b. butanoic acid from 1-butanol
what volume of nitrogen gas is needed to react completely with 150.0 L of hydrogen in the production of ammonia.
Describe the titration curve for the titration of a weak base with a strong acid. Indicate the chemical reaction, the points that correspond to the equivalence point, the pH = pKa and the region with maximum buffering.
What is the buffer component ratio, ([CH3CH2COO-]/[CH3CH2COOH]) of a propanoate buffer that has a pH of 4.49. Ka of CH3CH2COOH is 1.3 x 10-5.
The family estimates that it will take an average of 21 GJ of energy per month to keep the house heated to this temperature for 5 cold months. The cost of electrical energy is $0.185/kWh (kilowatt-hour).
