Answer:
(3) saturated
Explanation:
Hello,
In this case, a solution that is at equilibrium must be (3) saturated as at the equilibrium, the entire solute is completely dissolved into the solvent, so no leftovers are present. Unsaturated solutions are not at equilibrium since there is a portion of solvent that is not contributing to equilibrium. Concentrated solutions are not at equilibrium since they could have more solution than allowed into the solvent.
Best regards.

(2) reduction (4) nuclear fusion
Answer:
Nuclear Fusion
Explanation:
In nuclear fusion two lighter nuclei combine together in order to form one heavier nucleus.
For example, the energy generated from the Sun is made by nuclear fusion: Two hydrogen (H, atomic number 1) nuclei combine in order to form one helium (He, atomic number 2) nucleus.
Nuclear fission is the opposite reaction, in which one heavier nucleus splits into two lighter nuclei.

The statement is conclusive evidence that mixing sugar in water is a physical change is there is no molecular change. Therefore, option D is correct.
A change known as physical change occurs when the physical characteristics of matter change. Physical changes include those in color, odor, solubility, and the condition of matter, among others.
Melting, turning into a gas, changing strength or durability, changing crystal structure or texture, and changing shape, size, color, volume, or density are a few examples of physical qualities.
Because sugar molecules are spread throughout the water, but the individual sugar molecules remain unaltered, dissolving sugar in water represents a physical change.
Thus, option D is correct.
