If the pKa for acetic acid, found in commercial white vinegar is 4.754 at 298K, then calculate the pH, percent ionization, and pOH of a 0.585 M acetic acid of 5% vinegar solution. Do not forget to first determine the Ka, setup an "ICE" table, define the equilibrium concentrations of the finally and the significantly present at equilibrium.
a sample of neon is collected at 2.7 atm and 12.0 degrees celcius. if has a volume of 2.25 l. what would be the volume
Why don't we observe the deBroglie wavelength of everyday macroscopic objects (such as a moving car or a thrown baseball)? The wavelength is too small relative to the size of macroscopic objects to be observed.
HNO3 has 2 dissociating ions whereas Al(NO3)3 has 4, which should result in a higher conductance value. Would this have something to do with aluminum nitrate being paired with water as a solid?
Design a synthesis of 4-(carboxymethyl)-nitrobenzoic acid starting with benzene and any other necessary reagents

A 100.0 mL sample of 0.18 M HClO4 is titrated with 0.27 M LiOH. Determine the pH of the solution before the addition of any LiOH.
Calcium nitrate are mixed with 15.0 mL of 0.300 M potassium hydroxide, how many moles of calcium hydroxide will be expected to be made?
a mixture of three gases has a total of 756 mm Hg. If the pressure of nitrogen is 612 mm Hg and the pressure oxygen if 100 mm Hg, what is the pressure of the carbon dioxide gas in the mixture?
Frank and Oswalt report a molar absorptiity of 4700 L mol ^-1 cm ^-1 for the thiocyanatoiron (III) ion.
An automobile tire has a maximum rating of 38 psi (gauge pressure). The tire is inflated (while cold) to a volume of 11.8L and a gauge pressure of 36.0 psi at a temperature of 12.0C. While driving on a hot day, the tire warms to 65.0C and its volu..
