If Ka is 1.85 x 10^-5 for acetic acid, calculate the pH at one half the equivalence point and at the equivalence point for a titration of 50 mL of 0.100 M acetic acid with 0.100 M NaOH.
If the metal crystallizes in a body-centered cubic structure, which choice is closest to the atomic mass?
The values of delta h and delta s for the reaction CaCo3(s) yields CaO(s)+CO2(g) are 177.8kJ and 160.5 J/K respectively. the pressure of CO2 at equilibrium for the process
There are two carboxylic acid functions in 3-nitrophthalic acid. The pKa of the acid function is at the 2-position is approximately 2, whereas that at the 1- position is about 3. Which of the two is the more acidic and why

The contents of one 40-lb bag of topsoil can cover 10.0 square feet of ground to a depth of 1.0 in. How many bags are needed to cover a plot that measures 200.0 meters by 300.0 meters to a depth of 4.0 cm?
Calculate the steric strain for the most stable chair conformer and for a less stable conformer for the following: a) trans-1-ethyl-3-fluorocyclohexane
Calculate the pH of the acid solution before any NaOH has been added. Calculate the pH of the analyte after 10.00mL of 0.100 M NaOH has been added. Calculate the pH of the analyte of the equivalence point? Calculate the pH of the analyte after add..
The normal boiling point for H2Se is higher than the normal boiling point for H2S . This can be explained by
Consider a different titrant for this exercise. Suppose Ca(OH)2 were used as the titrant, instead of NaOH. This will make the titrant twice as concentrated in hydroxide ion. The analyte will still be HC2H3O2.
