For each reaction, identify the acid-base conjugate pairs. Then rank all reactions in order of increasing tendency for the reaction to go to completion (to the right).
a) CH3COO- + HCN <=> CH3COOH + CN-b) CH3OH + Br- <=> CH3O- + HBrc) HSO4- + NH3 <=> SO4^2- + NH4+d) HClO4 + CH3NH2 <=> ClO4- + CH3NH3+
You need to produce a buffer solution that has a pH of 5.38. You already have a solution that contains 10. mmol (millimoles) of acetic acid.
What type of hybridization is used on the central atom in CHCL3?
Hydrogen peroxide (H2O2) decomposes according to the equation H2O2(l) ? H2O(l) + (1/2)O2(g). Calculate Kp for this reaction at 25oC. (Ho = -98.2 kJ/mol, So = 70.1 J/K•mol)
Calculate the % yield of Al2(SO4) from the reaction: 2Al(OH)3(s) + 3H2SO4(aq) -> Al2(SO4)3(s) + 6H2O(l) given that 205 g of Al(OH)3 react with 751 g of H2SO4 to yield 252 g Al2(SO4)3.
How many grams of dry NH4Cl needed to be added to 1.50L of a 2.00M solution of ammonia NH3 to prepare a buffer solution that has a pH of 8.60?
The activation energy for the following reaction is 60. kJ/mol. Sn2+ + 2Co3+ → Sn4+ + 2Co2+ By what factor (how many times) will the rate constant increase.
a rigid container is filled with liquid acetone at 20 degrees C and 1 bar. through heat transfer at constant volume, a pressure of 100 bar is generated
Xenon gas is released during a certain chemical reaction and pushes back the atmosphere with a change in volume of the vessel (it has a movable piston) from 2 to 20 Liters. Calculate the work done by this release of gas.
Dust falls on Chicago at a rate of 65mg m-2 day-1. Major metallic elements in the dust include Al, Mg, Cu, Zn, Mn, and Pb^5. Pb accumulates at a rate of 0.03mg m-2 day-1. How many metric tons
The standard potential of the Cell Pt|H2|HBr|AgBr|Ag was found to be +0.07372 at 293 K and +0.06873 at 303 K. Evaluate the standard reaction Gibbs energy, enthalpy, and entropy
Nitrate ion (NO2)^(-1) can be analyzed by creating an acidic solution of nitrite ion and adding excess iodide (I)^(-1) ions creating NO and I2. The I2 combines with excess (I)^(-1) to create (I3)^(-1).
