The map below shows the locations of four active volcanoes in the What do these volcanoes indicate about plate tectonics in the region?
F The volcanoes form an island arc, indicating a converging plate boundary.
G The volcanoes form a line, indicating a diverging plate boundary.
HTwo plates are moving past each other, causing faulting and magma formation.
JTwo plates are moving apart, creating new seafloor

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 .
