How Much Limestone is Needed to React with 100 kg of Clay to Produce Cement?

Click For Summary
SUMMARY

The discussion centers on the chemical reaction required to produce cement from limestone (calcium carbonate) and clay (aluminum silicate). The balanced equation for this reaction is 4CaCO3 + Al2(SiO3)3 -> CaO + 4CO2 + Al2O3 + 3CaSiO3. To react with 100 kg of clay, the factory needs to calculate the corresponding amount of limestone based on the stoichiometric ratios derived from the balanced equation.

PREREQUISITES
  • Chemical stoichiometry
  • Knowledge of balanced chemical equations
  • Conversion between kilograms, grams, and moles
  • Understanding of cement composition
NEXT STEPS

Homework Statement


1) If limestone (calcium carbonate) and clay (assume aluminum silicate) are mixed together and heated then the result is cement. Cement is a mixture of calcium oxide, carbon dioxide, aluminum oxide, and calcium silicate. These bags can be purchased at any building supplies store. Write the balanced equation for this reaction.

2)If the factory has 100.0 kg of clay in its reaction vessel, then how much limestone will they need to exactly react with the clay to produce the cement?

You can use the chemical equation you have written. The reactants always react in a constant ratio of masses. And that ratio of masses can be found from the chemical equation.
 
kg>g>mol for a start.

clay = aluminum silicate
