Complete the following reaction and include All possible isomers of the product. One equivalent of each ligand is added to the reaction at the same time.
How will buffer capacity change if you add 0.2 M of benzoic acid to the buffer made of 0.3 M of acetic acid
Calculate the solubility of Ba(IO3)2 in a solution containing 200 mL of .010M Ba(NO3)2 and 100 mL of .10M NaIO3. Ksp Ba(IO3)2 = 1.57 x 10^-9
A solution of HClO4 was standardized by dissolving .4125g of primary-standard-grade HgO in a solution of KBr. The liberated OH consumed 46.51mL of the acid. Calculate the molarity of the HClO4.
Balance the following redox equation . Once you have balanced the equation calculate how many grams of ammonia will be produced starting from 10 g of Zn
Explain for which of the following species resonance is an important property: HONO, HONO2, N3-, NO2-, NO2.
A gas occupying a volume of 395 mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final volume?
.At 25°C and 1.0 atm, 0.25 g of a gas dissolves in 1.00 L of water. What mass of the gas dissolves in 1.00 L of water at 25°C and 3.0 atm?
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule.
An ideal gas is allowed to expand from 8.40L to 12.6L at constant temperature. By what factor does the volume increase. The pressure will increase by same factor
