Why do electrophiles have good leaving groups? how come nucleophiles dont have good leaving groups?
An aqueous solution is made by adding 50mL of 4.0 M NaCN to 30mL of 5.0 M HCN. Compute the pH of the solution.
Calculate the pH when 16 mL of 0.100 M sodium hydroxide is added to 10.00 mL of a 0.100 M phosphoric acid solution
Using an Erlenmeyer flask with 2ml of water instead of 50ml, would it make the experimental molarity higher, lower or no change compared to the actual valve?
Depict the initiation step one propagation step and the disproportionation termination step for the chain growth polymerization of vinylidene difluoride (1,1 -difluoroethene)
Calculate the activities and the activity coefficients for a chloroform-acetone solution in which Xa=0.6. the vapour pressure of pure chloroform at 50c is Pc* = 98.6 kpa and the vapor pressure for chloroform above the solution is Pc=53.3 kpa
The standard state of sulfur is solid rhombic sulfur. Use the appropriate standard heats of formation given in Appendix II in the textbook to find the average bond energy of the S=0 in SO2.
Question- A 17.75liters sealed vessel contains 1.512g of hydrogen, 4.000g of oxygen, 4.750g of florine and 33.52g of kypton at 28.0°c. 1) What is the pressure in the vessel
The following choices list some common laboratory solvents. In which of these solvents would LiCl be the LEAST soluble
Can someone please help me with the reaction mechanism of the oxidation of 9-fluorenol to 9-fluorenone using hypochlorous acid as an oxidizing agent.
how will the temperature of a gas sample change if its volume is decreased assuming everything else is the same and the
that the reaction was endothermic. If the enthalpy of reaction is negative, then we say that energy was released or that the reaction was exothermic. Most chemical reactions are exothermic.
The rate constant of a chemical reaction increased from 0.100 to 3.10 upon raising the temperature from 25.0 to 51.0. Calculate the value of 1/t2-1/t1
