b) How many grams of carbon dioxide can be produced by burning 20.0lb of propane, the typical size of a BBG grill propane tank? Assume that oxygen is the excess reagent in this reaction.
Write the expression for the equilibrium constant, Kb, for methylamine also compute the molar concentration of OH- in the 50.0 mL sample of the CH 3 NH 2 solution.
In a fictitious lab experiment a class studied two acid base reactions and recorded the temperature change. class averages were reported 1) 30 ml of 3 molar hcl with 30 ml of 1.5 naoh change in temp was 12.2 +or - 1.3
Consider an aqueous solution that is saturated with lead iodide, lead sulfate and 0.10 M K2SO4 (a strong electrolyte). Write mass and charge balance equations that describe the system
Compute the pH of a solution prepared by dissolving 0.150 mol of benzoin acid (C6H5COOH) as well as 0.300 mol of sodium benzoate (C6H5COONa) in water sufficient to yield 0.100 L of solution. The Ka of benzoin acid is 6.30 x 10 -5
what is the [OH-] in a solution that has a pOH of 2.70? Use E notation with 3 significant figures.
assuming ideal behavior, calculate the boiling point in C of solution that contains 64.5g or the non-volatile non-electrolyte quinoline( molar mass= 129g/mole) in 500 grams of benzene. For benzene the normal boling point is 80.10 C and Kb = 2.53C/..
