Are we concerned with the amount of sample that we use in this experiment and list at least three pros and cons for using a small sample under 0.05g and a large sample over 2.0g
The precipitate that forms in the qualitative analysis of the chloride ions is AgCl. Calculate the mass of AgCl that should be produced when an excess of AgNO3 is reacted with 0.1900 g of [Co(NH3)5Cl]Cl2.
A gas was enclosed in a rigid-walled container. The initial temperature and pressure were 52°C and 0.55 atm, respectively. If the final pressure were 2.41 atm.
Reaction kinetics - Determination of the activation energy of the reaction between oxalic acid and potassium permanganate.
What would be the potential in volts of a standard hydrogen (S.H.E.) electrode under the following conditions?:
A reaction with the activation energy Ea= 153.00 kJ/mol, has a rate constant k = 6.400 x 10(-4) at 364.00 Kelvin. Determine the temperature required to increase the rate constant 5 times . R = 8.314 J K-1mol-1
What is the rate of entropy generation within the tank? 3.) If we duplicated the stream conditions (temperatures, pressures, and flowrates) with an internally reversible process, what is the maximum rate at which work could be obtained?
Consider the reaction Pb(s) + 2H^+(aq) ? Pb^2+(aq) + H2(g). If the hydrogen gas pressure is maintained at 1.00 atm and the lead(II) ion concentration is 0.025 M, find the pH at which this reaction is at equilibrium
Calculate the solubility (in M units) of ammonia gas in water at 298K and a partial pressure of 6.50bar . The Henry's law constant for ammonia gas at 298K is 58.0 M/atm
With Niemann-Pick Disease, discuss how lipid metabolism is affected, particularly which enzyme(s), and how the body is affected
the temperature derivative of the entropy at constant pressure is related to what important,measurable physical quantity? Can this quantity ever be negative?And also recall how the curvature of a surface is related to the sign of a certain derivat..
A solution is initially 0.050M in acetate, CH3COO- (Kb = 5.6 x 10^-10). 10.0mL of 0.10 M HCl is added. Calculate Ka for the conjugate weak acid of CH3COO-
enough solid KHT be added to the kcl-nacl solution to ensure that some solid remain undissolved after 20 minutes stirring?
