How many molecules of NH3 will be formed when 20.0L of N2 react at STP?
If you look at a reaction for an esterification reaction, you cannot tell where the oxygen comes from (acid or alcohol). Draw the mechanism of this reaction, and devise an experiment using the mechanism and O18 (O18 isotope) to help prove unequivo..
Give the structure for an isomer of compound A that has a melting point that is appreciably different from that of A yet NMR spectra that are almost identical to those of A. Include wedge/dash bonds.
Determine the dilution of the stock bleach solution (NaOCl). The bleach you will be using will be somewhere around 5.5% (weight/volume). Convert this to molarity.
A system absorbs 192 kj of heat and the surroundings do 110 kj of work on the system. what is the change in internal energy of the system.
the two reactions involved in quantitatively determining the amount of iodate in solution areio3-aq 5 i-aq 6 haq --gt
A 10.0 g piece of Al that is heated to 300.0 °C, is dropped into 250 mL of H2O at 25.0 °C (density of H2O = 1.00 g/mL). Compute the final temperature of the water. Specific heat of Al = 0.902 J/g°C as well as specific heat of H2O = 4.184 J/g°C.
A 0.2570g of pure sulfamic acid, HSO3 . NH2, is neutralized by a KOH solution. A 25.70 mL of KOH was added to the solution and 3.40 mL of HCl was used to back titrate the solution.

At a distance of 41 ft an ionizing radiation source delivers 4.5 rem of radiation. How close could you get to the source and still have no biological effects?
Food rots about 40 times more rapidly at 25° C than when it is stored at 4° C. Estimate the overall activation energy for the process of decomposition.
