A 100.0 mL sample of 0.10 M NH3 is titrated with 0.10 M HNO3. Determine the pH of the solution after the addition of 50.0 mL of HNO3. The Kb of NH3 is 1.8 × 10-5.
In the chlorination of cyclohexane there are two types of termination steps: recombination and disproportionation. 1) give two products of recombination:
What product will be obtained if you evaporated the water from NaOH extracts prior
Starting with 33 moles of O2 in a bottle, calculate the volume of O2 the bottle could deliver to a climber at an altitude where the temperature is -38 degrees Celsius and the atmospheric pressure is 0.37 atm
The ester ethyl p-nitrobenzoate is more reactive towards nucleophilic acyl substitution than ethyl p-methyoxybenzoate.
This might not be a good question to ask on here but I don't know where else to try and get some help. What I cant figure out is what buttons to push on my calculater

What is the heat change in J associated with 65 g of gaseous acetic acid at 127 oC changing to solid at -50 oC? c(acetic acid) (g) = 1.11 J/(g.K) c(acetic acid) (liq) = 2.18 J/(g.K) c(acetic acid) (s) = 1.32 J/ (g.K) ?Hfus(acetic acid) = 192 J/g ?..
Provide some diagnostically useful differences you would expect in the IR spectra between starting materials and product for the reaction you carried out (e.g. if I was asked this regarding the oxidation of cyclohexanol to cyclohexanone
Draw the structure of the 4 possible ionization states of tyrosine and calculate the net charge for each state. Draw the titration curve for Tyrosine. The pKa of the carboxylic acid = 2.20. the pKa of the amino group is 9.20.
Draw isotherms generated by this equation which are at the critical temperature, above the critical temperature, and below the critical temperature. Also, mark on the sketch the critical volume and the critical pressure for the gas.
If the standard deviation of your pipet is 0.018 mL, what is the chloride concentration ppt (W/V) of you sample?
Gastric juice is made up of substances secreted from parietal cells, chief cells, and mucous-secreting cells. The cells secrete HCl, proteolytic enzyme zymogens, mucin, and intrinsic factor
