When alkyl halides react, rearrangements are likely to occur in which of the following types of reactions? A) SN1 B) SN2 C) E1 D) Both SN1 and E2 E) Both SN1 and E1
A 100.0 L weather balloon filled with 4.6 moles of helium has a small leak. If the helium leaks at a rate of 10 mmol/hr. what is the volume of the balloon after 57 hrs?
What is the Brownian diffusivity of a 0.2 um (micrometer) particle in air? Assume T = 293 K and P = 1 atm.
we had used a red dye, what changes would you make in your experimental procedure to determine the rate law for the oxidation of the red dye by sodium hypo-chloride?
Condensation polymers are made using a monomer with two functional groups which split off as the remainder of the two monomers are joined together. Often the small molecule eliminated in the process is water
an activation energy of 43.6 kJ/mol, what will be the rate constant for this reaction at 75oC?
A gaseous mixture of and contains 37.8 nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 785 ?
When 26.0 mL of 0.675 M H2SO4 is added to 26.0 mL of 1.35 M KOH in a coffee-cup calorimeter at 23.50°C, the temperature rises to 30.17°C. Calculate H of this reaction per mole of H2SO4 and KOH reacted.
what is steam distillation and why is it a preferred technique to purify high boiling liquids that are water-insoluble
What will be the value of E cell and E0 cell when the Cu/Zn battery has "run down" I.e., reached equillibrium? Also will the concentrations of Zn2+ and Cu2+ be large or small when the battery has "run down"? Does this make sense?
The electrons in the neutral carbon atom are redistributed so that there are three lone electrons in the three 2p orbitals and one lone electron in the 2s orbital.
When 0.100g of graphite is burned completely in a bomb calorimeter(heat capacity =3.344kJ/?C), containing 3000 g of water, a temperature rise of 0.21?C is observed.
Initial temperature of rod = 100 °C; mass of H2O in calorimeter =130 g; cH2O = 4.184 °C g . (Assume the calorimeter has negligible heat capacity).
