Sort the following into the classification for a reaction that is NOT at equilibrium versus a reaction system that has reached equilibrium. Drag the appropriate items to their respective bins. View Available Hint(s) The forward and reverse reactions proceed at the same rate. Chemical equilibrium is a dynamic state. The ratio of products to reactants is not stable. Reset Help The state of chemical equilibrium will remain the same unless reactants or products escape or are introduced into the system. This will disturb the equilibrium. The concentration of products is increasing, and the concentration of reactants is decreasing. The ratio of products to reactants does not change. The rate at which products form from reactants is equal to the rate at which reactants form from products. The concentrations of reactants and products are stable and cease to change. The reaction has reached equilibrium. The rate of the forward reaction is greater than the rate of the reverse reaction. The…

Place the following characteristics into the box for the correct ion. Note that some of the characteristics will not be placed in either bin. Use your periodic table for assistance. Link to Periodic Table Drag the characteristics to their respective bins. ▸ View Available Hint(s) This anion could form a neutral compound by forming an ionic bond with one Ca²+. Reset Help This ion forms ionic bonds with nonmetals. This ion has a 1- charge. This is a polyatomic ion. The neutral atom from which this ion is formed is a metal. The atom from which this ion is formed gains an electron to become an ion. The atom from which this ion is formed loses an electron to become an ion. This ion has a total of 18 electrons. This ion has a total of 36 electrons. This ion has covalent bonds and a net 2- charge. This ion has a 1+ charge. Potassium ion Bromide ion Sulfate ion
