If a 1.00-g piece of gold (density = 19.32 g/cm3) is hammered into a sheet measuring 8.0 x 5.0 ft, what is the average thickness of the sheet in meters? How might the thickness be expressed without exponential notation, using a appropriate metric prefix?
The pressure on 200 ml of oxygen gas changes from 380 mm hg to 760 mm hg. The temperature does not change. What is the new volume of the oxygen gas?
A mixture of three gases has a total pressure of 1380 mm Hg at 25 oC. If the mixture contained 56 grams CO2, 3.04 mol CO and 9.03 X 1023 atoms of argon, the partial pressure of argon would be about
react ammonia with a halogenated alkane, will you get only one organic product? Why or why not?
What is the pH at the equivalence point when 100.00 mL of a 0.200 M solution of acetic acid (CH3COOH) is titrated with 0.10 M NaOH to its end point?
Phenol is a weak organic acid with Ka=1.0x10^-10. How many grams of phenol do you need to add to 500. mL of water to make a pH=5.75 solution

I understand that the height of a peak in NMR spectroscopy indicates the number of identical hydrogens in that particular group. But what does it mean when peak height is measured in non-H units lacking a common denominator
Calculate the equilibrium constant for this overall reaction: CH3COOH(aq) + IO^-(aq) CH3COO^-(aq) + HIO(aq) K=
Carbon-dating evaluates the ratio of radioactive carbon-14 to stable carbon-12. Given the amount of carbon-12 contained a measured sample cut from the document, there would have been about 1.3 × 10-12 grams of carbon-14 in the sample when the parc..
