Hydrazoic acid has a chemical formula of HN3. It is a volatile and toxic acid with a Ka value of 2.5 X 10^-5.
Although it might not be the best choice, a student prepares a buffer using HN3 and NaN3 solutions. Find the approximate pH of the solution s/he made by mixing 0.150L of 0.800M HN3 with 0.200L of 0.25 M N3^- (the sodium ion is omitted for clarity).
Calculate the change in temperature for 1.30 g of CaCl2 dissolved in 25.0mL of H2O. Assume that the calorimeter absorbs no heat. (ie C cal=0)
The pKa of aspirin (acetyl salicylic acid) is about 3 while the pH of stomach acid is about 1.0 Circle the approximate proportion of ionized (deprotonated and charged for acid) to unionized (protonated and uncharged for acid) aspirin that would oc..
What colume will 500 mL of gas at 20 degrees celsius and a pressure of 420 mm Hg occupy if the temperature is reduced to -80 degrees celsius
Would Br2 react faster with a tropylium cation or cyclooctatetrene? Not sure if the aromaticity of the cation comes into play here. Please justify your reasoning
