Based on the steps occurring in an acid-base reaction, which definition of acids and bases is most practical?
Why isn't HBrO a stronger acid than HBr. Doesn't the acid strength increase with the amount of oxygens.
If two liquids A and B that both boil at 100 ºC when pure form a non-ideal, positively deviating solution, what will be the boiling point for a 50:50 mixture of A and B?
A 80.0 mL volume of 0.25 M HBr is titrated with 0.50 M KOH. Calculate the pH after addition of 40.0 mL of KOH.
When the nuetron to proton ratio in a raditoactive isotope is higher than that required for stability, it main gain greater stability by emitting
the decomposition of hypothetical compound X from part A is 1.60 M -1 * min -1, calculate the concentration of X after 16.0 min. Initial concentration is o.467
Experiment ClO2 (M) OH (M) Rate (M/s) Determine the rate law expression and calculate the value of the rate of constant.
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/..
An iron ore sample is a mixture of Fe2O3 and several impurities. A 752. g sample of the impure iron ore is heated with excess carbon.
M.r eric castilo purchased alot for PH 1300000 and sold them 2 years later for PH1900000. At what rate did his money earn?
The standard free energy of activation of a reaction A is 76.8 kJ mol%u20131 (18.4 kcal mol%u20131) at 298 K.
Nitrogen dioxide (NO2) cannot be obtained in a pure form in the gas phase because it exists as a mixture of NO2 and N2O4. At 25°C and 0.98 atm, the density of this gas mixture is 2.7 g/L.
Consider the flask apparatus in the following diagram, which contains 2.00 L of H2 at a pressure of 380. torr and 1.00 L of N2 at an unknown pressure. If the total pressure in the flasks is 300. torr after the stopcock is opened, determine the ini..
