The equilibrium constant for the reaction of S02 (g)+NO2 → SO3(g)+NO(g) is 3.0. Find the amount of NO2 that must be added to 2.6 mol of SO2 in order to form 1.3 mol of SO3 at equilibrium?
The heat capacity of the solid lead oxide is given by:Cp = 44.35 J/K/mol + 1.47*10^-3 T J/K^2 Calculate the change in enthalpy of 3.25 mol of PbO(s) if it is cooled from 750 K to 300 K at constant pressure
A 1.304 gram sample containing an unknown amount of arsenic trichloride and the rest inerts was dissolved into a NaHCO3 and HCl aqueous solution. To this solution was added 1.500 grams of KI and 50.00 mL of a 0.00919 M KIO3 solution.
Which the reduction reaction for elemental sulur that gains two electrons to form the sulfide ion. Write the oxidation reaction for copper metal losing two electrons to form the copper II ion.
Given the reaction of aA+bB-->cC, if "d" moles of A are combined with excess B, how much C can be formed?
Calculate the molar solubility of Fe(OH)2 in a buffer solution where the pH has been fixed at the indicated values. Ksp = 7.9 x 10-16. (a) pH 7.0 M (b) pH 11.0 M (c) pH 13.6 M
If there is no such evidence, then we have no reason to believe in witches. If there is evidence, we do have reason to believe in witches. There is no such evidence. Therefore we have no reasons to believe in witches.
Describe briefly four types of batteries. In your description, include the redox reactions
