Butanoic acid, CH3CH2CH2 COOH, is a weak acid. Which of the following would be the pH of a 0.01 M butanoic acid? the answer is > 2.0, but how would I figure that out?
The alcohol content of hard liquor is normally given in terms of the "proof," which is defined as twice the percentage by volume of ethanol (C2H5OH) present. Calculate the number of grams of alcohol present in 1.00 L of 90. proof gin. The density ..
The pH would decrease slightly. The pH would decrease dramatically. The pH would increase slightly. The pH would increase dramatically. The pH would not change at all.
Find delta E, delta H, q, and w for the change in state of 1.0 mol H2O(l) at 84 degree C to H2O(g) at 109 degree C. The heat capacity of H2O(l)= 75.3 J/molK, heat capacity of H2O(g)= 25.0 J/molK, and the heat of vaporization of H2O is 40700 J/mol ..

In the emission spectrum of helium, there are strong lines at wavelengths of 447.1 nm, 501.6 nm, and 587.6 nm. Using the Balmer-Rydberg equation, determine the values of nf for each emission.
NH3 is a weak base (Kb=1.8 x 10^-5) and so the salt NH4Cl acts as a weak acid. What is the PH of a solution that is 0.049 M in NH4Cl?
How many grams of NH3 can be produced from the reaction of 28 grams of N2 and 25 g of H2
How many L of H2 gas (at STP) is produced from 470 mL of 0.36 M HCl and excess Zn? The reaction is: Zn + 2HCl = ZnCl2 + H2
aluminum oxide al2o3 is a widely used industrial abrasive corundum emery with its specific application depending on the
A 0.1019g portion of an aspirin tablet was dissolved in sufficient water to prepare 1.000L of solution. A pipet was used to transfer 10 mL of the solution to a 100 mL volumetric flask. A 2 mL portion of 4 M NaOH (aq) was added to the flask, and th..
