400

Name all 7 common strong acids

(Bonus 200 points if you can name them all in order of strongest to weakest pH)

Perchloric acid (HClO₄), Hydroiodic acid (HI), Hydrobromic acid (HBr), Hydrochloric acid (HCl), Sufuric acid (H₂SO₄), Nitric acid (HNO₃), Chloric acid (HClO₃)

500

Which of the following species is NOT planar?

A.) CO₃^2-

B.) NO₃^-

C.) BF₃

D.)PCl ₃

D.) PCl₃

The electron pair causes a disruption in the planar compound. Each individual chlorine atom experiences repulsion from the lone electron pair,  causing the Cl atoms to bend together. This gives this compound a trigonal pyramidal shape instead of a planar geometry.
