For the reaction: Fructose 6-phosphate to glucose 6-phosphate, delta G is -0.4 kcla/mol. Starting with a 0.50 M solution of fructose 6-phosphate, what is the equilibrium concentration of both fructose 6- phosphate and glucose 6-phosphate?

Perform the appropriate calculation to determine the theoretical pH of the buffer solution after 10 drops of 0.1M HCl was added. Ka of acetic acid = 1.8 x 10-5

Using the definition of Ka and the Debeye-Huckel expression for the mean ionic activity
coefficient, calculate the pH of a 0.10 M acetic acid solution in (a) pure water (b) 0.1 M
NaCl and (c) in 0.2 M MgSO4. Assume consistent results after 3 iterations in each case

San Diego Gas & Electric provides natural gas composed of 92 mol% methane, 7.0 mol% ethane, & 1.0 mol% nitrogen. 100 mol/hr of this gas is fed to a furnace with 30% excess air. The fractional conversion of both methane and ethane is only 90% and no NOx is formed. The selectivity (CO2:CO) is 20. Using only component molar flow rates draw and label the process flow diagram, show that there are 0 degrees of freedom, and write down the appropriate equations but do not solve. Use both the molar balanxe method and atom balanxe method.

The Water Treatment Plant and the University Water Treatment Plant remove calcium hardness (Ca2+) by precipitating (making) CaCO3(s). If, after establishing equilibrium with CaCO3(s), the dissolved Ca2+ concentration is 10 mg/L and the pH is 10.5. a. What is the CO32- concentration in mol/L? b. What is the HCO3- concentration in mol/L? c. What is the alkalinity in mg/L as CaCO3?

Gold has a face-centered cubic arrangement with a unit cell edge length of 4.08 Å . How many moles of gold fit in a gold nanoparticle sheet with a length of 57.3 nm , a width of 20.1 nm , and a thickness of 10.2 nm ?

For the following reaction: H2(g) + I2(g)<--->2HI(g)     ; Kc=49.5

The beginning concentrations are: H2: 0.10M, I2: 0.050M, and HI:0

Assume this reaction is not at equilibrium. When it does reach equilibrium, what will the concentrations be?

how exactly do you determine the miller indices for the first three peaks of a diffraction pattern? for cubic it makes sense for it to be (100) (110) (111) but for less symmetrical structures how do you determine which planes will have the lowest values. Specifically for structures such as tetragonal, rhombohedral and orthohrombic.

please answer all 4 questions. I need brief and correct answers. thank you in advance.

1. Why is it important to mix the solutions after adding the reagents? How is mixing done in this experiment?

2. What is the reason for rinsing the precipitates before further testing?

3. What two things are extremely important to remember when centrifuging?

4. Why is it possible to separate Cu+2 from Al+3 and Fe+3 with NH4OH but not with NaOH? (Hint, consider solubility properties.)

please answer all 4 questions. i don't need a long answer. please explain them briefly and correctly. Thank you in advance.

1. What does the term qualitative analysis mean?

2. The confirmatory reactions that identify nitrate and nitrite both produce brown NO2 gas. What criterion will you use to determine which anion produced the gas?

3. The confirmation reaction for the halides involves the addition of chlorine water. Describe how you will know which, if any, of the anions is present.

4. A student added calcium ion, Ca+2 to an aqueous solution and observed formation of a precipitate. Addition of HNO3 had no effect on the precipitate. What anion was present in the original solution? Explain your answer.

How many milliliters of a 0.204 M HI solution are needed to reduce 24.5 mL of a 0.371 M KMnO4 solution according to the following equation: 10HI + 2KMnO4 + 3H2SO4 → 5I2 + 2MnSO4 + K2SO4 + 8H2O

In clinical chemistry, explain what Pyridoxal-5’-Phosphate is, and how does it work?

3. A pipette is used to add 46 mL of 0.1 M Pb(NO3)2 to a 294.0 mL solution of 0.2 M NaF. Determine the equilibrium concentration of Pb2+(aq) in the final solution. Ksp(PbF2)=3.6E-8

Imagine that inside a cell the [creatine phosphate] = 3.5 mM, [creatine] = 0.6 mM, and [Pi] = 4.3 mM. Furthermore, imagine that the pH inside the cell is 7.4. Given that ΔG°′ for creatine phosphate hydrolysis is -10.3 kcal/mol, what is the ΔG for creatine phosphate hydrolysis inside the above-described cell, which is at 37 °C? Report your answer in kcal/mol to the nearest tenths. Hint: you might wish to consult the chapter in our text that discusses thermodynamics.

The reaction H2(g) + Br2(g) 2HBr(g) has Kc = 2.0 x 109 at 25 °C. If 0.100 mol of H2 and 0.100 mol of Br2 were placed in a 10.0 L container and allowed to react, what would all the equilibrium concentrations be at 25 °C?
