Examples of scenarios that would adhere to the law of conservation of energy are as follows:
- In a loudspeaker, electrical energy is converted into sound energy.
- In a microphone, sound energy is converted into electrical energy.
- In a generator, mechanical energy is converted into electrical energy
<h3>What is law is conservation of energy?</h3>
The law of conservation of energy states that energy cannot be created nor destroyed but is conserved when it is transferred from one form to another.
The law of conservation of energy is obeyed by majority of natural and artificial systems. For example;
- In a loudspeaker, electrical energy is converted into sound energy.
- In a microphone, sound energy is converted into electrical energy.
- In a generator, mechanical energy is converted into electrical energy

Answer:
b. protein
Explanation:
Proteins are biopolymers basically made of carbon, hydrogen, oxygen and nitrogen.
Triglycerides are made of a glycerol molecule esterified by three fatty acids.
Polysaccharides are carbohydrates, and therefore contain carbon, hydrogen, and oxygen.
The mineral salt contains mostly sodium chloride, although it contains some other minerals such as magnesium, potassium, iodine, among others.
The answer to this question is:
D. balanced.
Good Luck!
Answer:
Six electrons are transferred in the formation of Al₂O₃.
Explanation:
Aluminium metal and Oxygen react to form Al₂O₃ as,
2 Al + 3/2 O₂ → Al₂O₃
Oxidation number of Al on left hand side is zero, while than on right hand side in Al₂O₃ is +3. Means it has lost 3 electrons per one atom and six electrons per two atoms. Also, the oxidation number of O at left hand side in O₂ is zero, while that in Al₂O₃ it is -2 per atom and -6 per 3 atoms.
So, two Al atoms have lost 6 electrons and 3 O atoms have gained six electrons.
