Answer 2

Answer:

2NO2 + 7H2 → 2NH3 + 4H2O

Explanation:

1 Enter an equation of a chemical reaction and click 'Balance'. The answer will appear below

2 Always use the upper case for the first character in the element name and the lower case for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.     Compare: Co - cobalt and CO - carbon monoxide

3 To enter an electron into a chemical equation use {-} or e

4 To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}.

Example: Fe{3+} + I{-} = Fe{2+} + I2

5 Substitute immutable groups in chemical compounds to avoid ambiguity.

6 For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced,

but PhC2H5 + O2 = PhOH + CO2 + H2O will

7 Compound states [like (s) (aq) or (g)] are not required.

8 If you do not know what products are enter reagents only and click 'Balance'. In many cases a complete equation will be suggested.

9 Reaction stoichiometry could be computed for a balanced equation. Enter either the number of moles or weight for one of the compounds to compute the rest.

10 Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents.
