The water temperature rose from 22.50ºC to 23.17ºC. What is the specific heat of the lead pellet? (The specific heat of water is 4.184 J/gºC, and the density of water is 1.00 g/mL.)
How many grams of CaCl2 are needed to make 968.1 g of a solution that is 35.5% (m/m) calcium chloride in water? (Note that m/m has the same meaning as w/w.)
A compound A (C6H6) undergoes catalytic hydrogenation over Lindlar catalyst to give a compound B, which in turn undergoes ozonolysis followed by workup with aqueous H2O2 to yield succinic acid and two equivalents of formic acid.
