Chemical Reaction Homework: Balancing Equation for CaCO3 & Al2(SiO3)3

Click For Summary
SUMMARY

The balanced chemical equation for the reaction between calcium carbonate (CaCO3) and aluminum silicate (Al2(SiO3)3) is 4CaCO3 + Al2(SiO3)3 -> 4CO2 + CaO + Al2O3 + 3CaSiO3. This equation indicates that heating these materials produces cement, which consists of calcium oxide, carbon dioxide, aluminum oxide, and calcium silicate. To determine the physical states of the reactants and products, solubility rules can be applied, along with knowledge of the states of matter at room temperature.

PREREQUISITES
  • Chemical equation balancing
  • Understanding of chemical reactions and products
  • Knowledge of solubility rules
  • Familiarity with states of matter (solid, liquid, gas)
NEXT STEPS
  • Study advanced chemical reaction balancing techniques
  • Research the properties and applications of cement
  • Learn about solubility rules in detail
  • Explore the physical states of common chemical compounds
USEFUL FOR

Chemistry students, educators, and professionals involved in materials science or construction who need to understand chemical reactions and the properties of cement.

Homework Statement



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.

Homework Equations





The Attempt at a Solution



CaCO3+Al2(SiO3)3 -> CaO+CO2+Al2O3 +CaSiO3

I know I did not balance the equation yet. I just want to make sure I wrote it right before I do. Did I do this part right? Thanks.

So far, so good.
 

The Attempt at a Solution




4CaCO3+Al2(SiO3)3 -> CaO+4CO2+Al2O3 +3CaSiO3

Is this right? Also, how do I determine the physical state of each reactant and product? Do I use the solubility rules? Thanks for your help.

Looks good to me. Yes, solubility rules are a good start. Also, we can use a bit of personal experience too--e.g., we know CO2 is a gas at room temperature.
 
We are talking about solid, so solubility rules are a little bit off.
 
Thanks a lot.
