Your lab partner is typically spot-on, but today they are having an awful day. Instead of using concentrated sulfuric acid in this exercise, they used concentrated hydrochloric acid. Provide the product when HCl is used rather than H2SO4. What type of reaction mechanism will this reaction undergo with the 3,4-dimetyl-3-hexanol substrate (SN1, SN2, E1, or E2)? and show the products of the reaction
A graduated cylinder contains 110. mL of water. A 10.0 g piece of iron (density = 7.86 g/cm3) and a 18.9 g piece of lead (density = 11.3 g/cm3) are added. What is the new water level in the cylinder?
