When an aqueous NaCl solution is electrolyzed, how many faradays need to be transfered at the anode to release .100 mol of Cl2 gas
A common reaction is when two polyatomic ions or compounds of the same element in water combine to form a single chemical with an intermediate oxidation state - this called a comportionation reaction.
A 0.456 gram sample of an unknown monoprotic acid (let's call it HZ) was dissolved in some water . Then the acidic solution was titrated to the equivalence point with 32.5 mL of 0.174 M KOH.
for a particular redox reaction MnO2 is oxidized to MnO4- and Ag+ is reduced to Ag write a balanced equation
Consider the following reaction. N2 + 3H2 ->2NH3 . 28.0 grams of N2 and 5.04 grams of H2 are reacted, producing 17.8 grams of NH3. What is the percent yield?
Which solvent displayed the strongest propensity to encourage keto-enol tautomerization. CHCl3, DMSO, CH3OH? Or does this propensity more closely follow the type of solvent it falls under (such as nonpolar, polar aprotic, or polar protic).
A phase change occurs at 298 K and deltaS system - -13.5 J/K. What is the change in the entropy of the surroundings?
Then 40.0 mL of this solution were titrated with 0.060 M HClO4. Calculate the pH at the first equivalence point.
Find the vapor pressure of a solution that contains 218 g glucose in 460.0 mL of water at 30 degrees Celcius.
A 10.80-mL sample of sulfuric acid from an automobile battery requires 35.18-mL of 1.62 M sodium hydroxide solution for complete neutralization. What is the molarity of the sulfuric acid? Sulfuric acid contains two acidic hydrogens.
estimate the volume of 5 M NaOH must be added to adjust the pH from 4 to 9 solution of 100mL 100mM phosphoric acid
Determine the mass of CO_2 produced by burning enough carbon (in the form of charcoal) to produce 490 kJ of heat.
how would each of the following change the rate of the reaction shown here? 2NO(g) + 2H2(g) > N2(g) + 2H2O(g)? a)adding NO(g). b)lowering the temperature. c)removing some H2(g) d)adding a catalyst
