Calculate the amount of 0.020 M KMnO4 solution required to completely oxidize 37.99 ml of .100 M FeSO4 in an acidic solution according to the following equation. Your answer should be in mL.
How many moles of BCl3 are needed to produce 25.0 g of HCl(aq) in the following reaction?
A buffer is prepared by adding 1.00 L of 1.0 M HCl to 750 mL of 1.5 M NaHCOO. What is the pH of this buffer? Ka = 1.7 × 10-4
if 2.67 mL of 0.205 M KOH is required to completely neutralize 25.0mL of a CH3COOH solution, what is the molarity of the acetic acid solution?
Calculate the excluded volume for one mole of molecules, which is the constant b. How does this compare with the sum of the volumes of 1 mole of the same molecule
consider a .7 L of a buffer composed of 0.4 M HClO and 0.5 NaClO? How many moles of strong base could this buffer withstand?
A system consists of 6.00 moles of benzene. It is initially at a temperature of 76.0°C, a pressure of 0.878 bar, and a volume of 534.7 cm3. Calculate the volume of the system at the end of this process.
1.0 mol of CaCN2 and 1.0 mole of water are mixed together: CaCN2 + 3H2O → CaCO3 + 2NH3 How much NH3 could be produced?
Calculate the half-life (in s) of a first-order reaction if the concentration of the reactant is 0.0654 M 18.4 s after the reaction starts and is 0.0112 M 82.9 s after the reaction starts.
determine the specific heat capacity of a metal that has a mas of 14 grams. As the metal cools from 400 degrees celcius to 200 degrees celcius, 364 joules of heat is released
A certain liquid has a vapor pressure of 92.0 Torr at 23.0 °C and 353.0 Torr at 45.0 °C. Calculate the value of ?H°vap for this liquid and calculate the normal boiling point of this liquid in °C.
Water boils at a much higher temperature than all other molecules of similar molecular weight because: it makes very strong hydrogen bonds
