Question

Give one example of decomposition reaction in which solid and gas are two products obtained.

Answer 1

Answer:

CaCO3-CaO+CO2

Explanation:

In this reaction calcium oxide is solid and cabondioxide is a gas.

Answer 2

Answer:

CaCO3 ------------------------- CaO (Metal / Solid) + CO2 (Gas).

Explanation:

When speaking of decomposition reaction, this is not a special type of chemical reaction. So there are many examples where the end products formed during this reaction will give solid and gas.

The reaction takes place and as a result of this reaction, the single compound breaks down.  After breaking down the compound into two simpler forms of elements or substances.

The decomposition reaction, in simple terms can be written as:-

AB------------------- A  +  B.

One of the most important things that you need to keep in your mind is that Decomposition reactions take place only if energy in some form is supplied to the system.

This energy can be in any form – Light, heat or even electricity.

Now coming to your question, you asked an example of such decomposition reaction in which the End products formed are Solid and gas.

I will take n example in which decomposition reaction takes place and the end products formed are also compounds – But solid and gas.

General reaction is when Metal carbonate decomposes to give solid (metal oxide) and Gas (carbon dioxide). So the compound that decomposes is Calcium carbonate and it gives carbon dioxide gas and calcium oxide (metal).

The reaction is written as below:-

CaCO3 ------------------------- CaO (Metal / Solid) + CO2 (Gas).
