Answer:
The electron from the ground state to occupy a next energy level. In this case,we say that the electron is excited

The solubility of substance depends upon the temperature. In present case, the solubility of KCl is 84g/100g at <span>50.oC.
This means that, maximum 84g of KCl can be dissolved in 100g of water (at </span>50.oC) to form solution. This solution is referred as saturated solution.
Thus, 84g of <span>KNO3 must be dissolve in 100 grams of water to form a saturated solution at 50 oC.</span>
The reaction is balanced
The equilibrium constant is defined as the concentration ratio of the products and reactants. They are not considered pure solids and liquids.
So the answer is option B.
I am pretty sure the correct answer is C. Water has large heat capacity meaning it can absorb a lot of energy before changing temperature. That helps the body regulate heat since it can be exposed to different environments and experience small temperature changes.
I hope this helps. Let me know if anything is unclear.
