100.0 mL of 0.100 M acetic acid is placed in a flask and is titrated with 0.100 M sodium hydroxide. An appropriate indicator is used. Ka for acetic acid is 1.7 x 10^-5. AFTER 25.0 mL of NaOH is added, what is the pH in the flask at the following points in the titration?
how many grams of carbon dioxide are produced when 23.5 g of propanal react with excess oxygen in a combustion reaction
calculate the percent yield for an experiment in which 5.50 g of socl2 was obtained in a reaction of 5.80 g of so2 with
A bomb calorimeter with an insulating heat capacity is used to burn 5.682g of a chocolate candy bar. If the 1.00kg of water in the calorimeter then increased from 18.0220C to 56.1250C, what is the U for the chocolate in kJ/g chocolate
What IR peaks of your cyclohexanone product are characteristic of the ketone group? What IR peaks of cyclohexanone will indicate it is impure? for a carboxylic acid, such as adipic acid?
Predict that it was dissolved in HCl then mixed into the diethyl ether because diethyl ether is a base and since the benzoate contains an amine group they would remain unreactive with one another.
although even more strained than cyclopro-panone, is nevertheless quite stable and can even be distilled. Explain, taking the polarity of the carbonyl group into account.
At a given temperature, 2.74 atm of F2 and 2.08 atm of Br2 are mixed and allowed to come to equilibrium. The equilibrium pressure of BrF is found to be 1.003 atm. Calculate Kp for the reaction at this temperature. F2(g) + Br2(g) 2 BrF(g)
