The reaction converting glycerol to glycerol-3-phosphate is energetically unfavorable by 9.2kJ. The reaction of ATP with water to yield ADP, hydrogen phosphate ion, and hydrogen ion is energetically favorable by 30.5kJ. These reactions are coupled so that the overall process is energetically favorable. What is Delta G for the overall process?
C3H8O3 (density=1.26 g cm-3) is added to a kilogram of water. What is the mole fraction C3H8O3 in the solution?
A 0.00400 mole sample of 2-chloro-2-methylpropane is added to 500 mL of water, and the mixture is stirred until the pH levels off. What is the pH of the solution.
What if you did the extraction 3 times 3. What if you just used 45 mL of ether in one big extraction. Why isn't this better
Under these conditions, how long would it take for a sample to decompose to 25% of it original concentration?
Specify the number of possible isomers of Trinitrophenol. Abbreviate ortho (o), meta (m) and para (p).
How long will it take in minutes until 42% of the original NO2 remains if the rate constant is 0.0066L/(mol sec) and the initial amount of NO2 is 0.45 mol/L?
A gas mixture is made by combining 7.9 g each of Ar and Ne and an unknown diatomic gas. At STP the mixture occupies a volume of 18.73 L.
Calculate the equilibrium constant (Keq) for the reaction of equimolar amounts of acetophenone and sodium hydroxide to generate the enolate.
To change the equilibrium constant from Kp to Kc, the value of RT at room temp. (25'C) you would have use is:
When the gases diydrogen sulfide and oxygen react, they form the gases sulfur dioxide and water vapor. A: Express the answer as a chemical equation. Identify all of the phases in the answer. Balance the equation
A mixture is formed from 5.0 mol of liquid benzene and 5.0 mol of liquid toluene at 25 oC and 1 atm. Assume that the mixture is ideal. Use ?Gof (benzene,l) = 90.0 kJ/mol, ?Gof (toluene,l) = 100.0 kJ/mol,
