A total volume of 33.15-mL of 0.1053-M NaOH is needed to titrate 24.5-mL of benzoic acid. (Benzoic acid is a monoprotic acid with a pKa = 4.20). Determine the pH when the following volumes of the 0.1053 M NaOH have been added

a) 30.00 mL (before the equivalence point)?

b) 33.15 mL (at the equivalence point)

c) 36.00 mL (after the equivalence point)

NH3 is a weak base (Kb = 1.8 × 10–5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is 0.038 M in NH4Cl at 25 °C?

Calculate the pH for each of the following cases in the titration of 50.0 mL of 0.150 M HClO(aq) with 0.150 M KOH(aq). The ionization constant for HClO can be found here.

a. Use standard cell potentials to show what reaction would occur if you placed a strip of Cr in a solution of equal concentrations of NiCl2 and Al(NO3)3.

b. Zinc is plated onto iron to protect the iron from corrosion in a process called galvanization. How long would it take to plate 100g of zinc onto “sheet metal” in a ZnCl2 bath running at a current of 7.5A?

Promise to rate! Much appreciated, thank you!

You are shoveling bituminous Pennsylvania coal (with an energy content of 13,870 Btu/lb) from a coal box into a furnace. On average, with each lift and throw, you raise a 1.8 kg shovel containing 4.7 kg of coal by a height of 0.85 m. Assume your body is working with an efficiency of 15.9%. How many thousands of times more chemical energy is in the coal you move than is in the sugars and fats your body is burning to move it?

Benzene and ethylbenze are to be separated in a single-stage flash vessel. The resulting liquid stream must have a composition of x₁= 0.35 and the resulting vapor stream must have a composition of y₁= 0.75. You may assume Raoult's law applies.

a) Determine what T and P must be in the vessel in order to carry out this separation, show all work and equations used.

b) What additional information is needed to compute the relative amounts of liquid and vapor leaving the vessel?

Calculate the pH of each of the solutions and the change in pH to 0.01 pH units caused by adding 10.0 mL of 2.05-M HCl to 570. mL of each of the following solutions.

After mixing = 1.45

b) 0.135 M C₂H₃O₂^1-

^{Before mixing = 8.95}

^{After mixing = ?}

c) 0.135 M HC₂H₃O₂

_{Before mixing = ?}

_{After mixing = ?}

d) a buffer solution that is 0.135 M in each C₂H₃O₂^1- and HC₂H₃O₂

_{Before mixing = ?}

_{After mixing = ?}

I've tried this so many times and I don't understand it. Is there a formula or a set of formulas for this ?? Can someone please just spell it out for me step by step and why. Please and thank you!

If a solution containing 39.544 g of mercury(II) perchlorate is allowed to react completely with a solution containing 13.180 g of sodium dichromate, how many grams of solid precipitate will be formed?

How many grams of the reactant in excess will remain after the reaction?

When a bicyclic (or even polycyclic) compound such as ß-Naphthol is being brominated via EAS, how do I determine the locations on the molecule that will be substituted with bromine in the final product. This has to do with resonance structures of the molecule and O/P vs M directing effects of the substituent already on the ring before bromination. I'm just having trouble making the connection. Does it differ in any way compare to a molecule with only one ring, like phenol? An example and clarification would be great! Thanks!

What is the % yield of the reaction making 4.9 g of acetyl salicylic acid from 6.6 g of salicylic acid, 6.4 mL of acetic anhydride (density 1.082), and 10 drops 85 % weight phosphoric acid (density 1.685)? Molecular weights: Acetylsalicylic acid=180g salicylic acid=138g acetic anhydride= 102g

The reaction

2NOCl(g)=2NO(g)+Cl₂(g)

comes to equilibrium at 1 bar total pressure and 227C when the partial pressure of the nitrosyl chloride, NOCl, is 0.64 bar. Only NOCl was present initially. (a) Calculate delta_rG^o for this reaction. (b) At what total pressure will the partial pressure of Cl₂ be at 0.1 bar?

Consider the titration ofa 25.0 mL solution0.150 M HF with 0.150 M NaOH. What is the pH of the solution before addition of titrant, after addition of 10.0mL, and after addition of 25.0mL of titrant?
