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 when the temperature is raised from 10°C to 28°C (R = 8.314 J/mol • K)?
in the reaction P4+5O2->2P2O5, how many moles of oxygen are consumed each time 0.500 mole of P2O5 is formed?
Determine the theoretical yield and percent yield if 21.8g of K2CO3 is produced by reacting 27.9g KO2 with 29.0L of CO2 (one mole of CO2 occupies 22.4L). The GFW (KO2)= 71.10 , GFW (K2CO3)= 138.21 , GMW (CO2)= 44.01
The following reaction takes place in a sealed 40.0-L container at a temp of 120 degrees C 4NH 3(G) + 5 O2 (g) --> 4NO (g) + 6H2O (G)
A solution of acetic acid, HC2H3O2, on a laboratory shelf was of undetermined concentration. If the pH of the solution was found to be 2.39, what was the original concentration of the acetic acid? ___M
which one is oxidizing agent and which one is reducing agent?
How would I do that? I have a diagram for a trigonal bipyramidal crystal field and two values are on the diagram. There's a delta 0.19 and a delta 0.79.
This indicates that the unknown material is a pure compound? Not be a pure compound, suggest an alternate procedure to verify the purity of the sample
The boling point of water in city a is 94 degrees celcius and in city b it is 97 degrees celcius. which is at the higher elevation.
The relationship of [A]t / [A]o = 0.50^n, where n=number of half lives. n = I understand that the linear plot of 1/[C4H6] means second order.. but i do not understand how to calculate the half life from this information for part b.
Using 1M aqueous HCl, 1M aqueous NaHCO3 and 1M Aqueous NaOH, could you separate an ethereal solution of benzoic acid and salicylic acid. If so, provide a flow chart indicating how; if not, explain why.
calculate the pH of a 0.10M solution of hypochlorous acid. ka for hypochlorous acid is 3.5x10^-8
What is the freezing point of water under a pressure of MPa? Assume that the density of ice is 0.915 g.cm^-3 and that of liquid water is 0.998 g cm^-3 at this pressure
