BRAINLIST!! This activity highlighted several ideas about Plate Tectonics that you can work with during your investigation. Which of these ideas do you think will be the most helpful as you figure out where volcanic eruptions and earthquakes tend to happen? Your goal is to determine if volcanic eruptions and earthquakes happen more often near a specific type of plate boundary.

Modern weaponry has increased the number of deaths in wars and violent conflicts.

Astudent conducts an experiment to determine how the amount of water given to a plant affects its growth. what is the independent variable for this experiment?

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 .
