Consider a galvanic cell based on the reaction
2Fe2+(aq)+Cl2(g)→2Fe3+(aq)+2Cl-(aq)
Calculate the cell potential at 25°C when [Fe2+] = 1.8 M , [Fe3+] = 1.0×10-3 M , [Cl-] = 2.1×10-3 M , and PCl2 = 0.39 atm.
How will not knowing the difference between elements, compounds and mixtures have an affect on the concepts of organic chemistry? Why is it important to understand the concept behind elements, compounds and mixtures to succeed in organic chemistry?
Combustion of 25.0 g of a hydrocarbon produces 85.9 g of CO2. What is the empirical formula of the compound?
Why is it not possible for the molar mass of a monoprotic acid to have a value less than 1g/mol

Find out the eq molar concentration of SCN- in the system.( Kc=[FeNCS2+]/[Fe3+][SCN-] =271.5)
A 23.45g piece of iron and a 29.95g piece of gold at 100.00C were dropped into 530ml of water at 16.05C. The molar heat capacities of iron and gold are 25.19 (j/mol x C) and 25.41 j/(mol x C). respectively. What is the final temperature of water a..
A mole of CH4 expands reversibly from 1 to 50 L at 25 degrees Celsius. Calculate the work in Joules assuming 1) the gas is ideal and 2) the gas obeys the van der Waals equation. For CH4 (g), a = 2.283 L^2 bar mol^-2 and b = 0.04278 L mol^-1
If you look at a reaction equation for an esterification reaction, you cannot tell where the oxygen comes from (acid or alcohol). Knowing the mechanism of this reaction, devise an experiment using O18, to help prove unequivocally where the oxygen ..
At 293K, the time of flow for water through a viscometer is 342.5 s; for the same volume of an organic solvent, the time of flow is 271.4 s. Calculate the viscosity of the organic liquid relative to that of water. The density of the organic solven..
Most organic polymers are named based on the monomers used in their production. However, poly(vinyl alcohol) (PVA) is not made from vinyl alcohol,
