Which of the following is an example of electrical energy being converted to chemical energy?
2 answers:
An example of electrical energy being converted to chemical energy: D. A storage battery is charged using an electric current.
<h3>Further explanation </h3>Energy can be interpreted as the ability to do work
There are several examples of energy
- 1. Kinetic energy is the energy possessed by objects due to their motion
m = mass
v = velocity
- 2. Potential energy is the energy that an object has because of the location of that object. Usually it is related to the force of gravity
g = acceleration due to gravity
h = height
- 3. Mechanical energy is the sum of kinetic energy and potential energy
Energy can change into other forms of energy but the magnitude will remain the same. This is in accordance with the law of conservation of energy which states that
<em>Energy can change to other forms but cannot be created or destroyed </em>
Let's look at the answer choices
A. The wheels on a machine begin to turn and move a conveyer belt.
the mechanical energy changes into kinetic energy
B. An electric furnace begins to emit heat to warm a house.
the electrical energy changes into heat energy
C. A loudspeaker, which is plugged in to the wall, begins to project sound.
the electrical energy changes into sound energy
D. A storage battery is charged using an electric current.
the electrical energy changes into into chemical energy

Explanation:
The reaction expression is given as;
2H₂ + O₂
→ 2H₂O
From the balance reaction expression:
2 mole of hydrogen gas combines with 1 mole of oxygen gas on the reactant side;
This produces 2 mole of water on the product side of the expression.
The product is in liquid form.
This reaction is a synthesis reaction because a single product is formed from two reactants.
