(a)What is the physical basis for the VSEPR model?
(b) When applying the VSEPR model, we count a double or triple bond as a single electron domain.Why is this justified?
The spatial relationship between the hydrogen on C-1 and the hydrogen on C-2 in the most stable chair conformation is: gauche, eclipsed with a 0 degree dihedral angle, eclipsed with a 120 degree dihedral angle, anti
silver nitrate, AgNO3; hydrochloric acid, HCL; and sodium carbonate, Na2CO3. You are to place the labels on the test tube using only the three solutions present. Here is your analysis procedure: A portion of test tube 1 added to a portion of test t..
A concentration of aqueous ammonia solution has a density of 0.90 g/ml and is 28.0% by mass ammonia. determine the molar concentration of this solution
In one experiment, the partial pressure increased from zero to 100 Pa in 522 s in a first-order reaction when the initial concentration of pyruvate ions in 100mL of solution was 3.23 mmol L^-1. What is the rate constant of the reaction
The linear form (y=mx+b) of the Arrhenius equation is given below : ln K = -Ea/RT + Ln A 1) In order to find the activation energy (Ea) you will need to make a linear graph
The second-order reaction 2 Mn(CO)5 Mn2(CO)10, has a rate constant equal to 3.0 x 10^9 M-1 s-1 at 25C. If the initial concentration of Mn(CO)5 is 2.0 x 10-5 M, how long will it take for 90.% of the reactant to disappear?
Why do we use an ethyl acetate/hexane mixture as a solvent in reaction of cyclopentadiene with maleic anhydride, rather than just pure hexane or ethyl acetate?
A student recrystillized 500 mg of an impure sample of naphthalene using methanol-water solvent pair and obtained 150 mg dried crystillized product
Compute the radioactive heat gain in watts by a loaf of bread at a surface temperature of 100 C. The surrounding oven surface temperature is1000 C. the total surface area of the bread is 0.15 m2 as well as the emissivity of the bread surface is 0...
An unknown is believed to be an alcohol because the IR spectrum showed broad absorption at 3200-3500 cm-1 and no absorption in the 1700-1750 cm-1 region.
