Answer:
Arrow should be yeilds, THE COEFFICIENTS are mole ratios. So every 4 moles of NH3 or ammonia produce 6 moles of H2O water
Answer:
Solution given:
3Fe+ O2. =Fe3O2
3mole. 1 mole. 1 mole
we have
3 mole of iron gives 1 moles of 1 mole of fe3O2
now
0.275 mole of iron gives 1×0.275/3=0.92mole of fe3O2
