Answer:
We’re asked to write the balanced chemical equation for the reaction of N2 and O2 based on the given diagram.
Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.
The reactants are:
3 moles N2 (blue)
9 moles H2 (white)
The equation for the reaction can be written as:
N2 + H2 → NH3 (not balanced)
