The type of chemical reaction is an oxidation-reduction reaction, also known as redox reaction. Batteries use this chemical reaction to do work on charge and produce voltage. The important part is called an electrochemical cell where the reaction occurs.
Examples of chemical change : 1.food scraps 2. gasoline 3. rust.
examples of physical change : 1. juice box. 2. water. 3. rubbing alcohol.<span />
Answer:
The temperature of the water increases because the average
kinetic energy of the water molecules increases.Explanation:
Answer: the answer for this question is in the pic
Explanation:
Answer:
Option (a) is the correct answer.
Explanation:
The law of conservation of energy states that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.
Therefore, the total amount of energy before and after a chemical reaction is the same. Thus, energy is conserved.
Therefore, we can conclude that option (a) is the correct answer.
