You did a reaction and it resulted in the following mixture of compounds:

(Benzoic ring, benzoic ring with OH, Benzoic ring with COOH)

What would you do to isolate and then purify benzoic acid?

How would you prove that your final product is pure?

Which peaks in the IR and NMR you would look for to see if you got indeed benzoic acid? Mention all, but also specify the peaks that are different from peaks the other compounds have as well.  

what is the pH of a solution following the combination of 245.0 mL of a 4.00*10^-3 M NaOH solution with 255.0 mL of a 2.33*10^-3 M H2SO4 solution?

100 moles of ethane (C₂H₆) are burned with 50% excess air. The percentage conversion of the ethane is 90%; of the ethane burned, 25% reacts to form CO and the balance reacts to form CO₂. Calculate the molar composition of the stack gas on a dry basis and the mole ratio of water to dry stack gas.

Define ΔGO, ΔGO’, ΔG, and ΔG‡

The Ideal Gas Law and Stoichiometry The industrial production of nitric acid (HNO3) is a multistep process. The first step is the oxidation of ammonia (NH3) over a catalyst with excess oxygen (O2) to produce nitrogen monoxide (NO) gas as shown by the unbalanced equation given here: ?NH3(g)+?O2(g)→?NO(g)+?H2O(g)

Part A What volume of O2 at 912 mmHg and 33 ∘C is required to synthesize 16.0 mol of NO?

volume of O2 = 419 L

Part B

What volume of H2O(g) is produced by the reaction under the same conditions? Express your answer to three significant figures and include the appropriate units. volume of H2O =

Calculate the concentrations of all species in a 1.49 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4× 10–2 and Ka2 = 6.3× 10–8. [Na+]= [SO3^2-]= [HSO3^-]= [H2SO3]= [OH^-]= [H^+]=

One turn of the CAC only produces one ATP (or GTP). Explain how most of the energy of the four oxidation steps in the CAC is conserved?

Please help explain and where could I find more information on this

If the K_a of a monoprotic weak acid is 8.2

five thousand kilograms of coal/h is combusted with 3000 kg mol of air/h. assume the following reaction:

C+O -> CO₂

2H+ 1/2 O₂-> H₂O

S+O₂-> SO₂

C+1/2 O₂->CO

the ultimate analysis of coal reveals it contains 0.75 kg C / kg;0.17 kg H / kg; 0.02 kg S / kg; 0.06 kg ash / kg. Calculate precent excess air supplied?

Find the pH during the titration of 20.00 mL of 0.1000 M butanoic acid, CH3CH2CH2COOH (Ka = 1.54 × 10−5), with 0.1000 M NaOH solution after the following additions of titrant. (and the answer is not 4.81)

(b) 20.10 mL:

pH =

under a certain set of conditions the solubility of Ag2CO3 is 3.5x10^-2 g/L. what is the ksp?

Use orbitals to explain why bond rotation is possible around the single C‐C bonds in this molecule but not the double C=C bond. Note: To answer this question you may need to review prerequisite topics you covered in first‐semester general chemistry. Specifically, concepts about orbitals and bond formation should be reviewed (sigma bonds, pi bonds, s orbitals, p orbitals, etc.).

A solution contains: silver, lead (II), bismuth (III), antimony (III), nickel (II), and zinc. prepare a flow chart to show how you would separate and identify the six ions in this solution.

In an experiment similar to this one, and done very carefully so that the yield was essentially 100%, 0.05 g of iron reacted with hydrochloric acid to give 0.145 g of a chloride FeCln. There are two chlorides of iron, ferrous chloride, FeCl2, and ferric chloride, FeCl3. Which one was obtained?

Describe how a fluoride selective ion electrode measures the fluoride ion concentration and explain why the potential approaches 0 at high concentrations
