A steady current of 1.00 A is passed through an electrolytic cell for 1380sec. Explain what weight of chromium will be deposited in a cell containing 1 micromolar Chromium(IIII)nitrate as well as a chromium anode as well as a platinum cathode.
Draw a free energy profile for a reaction S to P that proceeds through a single transition state with Delta G knot equal to +2.8 kcal/mol and delta G double dagger equal to 14 kcal per mole. Label the appropiate difference.
If 45.0 mL of ethanol (density=0.789 g/mL) initially at 9.0 C is mixed with 45.0 mL of water (density=1.0 g/mL) initially at 28.6 C in an insulated beaker, and assuming that no heat is lost, what is the final temperature of the mixture
what is the number of bond pairs and shapes of c2h4 c2h6 and
The experiment all you observed rate law is rate =k [NO]^2 [Br2]. Show this mechanism is valid by deriving the rate law expression and showing that it is equal to the experimentally observed rate law
a 6.0-g sample of [Ni(H2O)6]Cl2 is dissolved in aqueous solution. If an excess of ethylenediamine (en) is added to the solution, solid [Ni(en)3]Cl2*2H2O forms. What is the theoretical yield of product from the reaction?
A titration of 200.0 mL of 1.00 M H2A was done with 1.10 M NaOH. For the diprotic acid H2A, Ka1 = 2.5 × 10-5, Ka2 = 3.1 × 10-9. Calculate the pH after 600.0 mL of 1.10 M NaOH have been added.
A gas containing only CH4 and N2 is burned with air yielding a flue gas that has an Orsat analysis of CO2:8.7%, CO: 1.0%, O2:3.8%, and N2:86.5%. Calculate the percent excess air used in combustion and the composition of the CH4-N2 mixture.
What is the pH of the solution if [OH-] of an ammonia solution is 1.0 X 10-2M?
Suppose Precipitation of the mononitration product of bromobenzene prevents dinitration from occurring. Define how this experimental result is an application of the Le Chatelier principle.
Calculate the number of grams of sulfuric acid in 1 gallon of battery acid if the solution has a density of 1.33g/mL and is 38.9\% sulfuric acid by mass.
Which atom has the least attraction for the electrons in a bond between that atom and an atom of hydrogen?
75.0 ml of a solution1.40 m is diluted to a volume of 278 ml. a 139-ml portion of that solution is diluted using 111 ml
