How to draw an. electron dot diagram. 1 write the chemical aymbo of the atom.2. determine the number of valence electron the atom has.3. place first two dot on the right side of the symbol.4. place the remaining dots around the symbol( on the bottom. the left side, and on top) 5. there should not be any more than two dots on either side .top. or bottom, and no electron should be left over. its my first time doing these .

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).
