Which statement BEST describes the force that makes Magnet 1 float above Magnet 2? A
The magnetic field from Magnet 1 attracts Magnet 2 which pushes Magnet 1
upward.
B
The magnetic field from Magnet 1 repels Magnet 2 which pushes Magnet 1
upward.
с
The magnetic fields from both Magnet 1 and Magnet 2 attract each other which
pushes Magnet 1 upward.
D
The magnetic fields from both Magnet 1 and Magnet 2 repel each other which
pushes Magnet 1 upward.

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 .
