How much sulfur (in tons), present in the original materials, would result in that quantity of SO2? (5 points) 5.Each copper(II) sulfate unit is associated with five water molecules in crystalline Copper(II) sulfate pentahydrate (CuSO45H2O). When this compound is heated in air above 100oC, it loses the water molecules are also its blue color:CuSO45H2O → CuSO4+ 5H2If 9.60 g of CuSO4 are left after heating 15.01 g of the blue compound, calculate the number of moles of water originally present in the compound. (5 points) O 6.The fertilizer ammonium sulfate [(NH4)2SO4] is prepared by the reaction between ammonia (NH3) and sulfuric acid:2 NH3(g) + H2SO4(aq)(NH4)2SO4(aqHow many kilograms of NH3are needed to produce 1.00 × 105kg of (NH4)2SO4?(5 points) ) 7.Nitric acid (NO) reacts with oxygen gas to form nitrogen dioxide (NO2), a dark brown gas: 2NO(g) + O2(g) → 2NO2(In one experiment 0.886 mole of NO is mixed with 0.503 mol of O2. a.Calculate which of the two reactants is the limiting reagent.
