valance band has lower energy level
For a lower level test with significance level (alpha) 0.01, the z value is -2.33. That is, P( z < -2.33) = 0.01. The area to the left of -2.33 is 0.01.
Continue to do the Lower level chambers intill you get up a higher level. the higher level you are the more chambers you can play. :P
It is conventionally 5% (or lower) but there is no good reason for that level.

technically, pH measures the amount of H+ in solution, so the lower the pH the more acidic the solution.. ("p" is a -log function, so pH is the same as -log of the concentration of H+) so when magnesium reacts with the acid, the acid (the substance which dissociates to produce H+ in solution) is being used up, so there's less H+ in solution, so the acidity of the solution drop, and the pH level rises.
