what causes an increase in the solubility of a gas in a solvent in which the gas does not react with the solvent to form a new substance?
Identify the catabolic pathways used by the following bacteria : pseudomonas, lactobacillus, alcaligenes
a 130g piece of metal is heated to 286C and dropped into 87.0g of water at 26C, if the final temperature of the water is 58.3C.
an acetic acid solution of 2.87 pH is titrated with 1.5 mL of bromocresol green. When the color changes to light green
An open flask sitting in a lab fridge looks empty, but we know that actually it is filled with a mixture of gases called air.
Assuming the solution has a heat capacity of 4.18 J/°C·g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
Write the Nernst equation for this reaction, and then replace the molality of H+ with a relation using Kw and the molality of OH-. Rearrange this expression to solve for pKw (=-logKw) in terms of the standard and measured cell potentials and the g..

If the volume of ocean water is 5.4*10^20 contains 4.1 percent sodium chloride ("salt") by mass and the density of the water is 1.86 g/mL.
Given that the solubility of a compound X is 0.60 g/100 mL in ether and 0.12 g/100 mL in water. (a) What is the amount of X in mg that is extracted from a solution containing 60 mg of X in 60 mL of water
Use the initial volume of acetic acid, the volume of NaOH required to reach the equivalence point and the value of the molarity of NaOH that you obtained when you standardized this solution against KHP in the strong-acid/strong-base experiment to ..
