Answer:
atomic, neutrons
Explanation:
the mass number of an atom is equal to the sum of the protons and neutrons in the nucleus of the atom.
Radiant energy is converted to electrical energy, when a solar panel uses sunlight to provide power to a house.
<h3>
What is electrical energy?</h3>
- Electrical energy is produced when electrically charged particles move, producing energy.
- Electrical energy is a general term that describes energy that has been transformed from electric potential energy.
- Electric current and electric potential given by an electrical circuit serve as the source of this energy (e.g., provided by an electric power utility).
- This electric potential energy stops being electric potential energy after it has been changed into another form of energy.
- Because of this, all electrical energy is potential energy before it is used.
- Electrical energy can always be referred to as another type of energy once it has been transformed from potential energy (heat, light, motion, etc.).

Answer:
C. 7.50g
Explanation:
The percent (%) by mass of a solute in a solution refers to the number of grams contained in 100g of solution by that solute. In this case, 5% by mass of pottasium chloride (KCl) means 5g of KCl is contained in 100g of solution.
Therefore, in 150g of solution, there would be:
5g/100g × 150g
= 0.05 × 150
= 7.50g of KCl solute.
Hence, 7.50g of pottasium chloride would be expected to be collected by evaporating 150.0 g of the solution.
