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 atoms are constantly in motion
Answer:
The correct option is (D).
Explanation:
Uncertainty means lack of certainty in any calculations. It is the quantification of doubts after the calculations are done.
In this problem, we need to find the uncertainty in the measurement 0.0035 mg. There are 4 numbers after decimal. It means uncertain digit 1/10000 is the smallest scale division.
Hence, the uncertainty in the measurement 0.0035 mg is +0.0001 mg
