Calculate the solubility at 25 degrees Celsius in grams per liter of AgI in a solution that is 0.15 M in potassium iodide and 0.25M in ammonia. State any equilibrium constants you use.
The solubility of AgCrO4 is several times greater than that of AgCl, so the red precipitate cannot form until all the chloride ions have effectively been removed from the solution.
Among the non metallic elements, the change in atomic radius in moving one place left or right in a row is smaller than the change in moving one row up or down. Explain these observations.
a sample of gas with a mass of 1.80 g occupies a volume of 921 ml at a pressure of 733 torr and a temperature of 24 c.
Write the chemical equation for the following reaction: Add 1mL of 6M HCl to 1mL of 0.5M Na2SO4. Add a few drops of 1M BaCl2. How do your incorporate the BaCl1 into the chemical equation
In a coffee-cup calorimeter, 1.50 g of NH4NO3 is mixed with 76.0 g of water at an initial temperature of 25.00°C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.65°C.
What is the Ka for the unknown acid?
What are the signs of Hvap and Svap for water. Do you expect the signs of these quantities to be the same for other liquids. Explain.
The reaction vessel feels cooler. b.The value of K becomes smaller. c.The equilibrium will shift to the left. d.The reaction vessel feels warmer.
For the reactions of the alkyl halides with sodium iodide in acetone, does the type of halide affect the rate of the reaction? For the reactions of the alkyl halides with 1% ethanolic silver nitrate, does the type of halide affect the rate of the ..
