Answer: Thermal decomposition
Explanation:
Decomposition is a type of chemical reaction in which one reactant forms two or more than two products.
Decomposition reactions require breaking of bonds which require energy and thus all of the decomposition reactions are endothermic reactions. They require energy in the form of heat, electricity or sunlight and thus called as thermal, electrolytic and photolytic decomposition respectively.
The decomposition reaction for calcium carbonate breaks down into calcium oxide and liberates carbon dioxide is :
The initial concentration of solution is 0.0693 M. The volume of solution taken is 10 mL and it is diluted to a final volume of 500 mL.
According to dilution law, the product of initial concentration and volume is equal to the product of final concentration and volume as follows:
Here, is initial concentration,
is final concentration,
is initial volume and
is final volume.
Rearranging to calculate final concentration,
Putting the values,
Therefore, concentration of the resulting solution is 0.001386 M.
