0.500 g of CuI was used to couple 2.0 mL of 1-hexyne what is the mole % of the CuI catalyst that was used? This is as Cu-catalyzed diazo coupling reaction that coupled ethyl diazoacetate with 1-hexyne.
If the measured gas pressure in a collection flask during a gas-forming reaction was determined to be 1.44 atm, and the atmospheric pressure that day was measured as 0.95 atm.
Estimate the mass of water that must evaporate from the skin to cool the body by 0.50^circ C. Assume a body mass of 85 kg and assume that the specific heat capacity of the body is 4.0 {rm{J}}/{rm{g}}; cdot ;^circ {rm{C}}.
Twenty grams of liquid mercury at 98.0 °C is placed in 47.0 g of water initially at 25.0 °C. What is the final temperature of the water, assuming the styrofoam calorimeter absorbs no heat at all?
