Explanation / Answer

C3H8 + 5O2 -------->3Co2 + 4H2O
1 mole of C3H8 react with 5 moles of O2
1.27 moles of C3H8 react with = 5*1.27/1   = 6.35 moles of O2>>>answer
Q2
2Cu(s) + O2(g) ---------> 2CuO(s)
2 moles of Cu produce 2 moles of CuO
1 mole of Cu produce 1 mole of CuO
c. produce 1 mole of CuO >>>.answer
Q3
   2Cl2(g) + 4NaOH(aq) ----------> 3NaCl(aq) + NaClO2(aq)+ 2H2O(l)
4 moles of NaOH react with 2 moles of Cl2
4*40g of NaOH react with 2 moles of Cl2
24g of NaOH react with = 2*24/4*40   = 0.3 moles of CL2 >>>>answer
