Determine the pH of the solution containing 8*10^(-3) M each of HF and NaF. Assume that NaF dissociates completely. Acid Dissociation constant for HF is Ka=6.3*10^(-4).
the labels of bottles that contain barium hydroxide, hydrochloric acid and sodium carbonate had fallen off. When the contents of the bottle A were mixed with B's Contents, a white precipitate formed, A with C yielded a gas and B with C gave heat.
What is the mass of sugar in 735g of a 19.85% sugar solution?
What is the initial concentration (in M) when 19 mL of a iron(III) chloride solution was diluted with 18.5 mL of solvent to a final concentration of 0.576 M? Assume the volumes are additive.
the reaction conditions are influencing the directing effect of the -NH2 group. Explain why this occurs, using both words and structures.
Write a reaction mechanism for the reaction of (Z) 3-methyl-3-hexene with Cl2 and H2O. Use curved arrows to show electron movements and clearly show the structures of the reaction intermediates and the final product.

An exothermic reaction liberates 7.58 kJ of heat in a coffee cup calorimeter containing 157 grams of solution. The temperature of the solution in the calorimeter increases by 11.2°C. How much heat was absorbed by the calorimeter? Assume the specif..
sulfur dioxide is an unwelcome result of burning soft coal in power plants. Some of the sulfur dioxide ends up as sulfuric acid ( H2SO4) in acid rain.
When titrating a standardized solution such as NaOH, why is it important to perform each titration multiple times think about why it's important to continue titration past the equivalence point.
Describe the experiment(s) (as necessary), observations (as necessary), and results (as necessary) which would allow you to distinguish between
A chloroform-ethanol solution at 35 oC with ?ethanol=0.200 in the liquid phase has a vapor pressure of 304.2 torr and a vapor composition of Yethanol= 0.138. Calculate the activity and activity coefficient for ethanol in this solution
