4. The molar ration between O2 and NH3 is 3:4. So when 3.0 moles of NH3 are reacted, 3.0*3/4=2.25 moles of O2 are needed.

   So the answer is b

5. The mole of CO2=86.7/44=1.97 mol

    When 25.0g or 25.0/12=2.08 moles of C are completely reacted, 2.08 moles of CO2 could be produced.

So the yield = 1.97/2.08*100%=94.7%

   The answer is b
