Explain why acid chlorides can be used to prepare amides but amides are not generally used to prepare acid chlorides?
Calculate the molarities of HC2H3O2 and NaC2H3O2 in the buffer solution you will prepare in this experiment. The buffer solution consists of 50mL and 0.20M of NaC2H3O2 and consists of 10mL and 1.0M of HC2H3O2
HbS has normal shape under normal conditions, but under conditions of low [O2] the hemoglobin forms fibrous aggregations, giving the entire red blood cell a sickle shape. (See image of eight HbS molecules at right.)
the solvent travel only half way up the chromatographic paper in the spot testing chromatogram.predict the effect of this procedural change on the solution of the cation in the standard mixture
What is the pH of the solution when the hydronium ion + concentration of 0.15 M CH3COOH is 6.3 × 10.
An experiment was performed to determine the Ksp of Ca(OH)_2_. A solution containing 2.00 x ^-2 M Ca(NO3)_2_ was saturated with Ca(OH)_2_ and filtered. Two samples of the saturated solution were titrated with 5.021x10^-2 M HCI, in order to determi..
Calculate the [Zn2+] in a solution of ZnC2O4 held at a pH of 3.00. Remember C2O4^2- is a weak base so you must consider other equilibria.
