How did the labour theory of value permit David Ricardo to focus on forces affecting the accumulation of capital? Discuss

How does the closest H-H distance between hydrogens on C1 and hydrogens on C4 of gauche butane compare to that for the 1,3-diaxial methyl-hydrogen distance in axial methylcyclohexane. How is this reflected in the respective ΔG values from questions 1 and 2?

What is the mass of 6.3 mol of CO?

MsbA is an ABC transporter that transports LPS from the cytoplasmic to periplasmic leaflet of the inner membrane of E. coli (flipase).

A) Diagram the basic mechanism how this ABC transporter would transport LPS across the membrane.

B) You have isolated a variant of MsbA that has the Q-loop mutated from a Q to a V. How do you think this will affect the function of MsbA?
Design a set of experiments to test your hypothesis and explain what you expect to observe.

0.15 M = ( m / 104.1) x ( 1000 / 50.0 mL) Please help solve, looking for m which represents mass from the following question. I am not sure how to solve for m here, I know the answer is 0.781g but I'm not sure how to find that.

Q: How many grams of malonic acid are needed to make 50.0mL of 0.15 M malonic acid and how many grams of MnSO4 X H2O are needed to make 50.0mL of 0.020 M manganese (II) sulfate? Show all calculations

the questions are a,b,c and d

 

b) Determine the limiting reagent. (5 marks)

 

c) Determine the mass of produced (theoretical yield). (2 marks)

 

m = n x M M

 

d) If the actual yield of was 22.3 g, determine the percent yield. (2 marks)

The titration of 42.35 mL of H2SO4 requires 21.17 mL of 0.5000 M NaOH for complete neutralization. Calculate the concentration of H2SO4. Why is the answer 0.1250 M H2SO4?

A student measured the concentration of H2SO4 by titrating it with 3 L of NH3 at 646 torr and 305 K. The experiment revealed that 144 mL of H2SO4 was required to neutralize the NH3. Calculate the concentration of the acid in terms of normality.
