1.The rate at which sugar dissolves in water increases with stirring BECAUSE stirring exposes the surface of a solute crystal to a less concentrated layer of solution.

2.Diamond has a high melting point BECAUSE in a diamond crystal, the carbon atoms are held in place by ionic bonds.

3.Potassium has a lower first ionization energy than lithium has BECAUSE potassium has more protons in its nucleus than lithium does.

4.Zinc metal will reduce C2+ in solution BECAUSE Zinc is a more active metal than Copper is.


These seem like pretty basic questions to me, but I disagreed with the website's answers.
