Problem- Work the following problems for titration of acetic acid (K a=1.8x10-5) showing all work use more paper if needed.
1) Calculate the pH of a 0.150 M solution of acetic acid. This is a simple pH of a weak acid problem. Get the [H+
Here is the problem which I am struggling on please help me
Explain Oxidation of Elements and Their Reactions, Which element is oxidized and which element is reduced in each of the following reactions?
Equal quantities of 0.010M solutions of an acid HA and a base B are mixed. The pH of the resulting solution is 9.4. A) If Ka for HA is 9.0×10?5, what is the value of the equilibrium constant for the reaction between HA and B
what is the easiest way to convert grams to grams in chemistry?example calculate the number of grams of kcl that can be
Description of Balanced equations, Identify the steps involved in the formation of these compounds. Show the removal of water and the reactant.
Calorimetry is a method used to measure changes in enthalpy, or heat, that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters.
A solution contains .018 mol each of I-, Br-, and Cl-. When the solution is mixed with 200 ml of .24 M AgNo3, what is the [Ag+]? Assume no volume change.
Calculate the change in internal energy of the following system: a balloon is cooled by removing 0.651kJ of heat. It shrinks on cooling, and the atmosphere does 384J of work on the balloon.
hydrogen is collected over water, two gases are present hydrogen and water vapor.calculate partial pressure of hydrogen gas. Barometric pressure = 773.94 mmhg.
calculate the mass of propylene glycol rmc3 rmh8 rmo2 that must be added to 0.340 kg of water to reduce the vapor
To obtain the same antifreeze protection requires 76 of propylene glycol to replace each 62 of ethylene glycol. Calculate the mass of propylene glycol required to replace 7.00 of ethylene glycol.
A solution of 75.0 g of benzene (C6H6) and 75.0 g of toluene (C7H8) has a total vapor pressure of 80.9 mmHg at 303 K. Another solution of 100.0 g benzene and 50.0 g toluene has a total vapor pressure of 93.9 mmHg at this temperature.
If 4.00 g of the unknown compound contained 0.133 mol of C and 0.267 mol of H, how many moles of oxygen, O, were in the sample?
