<u>Answer:</u>
<em>The chemical reactions involves changes in energy due to the changes in the breaking and building of bonds.</em>
<u>Explanation:</u>
The changes in energy that chemical reactions involves are:
- <em>Endothermic(absorbing) chemical reactions.</em>
- <em>Exothermic(releasing) chemical reactions. </em>
Endothermic: The chemical reactions which absorbs the energy those chemical reactions are called endothermic chemical reactions.
Exothermic: The chemical reactions which releases the energy those chemical reactions are called exothermic chemical reactions.
The similarity in the reactions is both reactions are related to the change in energy. In one reaction the energy is absorbing and in another reaction the energy is releasing.

The elctromagnetic spectrum ranges from the radiowaves to the gamma rays. The whole spectrum is shown in the attached picture. But the optical telescope can only see the visible region. So, it only covers from the 400 nm to 700 nm frequency. It follows the ROYGBIV colors, where red has the highest frequency and violet has the lowest frequency.
Answer:
The size of the electric current is 154.74 A.
Explanation:
It is assumed that,
Charge, q = 93 C
Time,
We need to find the size of the electric current. It is equal to the electric charge per unit time. It is given by :
I = 154.74 A
So, the size of the electric current is 154.74 A. Hence, this is the required solution.
