Draw every stereoisomer for 1,2-difluoro-1,2-dimethylcyclopentane. Use wedge-and-dash bonds for the substituent groups, and be sure that they are drawn on the outside of the ring, adjacent to each other. The skeletal structure of one molecule is included to indicate the proper format; modify the X\'s on the given structure to create the first stereoisomer.
If 49.0g of H3PO4 is reacted with excess KOH, determine the percent yield of K3PO4, if you isolate 49.0g of K3PO3.
How much heat is released to the surroundings when 1.5 moles of water cools from 150 to 20 at 1 atm? Note that the constant pressure heat capacities, , for water in vapor and liquid form are 36.4 and 75.3 respectively.
4Al + 3O2 = 2Al2O3 determine the percent yield if 124 g Al2O3 are produced when 3.0 moles of Al are reacted
Draw both resonance structures of the allylic cation formed when one molecule of adds to the symmetrical diene, 3,4-dimethylhexa-2,4-diene.
Some 2-methyl-2-butene may be produced in the reaction as a by-product. Give a mechanism for its production. (The experiment was to react t-pentyl alcohol with HCl.)
calculate the moles of CO2 you would theoretically expect from 0.203 grams of an alka-seltzer tablet at 700. torr and 285. K.
oxygen are required to react with 5.62 mol nitrogen to produce dinitrogen trioxide?
A household lightbulb is a blackbody radiator. Many light bulbs use tungsten filaments that are heated by electric current. What temperature is needed so that λmax=550nm?
Calculate the final temperature of 33 mL of ethanol initially at 13 degrees Celsius upon absorption of 657 J of heat. (density of ethanol =0.789 g/mL).
Amixture of nitrogen and water vapor is admitted to a flask whichcontains a solid drying agent. Immediately after admission, thepressure of the flask is 760 mm Hg.
Ions B and C react to form complex BC. If 20.0mL of 1.25M B is combined with 20.0mL of 1.25M C, 0.00650 mol of complex BC is formed. Determine the equilibrium constant for this reaction.
