Assuming an ideal situation, calculate the vapour pressure of a solution composed of equal mole fraction of benzene C6H6 and toluene C7H8 at 250C. Given the vapor
pressure of pure benzene and pure toluene is 95.1

and 28.4 mm Hg respectively.​

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

indium, and thallium have three electrons i think

i think its 100.

hope this !
