Determine from the balanced chemical reaction if the derived mole ratio is correct or incorrect.

4Zn + 10HNO3 yields 4Zn(NO3)2 + N2O + 5H2O

(4 moles Zn / 5 moles H2O)

Balanced reaction:

The mole ratio (4 moles Zn/5 moles ) is correct.

Explanation:

Oxidation:

Balance N and O:

Balance charge:    ................(1)

Reduction:

Balance N:

Balance H and O:

Balance charge:  ............. (2)

[Equation-(1)] + [Equation-(2)]:

So, balanced reaction:

Hence the mole ratio (4 moles Zn/5 moles ) is correct.
