Natalie observes these characteristics in the model of an atom. (i) includes positive charge (ii) contains electrons (iii) explains the photoelectric effect (iv) suggests the probable location of electrons which model is natalie most likely examining? bohr model dalton’s model plum pudding model electron-cloud model

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).
