count of hydrogen in reactant side 2 on the other hand the count of hydrogen atom is 1.

By multiplying by 4 as the coefficient of  and $NO_{2}$  and by 2 as the coefficient of water then equation will be balanced.

The balanced chemical equation will be expressed as:

4 $NO_{2}$  + 2$H_{2} O$  +$O_{2}$ → 4$HNO_{3}$ .

Therefore, when the equation __$NO_{2}$ __$H_{2} O$ __$O_{2}$ → __$HNO_{3}$ is balanced, the coefficient of hno3 is 4.
