From XNH3+YO2=ZNO+QH2O. find the value of Z?

The value of Z is 6.

Do you have a question? If the object is to balance the equation, I don't think the value of Z is 6.

How do you get Z as 6

solve it out

To me is 4
4NH3+502=4NO+6H20

the workings please

I think the answer is 4
4NH3 + 5O2 - 4NO + 6H2O
With 6 being the answer the equation would not be balanced or correct

4 for x
5 for y
4 for z

Please show the workings.... is it 4 or 6

Value of
Z is 4
Y is 5
X is 4
