Chemical energy can be transformed into electrical energy and mechanical energy.
Explanation:
Chemical Energy transformed into Electric Energy - widely exploited by batteries. The chemical reactions that are taking place in these devices can be used as a direct source of electrical energy. Some may be reversed and some non - reversible are called rechargeable. Never attempt to recharge regular batteries as there may be an explosion with burns and material and personal damage.
Chemical energy transformed into mechanical energy: An explosion is always accompanied by a shock wave. The shockwave is nothing but the air being moved very quickly, a kind of supersonic wind that is accompanied by a crash. Explosives are an example of this type of transformation.
The sperm and egg have 1/2 the amount because when the sperm fertilizes the egg, it equals out to the regular amount of chromosomes. That is why we have half chromosomes from our dad and half chromosomes from our mom, equaling out to normal amount of chromosomes.
