Using the reaction below determine the limiting reagent, theoretical and % yield. 7.50ml of 1 pentene was allowed to react with 15 ml of HBr (9.0M). If 8.00 mL of 2 bromopentane is isolated what is the % Yield of the reaction
When drawing the lewis structure of TeCl4, WHY does Te have a lone pair. It's already connected to four Cl atoms and has 8 electrons.
What is the pH of a solution that is 0.20 M HC2H3O2 and 0.40 M NaC2H3O2? Ka for acetic acid 1.8 x 10-5. Explain
The pKa of acetic acid, HC2H3O2, is 4.76. A buffer solution was made using an unspecified amount of acetic acid and 0.30 mol of NaC2H3O2 in enough water to make 1.50 L of solution.
To convert this into a buffer having a pH of 9.3380, how many grams of KH2BO3 (M.W. 99.926) should be added to the solution?
