Since the reacting ratio of CO:CO2=3:3=1:1, the number of CO that reacts with Fe2O3 are the same.Therefore, moles of CO needed to produce 11.7moles of CO2=11.7moles
Fe2O3 +3CO --> 2Fe + 3CO22 mol Fe will be formed when 3 mol CO is used according to balanced equationTo produce 25.1 mol Fe there must be 3 mol CO/2 mol...
Solution:The balanced chemical equation:Na2S2O3(aq) + 4Cl2(g) + 5H2O(aq) --> 2H2SO4(aq) + 6HCl(aq) + 2NaCl(aq)According to the equation: n(Na2S2O3) = n(Cl2)/4Step 1 "Mass of Cl2 to moles of Cl2":Moles of Cl2 =...
2Al + Cr2O3 = Al2O3 +2 Сr1 mole of matter cntains 6.022×1023 elementary entities.1.20x1021 atoms of Al equals to 1.20x1021/ 6.022×1023 = 0.2x10-2 moles.According to the equation, n (Al2O3) =...
Molar mass of Fe2O3= (56x2) + (16x3) = 130gmol-1Molar mass of Fe= 56gmol-1From the balanced equation130g of Fe2O3 produces 2(56)g of Fe130g of Fe2O3 produces 112g of FeTherefore, 1500g will...
