What evidence supports the law of conservation of energy? Light energy is converted to chemical energy during photosynthesis. Oxygen is made from the breakdown of carbon dioxide during photosynthesis. Energy is absorbed by chlorophyll during photosynthesis. The sun gives off light energy that is absorbed by plants.

when the pressure is increased, there will be a shift to the reactants side. decreasing the volume will increase pressure. when you decrease the volume, the gaseous species get more tightly packed of the concentrations of gaseous species increase.

le chatelier's principle says that the system wants to undo this concentration increase so it can decrease pressure.

since the reactants only have 1 mol of gas (only pcl5) and the products have 2 mol of gas (both pcl3 and cl2), it shifts to reactants to decrease concentration, thereby lowering the pressure

the correct answer is d. adding antifreeze to water in a car radiator in summer to raise the boiling point.
