Write the reaction mechanism for the synthesis of 1-bromobutane from 1-butanol by reaction with sulfuric acid and sodium bromide. (sn2)
calculate the maximum volume in mL of .15 M HCl that each of the following antacid formations would be expected to neutralize. Assume complete neutralization.
For which of the following reactions does Hrxn representan enthalpy of formation. C(s) + O2(g) -> CO2(g) CO2(g) + C(s) -> 2 CO (g) CO2(g) + H2(g) -> H2O(g) + CO(g) 2 H2(g) + C(s) -> CH4(g)
The protein solution consists of albumin (40 g/L at Mm = 69,000 daltons), globulins (70 g/L at MW = 150,000 daltons), and fibrinogen (60 g/L at Mm = 340,000 daltons). Assume that T=25 C and the proteins form an ideal solution. What is the osmotic ..
A student measured the wavelength of hydrogen's visible red spectral line to be 647 nanometers. Which is a correct numerical setup for calculating the student's percent error.
The following questions pertain to the magnitude of the x-component of the speed(absolute value of the velocity) cx=|vx| of atoms in a gas, whose probability distriubution has the form P(cx)= ae^-bc2/x.
A 1.3717-g sample of impure oxalic acid dihydrate, H2C2O4·2H2O, required 34.49 mL of 0.1211 M NaOH for titration to the phenolphthalein end point (both protons neutralized). Calculate the percent oxalic acid dihydrate in the sample.
1for the reaction of c2h4g with o2g to form co2g and h2og what number of grams of co2 could be produced from 2.0 g of
Some alloys of early and late transition metals (e.g., ZrPt3) have much higher enthalpies of vaporization (per metal atom) than either of the pure metals
A weak acid (HA) has a pKa of 4.999. If a solution of this acid has a pH of 4.459, what percentage of the acid is not ionized
The four molecular p orbitals of the four carbon atoms can be lined up parallel in order to create four new molecular orbitals. The electrons in the new molecular orbitals benefit because they are not confined to just one atom.
If the rod has a diameter of 1000 inches and we want to cut a 1.00 kg section of the rod. How many cm long should it be?
How many g of product are actually used when a chemist calculates the theoretical yeild of a product at 20.1 g and the percentage of yeild is 87.1%
