A 64 gram of metal temperature at 93°C to is placed in 60 grams water. The initial temperature of the water is 22°C. The final temperature of the
metal and water is 35ºC. Calculate the specific heat of the metal. The
specific heat of water is 4.18J/gºC.
Report your answer to 3 decimal places.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
