4NH3+5O2=4NO+6H2O which reaction is this?

Question

I want to know how can we find out chemical reactions

Answer 1

You present the reaction of 4NH3 + 5O2 ==> 4NO + 6H2O

You ask which reaction this is.  First, it can be viewed as being of the form A + B ==> C + D which would be SYNTHESIS or COMBINATION reaction.  Second, you can see that on the left side of the equation O2 has an oxidation number of zero.  On the right side it has an oxidation number of 2-.  Nitrogen on the left side has an oxidation number of 3- and on the right side it is 2-.  So, this is an OXIDATION-REDUCTION reaction.
