Answer:
the answer is a. 0.0012km
Avogadro's number; it describes the number of representative particles in one mole of a substance. Avogadro's number is. 6.022×10^23mol
Since the leaving ability of the halide ions increasees as the basicity of the halide decreases.
If the basicity of the halide decreases as the its conjugate acid is strong.
Since the pKa value of conjuage acid of haldie is 3, it is a weak acid. So, it halide is not a good leaving group.
Therefore the answer is No, because a good leaving group is the conjugate base of a strong acid. The halide not acidic enough to be a good leaving group.
Chemical change
Explanation:
Often times, in chemical reactions, a temperature change indicates that a chemical change has occurred.
What is a chemical change?
- It is a kind of change in which new products are formed.
- Chemical changes are usually accompanied by energy changes in reactions.
- The process is not easily reversible.
- It usually involve a change in mass.
- Requires considerable amount of energy
When temperature change occurs, it usually denotes chemical change.
