Calcium Carbonate and aluminum silicate are mixed together and heated. A mixture of calcium oxide, carbon dioxide, aluminum oxide and calcium silicate is produced. Write the balanced equation for this reaction.
My Work:
4CaCO3(s) + Al2(SiO3)3(s) → CaO(s) + 4CO2(g) + Al2O3(s) + 3CaSiO3(s)
Are these states of matter correct? I had some trouble finding a solubility chart that contains silicate but I think I finally got it. I really appreciate your help.
They look ok to me. Here is a simplified table summary I use.

Your balanced equation is correct. However, the states of matter you have assigned are not entirely accurate. Let me explain how to determine the correct states of matter in a chemical equation.
When writing a balanced equation, it is important to include the correct states of matter (s for solid, g for gas, l for liquid, and aq for aqueous solution) to fully describe the reaction. The states of matter can be determined by considering the solubility rules for each compound involved.
In this case, we have:
CaCO3(s) + Al2(SiO3)3(s) → CaO(s) + CO2(g) + Al2O3(s) + CaSiO3(s)
Calcium carbonate (CaCO3) is a solid, so it is correctly denoted as (s). Aluminum silicate (Al2(SiO3)3) is also a solid.
When calcium carbonate is heated, it decomposes to form calcium oxide (CaO) and carbon dioxide (CO2). Calcium oxide is a solid and carbon dioxide is a gas, so their states are correctly indicated as (s) and (g) respectively.
For aluminum silicate, it undergoes a reaction with heat to form aluminum oxide (Al2O3) and calcium silicate (CaSiO3). Both aluminum oxide and calcium silicate are solids, so their states are correctly represented as (s) in the balanced equation.
Therefore, the correct balanced equation with the accurate states of matter is:
CaCO3(s) + Al2(SiO3)3(s) → CaO(s) + CO2(g) + Al2O3(s) + CaSiO3(s)
It's always a good idea to consult reliable reference materials or sources to determine the solubility or state of matter for certain compounds if you are unsure.
