Provide an explanation for the following scenario: Jim Bob was working in a laboratory. He needed to work up a reaction that used concentrated sulfuric acid. Jim Bob’s boss told him to use diethyl ether but he mistakenly used ethyl acetate. Jim mixed the ethyl acetate and the acid/aqueous layer and was waiting for the two to separate but they never did. What happened to the ethyl acetate under the strongly acidic conditions? Why would diethyl have been a better solvent?

Calculate: select the worksheet tab. this tab you calculate the analyte concentration. ï‚· fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.) ï‚· record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes. ï‚· record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
