think about the process of raising a pendulum to one side and letting it go. for this event, create a list associated with the pendulum as it cycles from the choices below:

kinetic energy forms:
- motion energy
- thermal energy
- electric energy
- vibrational energy
- radiant energy

potential energy forms:
- gravitational potential energy
- elastic potential energy
- chemical potential energy
- electric potential energy
- magnetic potential energy
- nuclear potential energy

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 .
