Question
Calcium carbonate (CaCO3) is a common substance found in rocks. When it's heated, it breaks down to form a new solid, calcium oxide (CaO). This reaction releases carbon dioxide gas (CO2).Write a symbol equation for this reaction, including state symbols.Note: You can copy and paste this arrow: →
Solution
The symbol equation for the reaction is:
CaCO3(s) → CaO(s) + CO2(g)
Here's what each symbol means:
- (s) stands for solid
- (g) stands for gas
- → means 'reacts to form'
