Why does every chemical reaction require a certain amount of activation energy?
1 answer:
Explanation:
Activation energy is the minimum amount of energy required for a chemical reaction to take place.
When a chemical reaction occurs then bonds between the reactants break and bonds between the products are formed. This leads to the formation of an activated complex which is also known as transition state.
So, in order to form the activated complex a minimum amount of energy is necessary and this energy is known as activation energy.

The substance that conducts electricity is dissolved in water.
So, option A is correct one.
When the sodium chloride dissolve in water , the sodium atoms and chlorine atoms separates under the presence of water molecules and exist as sodium cation and chloride anion . Now , they are free to move around in the water as positively and negatively charged ions . This separation of charge allows the solution to conduct electricity.
The solid and solid sugar does not conduct electricity because it is not dissolve in water . Similarly, sugar dissolved in water does not conduct electricity .
