Please try to use one example around you to set up a experiment that can use laboratory equipment measuring the accurate value in the experiment to explain Charles's law Much obliged!

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)

Arecipe calls for 1.2 cups of oil. how many liters of oil is this?

The excretory system,need answers for all: )
