What conclusion can be draw about the heat of fusion of water from the heating curve? A) The potential energy of fusion represen
ts a greater change of stored energy. B) Liquid water is stabilized by strong intermolecular forces between the molecules. C) The kinetic energy and the entropy of the water molecules increases through fusion. D) The temperature increase converts potential energy to kinetic energy during fusion.
The reaction: 2H2(g) + O2(g) → 2H2O(g), can be interpreted as: a. 2 moles of hydrogen gas reacts with 1 mole of oxygen gas to produce 2 moles of water.
Because speed is a scalar quantity which he has only magnitude and no direction while velocity is a vector quantity because it has both magnitude and direction.
