Why would a galvanic cell made of different concentrations of the same ion/metal solution have a non zero initial voltage?
determine the reduction potential of the left and right sides of the cell using the Nernst equation with the standard reduction potential (E°) and given ion concentrations. Then using the sign of the cell potential, determine if the the reaction w..
An initial reaction mixture contains 9.42 g of Fe and 8.50 g of S. The following reaction occurs:
Assume a weather balloon is a perfect sphere with radius, r=3m. Archimede's principle states that if something is less dense than air it will rise until its density is equal to the density of air it displaced. Assume air is 80% nitrogen and 20% ox..
Chemically equivalent amounts of ferric and stannic ions, iron(III) and tin(IV) respectively, are mixed in solution. Calculate the redox potential.
You have 200ml of a solution which is 0.2M NH3 and contains 0.23grams of NH4Cl. a. What type solution is it? b. What is the pH of the solution
When a 9.15-g sample of solid ammonium nitrate dissolves in 58.4 g of water in a coffee-cup calorimeter (see above figure) the temperature falls from 21.00 oC to 10.88 oC. Calculate H in kJ/mol NH4NO3 for the solution process. NH4NO3(s) NH4+(aq) +..
Determine the molar mass of hydroxyquinoline and the uncertainty associated with the molar mass. Report the absolute uncertainty in the molar mass in your final answer.
A gaseous compound containing carbon and hydrogen was analyzed and found to consist of 83.65% carbon by mass. What is the empirical formula of this compound
Describe the characteristics of a neutralization reaction, how it is identified, and types of compounds in the reactants and products. Please provide an example
At a certain temperature and pressure 4.2 L of N2 reacts with 6.3 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure, will be produced? (L)
The goal of the treatment facility is to lower the concentration of iron to 0.3 mg/L by precipitation. What hydroxide concentration is necessary to obtain this result? What would the pH be for that concentration
Na+ cations have been successfully trapped into such capped carbon nanotubes. Explain what the frequency for the transition is between the two lowest energy states for a Na+ cation trapped in a CNT 2.0 cm long
