Need help with my homework, questions regarding to a protein named Glutamate dehydrogenase.
An aqueous solution of calcium hydroxide is standardized by titration with a 0.129 M solution ofhydrochloric acid. If 27.9 mL of base are required to neutralize 17.7 mL of the acid, what is the molarity of the calcium hydroxide solution?
Write a net ionic equation to explain why the pH didn't go up to about 10, as it would have if that amount of NaOH were added to distilled water or to 20mL 0.00040 M HCl, which also would have a pH of 3.40
Problem- Enough of a monoprotic acid is dissolved in water to produce a 0.0123 M. The PH of the resulting solution is 2.58. Calculate the Ka for the acid.
The student then adds 5 mL of an unknown volatileliquid and heats the flask in a boiling water bath at 99.2C(degrees) until all liquid disappears. The flask, foil, andunknown after heating that is dry and cool weigh 50.610 g.
Calcium hydroxide reacts with carbon dioxide to form calcium carbonate. The reaction for this process is: Ca(OH)2(s) + CO2(g) ? CaCO3(s) + H2O(g), ?H = -69.1 kJ What is the enthalpy change if 380 g of calcium carbonate is formed
40.0 ml of an acetic acid of unknown concentration is titrated with 0.100 M NaOH. After 20.0 mL of the base solution has been added, the pH in the titration flask is 5.10. What was the concentration of the original acetic acid solution. (Ka(CH3COO..
Baseball reporters say that long fly balls that would have carried for home runs in July "die" in the cool air of October and are caught. The idea behind this observation is that a baseball carries better when the air is less dense. Dry air is a m..
Given that the vapor pressure of pure n-hexane and pure h-heptane at 25 °C are 151.4 mmHg and 45.62 mmHg respectively, calculate the total vapor pressure above a solution containing only n-hexane and n-heptane in which the mole fractio n of n-hexa..
The formation constant Kf for the complex ion Zn(OH)42- is 2.8 1015. What is the concentration of zinc ion, Zn2+, in a solution that is initially 0.50 M in Zn(OH)42-
Consider the following equalibrium: 4NH3(g) + 3O2(g) 2N2(g) + 6H2O(g). Suppose 0.30 mol of NH3 and 0.40 mol of oxygen are added to a 5.0-l container. If x mol of water is present at equalibrium, how many moles of ammonia will remain at equalibri..
A 1.70-g sample of a large biomolecule was dissolved in 14.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C.
you have two neutral solutions. one contains the indicator methyl red which turns red in strongly acidic aqueous
