How many nitrogen
atoms (N) are in 2N2

Mohit Gupta, Meritnation Expert added an answer, on 14/3/14 1. 2N denotes two nitrogen atoms. 2. N 2 denotes one molecule of nitrogen gas.

Explanation:

air quality

poor drinking water

and heavy polution

can lead to poor health

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
