Answer:
CaCO₃(s) → CaO(s) + CO₂(g)
Explanation:
The decomposition reaction always make two compounds from one.
The products always have simpler chemical structure, originated from a determined compound. This can happens spontaneously or by a third party.
A notable example of decomposition is hydrolysis. As for example the case of water, which decomposes and generates oxygen and hydrogen gas
2H₂O (l) → 2 H₂ (g) + O₂ (g)
In this case, the calium carbonate decomposes into CaO and CO₂
These two, are the products of the decomposition.
Of course, the unique reactant is the Calcium Carbonate
The balanced equation is:
CaCO₃(s) → CaO(s) + CO₂(g)
Answer:
CaCO3(s) → CaO(s) + CO2(g)
Explanation:
Step 1: Data given
Solid calcium carbonate = CaCO3(s)
solid calcium oxide = CaO(s)
gaseous carbon oxide = CO2(g)
Step 2: The unbalanced equation
CaCO3(s) → CaO(s) + CO2(g)
This equation is already balanced. We don't have to balance anything.
The balanced equation is:
CaCO3(s) → CaO(s) + CO2(g)
