What is missing from the solubility graph shown on the right? A graph with temperature in degrees Celsius ranging from 0 to 100 in units of 20 on the horizontal axis and unidentified tick marks from 0 to 300 in increments of 50 on the vertical axis. An orange line curves upward from 0, 90 through 50, 125 to 100, 245.

answer: mole of the gas

answer: mole of the gasexplanation:

answer: mole of the gasexplanation: this is because 1 mole of a gas is 22.4dm³, which is use in ideal gas

B? i feel like this is a trick  

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
