A balloon at 200.ºC is inflated with hydrogen gas to a volume of 100. mL. It is then further inflated to a volume of 300. mL with oxygen gas. If the reaction between hydrogen and oxygen proceeds 100%, what is the final volume of the balloon
Calculate the pH at the equivalence point if 25.00 mL of 0.010 M barbituric acid (HC4H3N2O3) is titrated with 0.20 M NaOH. (Ka barbituric acid = 1.0 x 10^-5).
What volume of radon will be produced per hour at STP from 1.075 g of 226Ra? (t1/2 = 1599 yr; 1 yr = 8766 h; mass of one 226Ra = 226.025402 amu)

How many resonance forms are required to represent the bicarbonate ion HOCO21
The pKa of one of the hydrogen's that is attached to one of the nitrogen's of the purine guanine is 9.7. If guanine is in a solution that has a pH of 12.7, then how many carbons, nitrogen's, oxygen's, and hydrogen's does guanine predominantly have..
The density of germanium is 5.325 g/cm^3 . If you made a 4 nm quantum dot of germanium, how many atoms would it contain? Assume the dot is spherical.
