Determining the rate law for the reaction
The rate law for the reaction
NH4+ (aq) + NO2- (aq)------> N2 (g) + 2 H20 (l)
is given by the rate=k (NH4+) (NO2-)
At 25 C, the rate constant is 3.0 x 10^-4/M sec. Calculate the rate at this temperature if (NH4+)=0.26 M & (NO2-)=0.080 M

The ionization constant for the weak acid HA is 4.0 x 10^-8. Calculate the equilibrium concentration of H+, A- and HA in a 0.050 M solution of the acid.
Calculate the correct volume of sulfuric acid which will need to be added to neutrallize the base. The chemical reaction involves Al(OH)3 and Fe2O3 reacting with KOH and H2SO4 with the end product being KAL(SO4)2*12H2O.
How many L of solvent should be added to 0.46 L of a 0.28 M solution if you want a final concentration of 0.13 M.
Draw the structure of the unbranched isomer of C5H11Br that is most reactive in an SN2 reaction.
Select the correct IUPAC name for the following organic substrate, including the R or S designation where appropriate, and draw the major organic product(s) for the SN1 reaction.
If a solution contains 0.01M Ca^2+, 0.01 M Zn^2+, and 0.01 M Ni^2+ ions and you want to separate them using aqueous (NH4)2C2O2, which ion will precipitate first as an ozalate, CaC2O4, ZnC2O4, or NiC2O4
how would you make 100ml of a buffer with a pH =4.25, starting with 0.25 M acetic acid and 0.25M sodium acetate
Literally, the pH measurement is the electrochemical cell potential measurement. Can one use a normal multimeter to measure the cell potential and then convert it to solution pH? Why?
