Two freight trucks are traveling to the same destination, and each are traveling at a constant speed. Truck A is 187187 miles away from its destination at 9 a. m., one hour after leaving from its origin, and is 9999 miles away from the destination at 10:36 a. m. Truck B started traveling to its destination at 6:30 a. m. Truck B is 248248 miles away at 8:30 a. m. and 155155 miles away at 10 a. m. Analyze each situation to determine a function that finds the distance to the destination for each truck based on the time in hours after starting the trip from the origin to the destination

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 .
