Question- You are asked to go into the lab and prepare an acetic acid-sodium acetate buffer solution with a pH of 4.30 +/- 0.02.
1) What molar ratio of CH3COOH to CH3COONa should be used?
Explain each and every step in detail. I need proficient help in the above problems.
Assuming the same calorimeter constant you determined (I got 217.8 J/degreesC) and assuiming NaOH is the limiting reagent, what is delta H(neutralization) in kJ/mol?
Given the same reactant concentrations, the reaction CO(g)+Cl2(g)------COCl2(g) at 251 degrees celsius is 66.9 times as fast as the same reaction at 165 degrees celcius. Calculate the activation energy for this reaction
Acyl chloride can hydrolyze in water spontaneously to carboxylic acid. In the interfacial polymerization water is used as one of the solvent, why you don't have to worry about the hydrolysis of sebacoyl chloride in this action
A biochemical engineer isolates a bacterial gene fragment and dissolves a 14.0 mg sample of the material in enough water to make 34.5 mL of solution. The osmotic pressure of the solution is 0.340 torr at 25°C.
how many moles of C3H8 need to react to release 5280 kJ of energy?
What type of error is this associated with the concentration of Cu2+ and why is it so? what is the concentration (in mole/L or M) of Cu2+ and NO3- in the final solution
a gas occupying a volume of 428 ml at a pressure of 0.970 atm is allowed to expand at constant temperature until its
A particular natural gas consists, in mole percents, of 83.0% CH4 (methane), 11.2% C2H6 (ethane), and 5.80% C3H8 (propane). A 385-L sample of this gas, measured at 21C and 739 mmHg, is burned in an excess of oxygen gas.
Is the dissociation of NaCl reversible. When you dissolve it in water does it dissociate and associate back together
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
what is the ph at the equivalence point in the titration of 10.0 ml of 0.51 m hz with 0.200 m naoh? ka 5.1 times 10-6
4Al + 3O2 = 2Al2O3 determine the percent yield if 124 g Al2O3 are produced when 3.0 moles of Al are reacted
