The endpoint in the titration is "overshot"
A. is the reported molar concentration of the hydrochloric acid solution too high or too low. EXPLAIN
B. As a result of this poor titration technique, is the reported number of moles of B4O5(OH)4^2 would be too high or too low EXPLAIN?

Consider all the valence electron pairs of the central atom-both those that are shared in covalent bonds, called bonding pairs, and those that are unshared, called non-bonding pairs or unshared pairs.
A container consists of CO2 gas at a temperature of 15 C and at a pressure of .990 atmospheres. The volume of the container is 500 mL. How many grams of CO2 would be in the container? (1 liter equals 1000 milliliters.)
