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+Al2(SiO3)3->CaO(s)+4CO2(g)+Al2O3+3CaSio3
I could only determine the physical state of calcium oxide and carbon dioxide. How do I determine the physical state of the others? Thanks.
you need the solubilities rules
I agree.
To determine the physical state of the substances in a balanced equation, you need to consider their common states at room temperature and pressure (25°C and 1 atm). Here are some guidelines to help you determine the physical states:
1. Most elements are in their standard state, which means they are in their typical physical state at room temperature and pressure. For example:
- Oxygen (O2) is a gas.
- Nitrogen (N2) is a gas.
- Sodium (Na) is a solid.
- Chlorine (Cl2) is a gas.
2. Common compounds often have a specific physical state at room temperature and pressure:
- Solids are denoted by "(s)" after the chemical formula. For example, CaO(s) represents calcium oxide as a solid.
- Gases are denoted by "(g)" after the chemical formula. For example, CO2(g) represents carbon dioxide as a gas.
- Liquids are denoted by "(l)" after the chemical formula. However, in this reaction, there are no liquids involved.
Using these guidelines, you can identify the physical states for the remaining substances in your balanced equation:
4CaCO3(s) + Al2(SiO3)3(s) → CaO(s) + 4CO2(g) + Al2O3(s) + 3CaSiO3(s)
Make sure to adjust the physical state symbols accordingly based on these guidelines.
