What is the percent ionization at equilibrium in a 0.60 M solution of dimethylamine, (CH3)2NH (Kb = 5.1 × 10-4), at 25oC?
A. 100%B. 2.9%C. 0.085%D. 1.7%E. 60%
Consider the following reaction at equilibrium. What effect will adding more H2S have on the system? 2H2S + 3O2 ---> 2H2O +2SO2
A single pulse of a laser yields an average of 5.00 × 1018 photons with λ = 633 nm. If melting ice to water at 0°C requires 6.01 kJ/mol, what is the fewest number of laser pulses need to melt 10.0g of ice?
calculate the heat in joules released by the dissolving salt. Assume that the specific heat of the solution is the same as thar of pure water(4.184J/g- celcius) and that the calorimeter is perfect.
10 g potassium chlorate is decomposed producing oxygen gas and potassium chloride: 2KClO3 + heat -> 2KCl + 3O2. The actual yield of oxygen measures 3.915576 g. Calculate the theoretical amount of oxygen based on your starting mass of reactant.
Use Henderson Hassalbalch equation to calculate how much HCl must be added to a liter of buffer that is 1.5 M in acetic acid and 0.75M in sodium acetate to result in a buffer pH of 4.10? Ka = 1.8 x 10-5
The compound butane consists of only C and H. If 0.531g of butane is burned in oxygen and produces 1.61g of CO2 and 0.823g of H2O, what is the empirical formula of butane
If a diagnostic test starts with 15mCi of Ga-68, how much is left after the test if the test runs for 2 hr and 15 minutes?
