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.
What volume of O2(g) is required in the combustion at 25C and 1.00 atm if 9,818kJ are evolved?
If replacing magnesium with an equal weight of sodium, how would the enthalpy of the reaction changed?
The decomposition of ozone in the upper atmosphere is facilitated by {\rm NO}. The overall reaction and the rate law are O3(g) + O(g) = 2 O2(g) Rate = k [ O3}][ NO]
Calculate the change in pH when 7.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq).
A sample of neon has a volume of 610 mL when it is at a pressure of 867 mmHg. What will be the volume when the pressure is increased to 1760 mmHg
When an aqueous solution of an organic compound is shaken with an immiscible organic solvent, such as diethyl ether, the solute distributes itself between the two phases. When the two phases separate into two distinct layers, an equilibrium will h..
A gas-filled balloon having a volume of 2.50 L at 1.2 bar and 25°C is allowed to rise to the stratosphere (about 30 km above the surface of Earth), where the temperature and pressure are -23°C and 3.00 10-3 atm, respectively. Calculate the final v..
What is the new pressure, in atm,when the air is placed in tanks that have the following volumes, if there is no change in temperature and amount of gas?
Calculate concentrations of OH- and the pH of each basic solution. Since NaOH donates on OH- ion for each NaOH molecule, the OH- concentration is equivalent to the NaOH molarity. The pOH is calculated as -log[OH-] and the pH is calculated as 14-pO..
Nitrogen-13 is used in tracers injected into the bloodstream for positron emission tomography (PET). The half-life of nitrogen-13 is 10.0 minutes. How much time is required for the activity of a sample of nitrogen-13 to fall to 14.2 percent of its..
Calculate the change in pH when 46.00 mL of a 0.600 M solution of NaOH is added to 1.00 L of a solution that is 1.00 M in sodium acetate
In the chemical reaction used in automotive air-bag safety systems, N2(g) is produced by the decompositon of sodium azide, NaN3, at a somewhat elevated temperature:
