2Fe2O3 + 3C → 3CO2 + 4Fe D. How many grams of CO2 are produced from 11.42g Fe2O3?

A mixture of two metals A and B are combusted to yield a compound with the molecular formula, AB204. Mass% of oxygen in in the compound is around 45%. Determine A and B.

What mass of Cu(IO3)2 can be formed from 0.650 g of CuSO4 · 5H2O? What mass of KIO3 is needed to convert the copper in 0.2750 g of CUSO4 - 5H2O to Cu(IO3)2?

2. The hydrogen sulfide in a 50.0 g sample of crude petroleum was removed by distillation and collected in a solution of CdCl2. The precipitated CdS was then filtered, washed, and ignited to CdSO4. Calculate the percentage of H₂S in the sample if 0.1080 g of CdSO4 was recovered.

Balance these equations: C2H6 + O2 ---> CO2 + H2O H2S + SO2 ---> S + H2O CH3OH + O2 ---> CO2 + H2O

Riccardo states that the process of iron reacting with sulfur to produce iron(II) sulfide according to 16Fe + 3S8 = 8Fe2S3 16.00g of iron will react will 3.00 g of sulfur in the reaction. Do agree or disagree with this statement. Please explain.

How many grams of water would be lost if a 8.000 gram sample of PtCl4·5H2O were heated?

after doing part a and b, please offer a simple explanation to why these two values might be different.
