Zinc(II) sulfide reacts with oxygen according to the reaction:
2 ZnS(s) + 3 O2 (g) ? 2 ZnO(s) + 2 SO2 (g)
A reaction mixture initially contains 4.2 mol ZnS.
a. How many moles of oxygen will be required to react with ZnS?
b. Assuming there is enough oxygen,
i. How many moles of SO2 gas will be expected to be produced in the reaction?
ii. How many grams of ZnO will be produced
A gaseous reaction occurs at a constant pressure of 50. atm and releases 74.2kj of heat. Before the reaction, the volume of the system was 8.00L After the reaction, the volume of the system was 2.80L
Compute the molar concentration of Cl- in the standard KNO3 solution if the flask is rinsed only one time with distilled water.
The sample requires 48.24 mL of 0.08893 mol/L Na2S2O3 to reach the equivalence point. Assuming that the AU3+ and Li+ ions are unreactive during the titration, determine the mass percent of LiCLO in the sample.
