If calcium carbonate) and 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. Write the balanced equation for this reaction.
My Answer:
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.
Frankly, I'm not sure what the question is AND I'm not sure I believe the information. I just don't believe cement is a mixture of CO2 and anything. That is, heating CaCO3 certainly will produce some CO2 but that isn't a part of cement.
Yes, you wrote the equation correctly, but it is not yet balanced. Let's balance it now:
CaCO3 + Al2(SiO3)3 -> CaO + CO2 + Al2O3 + CaSiO3
To balance the equation, we need to ensure that the number of atoms on both sides of the equation is the same. Let's start by balancing the calcium atoms:
CaCO3 + Al2(SiO3)3 -> CaO + CO2 + Al2O3 + CaSiO3
We have 1 calcium atom on the left side, but there are two calcium atoms on the right side. To balance this, we add a coefficient of 2 in front of CaCO3:
2CaCO3 + Al2(SiO3)3 -> CaO + CO2 + Al2O3 + CaSiO3
Now, let's balance the aluminum atoms:
2CaCO3 + Al2(SiO3)3 -> CaO + CO2 + Al2O3 + CaSiO3
On the left side, we have 2 aluminum atoms, but there are only 1 on the right side. To balance this, we add a coefficient of 2 in front of Al2O3:
2CaCO3 + Al2(SiO3)3 -> CaO + CO2 + 2Al2O3 + CaSiO3
Finally, let's balance the silicon atoms:
2CaCO3 + Al2(SiO3)3 -> CaO + CO2 + 2Al2O3 + CaSiO3
On the left side, we have 3 silicon atoms, but there is only 1 on the right side. To balance this, we add a coefficient of 3 in front of CaSiO3:
2CaCO3 + Al2(SiO3)3 -> CaO + CO2 + 2Al2O3 + 3CaSiO3
Now the equation is balanced, and the coefficients in front of each compound represent the ratio of molecules or formula units involved in the reaction.
