Balance the following equation __N2+__O2→__N2O​
fenix001 [56]

Answer:

2N₂   +  O₂  →  2N₂O

Explanation:

Given equation:

        N₂   +  O₂  →  N₂O

In balancing a chemical equation, the number of atoms on both sides of the expression must be the same.

To solve this problem, we use a simple mathematical approach;

  put coefficients a,b and c

             aN₂   +  bO₂  →  cN₂O  

Conserving N;

                   2a  = 2c

Conserving O:

                  2b  = c

 Let a = 1, c = 1 , b  = \frac{1}{2}

   multiply through by 4

           a = 2, b  = 1 and c  = 2

 Balanced equation is;

          2N₂   +  O₂  →  2N₂O

Many gardeners add earthworms to their soil if none are already living there. Why would gardeners do this?
Ksenya-84 [330]
The correct answer is D, earthworms eat the dirt, and then release it into the soil. They turn the dirt and soil into fertilizer so to speak. Worms also leave holes in the ground, which is good for water and air for the plants roots, but that isn't an option.
