Which of the following isomeric chlorides will undergo Sn2 substitution most readily? Why? a. 4-chloro-1-butene b. 1-chloro-1butene (cis or trans) c. 1-chloro-2-butene (cis or trans) d. 2-chloro-1-butene
Assuming ideality, how many grams of Xe are needed to inflate a bag with a volume of 867 mL at a pressure of 1.29 bar
A buffer was formed by mixing 50.0 mL of 0.206M NH4Cl(aq) with 45.0 mL of 0.222M NH3(aq) {Kb (NH3) = 1.8 x10-5 } . What is the pH of this buffer solution?
For the reaction above, how much would be liberated by the combustion of 5.00g of iron metal in excess oxygen.
Caffeine with a mass of .265 g was used to prepare caffeine salicylate derivative. How do you find the theoretical yield of caffeine salicyIate
every ten rounds an amplification of approximately 1000-fold. So, to get an amplification of 4.000 one would do 2 + 10 = 12 rounds . This, of course, assumes high yields for each step.
The falling down of a piece of chalk (when the hand holding it is taken off) is an energy-controlled process, because there is no change in its entropy in the process.
using the standard enthalpies of formation, what is the standard enthalpy of reaction? CO(g) +H2O(g) =CO2 (g) + H2 (g)
In solving weak acid equilibrium problems to find [H+] or pH, a major assumption is usually made. This major assumption can be represented by the following
how to find the molar concentration of a soloution of phosphoric acid if 17.8 mL of it neutralizes 20.0 mL of 0.050 mol/L calcium hydroxide.
Calculate the number of grams of sulfuric acid in 0.440 of battery acid if the solution has a density of 1.34 and is 39.1 sulfuric acid by mass.
A solution of 0.1% sodium dodycl sulfate (SDS) binds so strongly to polypetide chains that one detergent molecule is sufficient to saturate two amino acid residues.
if 50.00ml of Ba(OH)2 solution is mixed with 30ml of HBr solution, what is the pH of the resulting solution. (0.1385 M Ba(OH)2 and 0.2050 M HBr).
