Explain how society depends on the accuracy and precision of measurements for products sold by the retail industry, such as a gallon of gasoline, a bushel of corn, or a liter of bottled water.
What is the purpose of washing the alkyl halide with aqueous sodium bicarbonate (NaHCO3)? Write the reactions that are expected to occur when the sodium bicarbonate is added to the test tube. Why is it important to add the sodium bicarbonate slowl..
Derive the activation energy for the reaction that has a rate constant of 3.5 x 10^-5 s-1 at 25C and the rate constant of 4.8 x 10^-4 s-1 at 45C.
8 ml of the HCl was used to titrate the pK_a 3.8 group; so 2 ml was enough to titrate the rest of the high pK_a group. The upper pK_a group must have begun the experiment as 80% acid form, 20% base form.
Calculate how many grams of Copper II carbonate are obtained when 5.2ml of an 3.0M aques solution of sodium carbonate is mixed with 10.0ml of a 5.0M aques solution of Copper II Nitrate.
Amino acids with an additional COOH group in the side chain are called acidic amino acids.
What value do you get for E using the Nernst Equation? The equation is E standard = -RT/nFln[1/Cu]. The values to plug in are E = 0.340 - (8.314*298)/(2*96500)ln[1/0.10]. I calculated E = 0.31044 V. Is this correct. Any help appreciated
The composition of a gas on a dry basis is 71.0 mole% N2, 12.0% O2, 12.0% CO2, and 5.0% CO. If the mole fraction of water is 0.160, what is the gas composition on a wet basis?
