A manganese-containing ore is digested and chemically treated to
isolate manganese as MnO2(s). Heating the
MnO2 at 1000 °C in air converts it entirely to
Mn3O4(s).
Suppose a 2.70-g ore sample yields 0.235 g of
Mn3O4(s) by this process.
Calculate the percent Mn in the ore sample.
Calculate the percent MnO2 in the ore sample.

1.Sodium hydrogen carbonate, NaHCO3, can be decomposed completely by heating. 2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) A sample of impure NaHCO3 with an initial mass of 0.739 g yielded a solid residue (consisting of Na2CO3 and other solids) with a final mass of 0.564 g. Determine the mass percent of NaHCO3 in the sample. 2.In a process for producing acetic acid, oxygen gas is bubbled into acetaldehyde, CH3CHO, containing manganese(II) acetate (catalyst) under pressure at 60°C. 2CH3CHO(l) +...

Calcium oxide (Lime) is usually produced by heating and decomposing limestone (CaCO3), a cheap and abundant mineral, in a process: CaCO3 (s) CaO (s)+CO2 (g) a) Limestone at 25°C is fed to a continuous calcination reactor. The calcination is complete, and the products leave at 900 °C. Taking 1 metric ton (1000 kg) of limestone as a basis and elemental species [Ca(s), C(s), O2(g)] at 25°C as references for enthalpy calculations, prepare and fill in an inlet-outlet enthalpy table and...
