...follows: NaCl + NH3 + H? Could anyone help me out with a couple of questions. I am stuck on 3 of them! : (
Any help/ explanations would be appreciated! Thanks!
4. In industry, sodium carbonate is produced in two stages whose equations are as follows:
NaCl + NH3 + H2O + CO2 ? NH4Cl + NaHCO3
2NaHCO3 + heat ? Na2CO3 + CO2 + H2O
What’s the mass of sodium carbonate that can be produced from 1.0 t of sodium chloride? (Assume that the other reactants are in excess.)
Hint: Indicate clearly how you found the molar ratio. Use the two equations given to you above to make your calculations.
b) If 0.85 t of sodium carbonate is actually produced from 1.0 t of sodium chloride, what’s the theoretical yield percentage?
6. Sulphur (IV) oxide is one of the main causes of acid rain. This acid is formed when coal, which contains sulphur compounds, is burned in coal-fired power plants. One way of eliminating sulphur (IV) oxide is to make it react with damp, pulverized calcium carbonate. The equation for this reaction is as follows:
SO2 + CaCO3 + other reactants ? CaSO3 + other products
The total quantity of coal burned in Canada and the United States in a year is approximately 450 x 106 t.*The average quantity of sulphur in coal is 2.5%.
Calculate the mass of sulphur contained in coal.
Calculate the mass of calcium carbonate required to eliminate sulphur (IV) oxide. (You may assume that 1 mole of sulphur will produce 1 mole of sulphur (IV) oxide.)
