0+0,2=2N
0,2=2N
2N=0,2
N=0,1

Answer 2

The equation you've provided seems to be a chemical reaction involving nitrogen oxides (NO and NO2) and oxygen (O2), along with an energy change of 113 kJ (kilojoules). However, there seems to be a little confusion in the equation's format. Let's clarify it:

The balanced chemical equation for the reaction involving nitrogen dioxide (NO2) and oxygen (O2) to form nitrogen dioxide (NO2) with an energy change of 113 kJ is as follows:

2NO + O2 → 2NO2 + 113 kJ

In this reaction, two molecules of nitric oxide (NO) and one molecule of oxygen (O2) react to form two molecules of nitrogen dioxide (NO2) while releasing 113 kJ of energy. The positive value of energy indicates that the reaction is exothermic, meaning it releases energy in the form of heat.

Please note that the reaction equation you provided is a bit unconventional in terms of formatting. Normally, the energy change would be written on the right side of the equation as a product, and it's unusual to have both reactants and products with the same chemical formula. If you meant a different reaction or have further questions, feel free to ask!
