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

This problem is requiring the balanced chemical equation that takes place when copper hydroxide and potassium sulfate are produced when reacting potassium hydroxide with copper sulfate.
<h3>Balancing chemical equations:</h3>In chemistry, balancing chemical equations is based on the law of conservation of mass, which demands us to have equal number of atoms on both sides of the chemical equation. This can be accomplished by inserting coefficients in front of the chemical species.
For this particular case, we have potassium hydroxide with copper sulfate on the reactants side, however, copper can be copper (I) or copper (II) as it has 1+ and 2+ as its possible oxidation numbers. In addition, copper hydroxide and potassium sulfate as the products. Hence, we can assume this is all about copper (II) so we can write:
As we can see, potassium, hydrogen and oxygen have two atoms each on the products side, but just one on the reactants side; drawback we can overcome by putting a 2 in front of KOH so as to balance it:
