Why is it diamagnetic instead of paramagnetic
An element is diamagnetic if it has no unpaired electrons. Anelement is paramagnetic if it has unpaired electrons. If sulfur has unpaired electrons in the last p orbital (1s22s2 2p6 3s2 3p4), why is it diamagnetic instead of paramagnetic?

Aspirin is a monoprotic acid; its formula isHC9H7O4. Acertain pain reliever was analyzed for aspirin by dissolving 0.250 g of it in water and titrating it with0.0300 M KOH solution. The titration required 29.40 mL of base.
Two point charges, +2.0 uC (micro Coulomb's) and -4.0 uC (micro Coulomb's), lie 0.45 m apart on the x-axis. Are there any points on the x-axis where the electric potential is zero? If so, find the point(s). If not, explain.
An electron moves through an electric field, and its speed drops from 2800 m/s to 1900 m/s. What's the potential difference between the two points at which the speed was measured?
