Nick wanted to see how high an ice cube would float in different temperatures of water. Identify the independent variable. A. size of ice cube
B. amount of water
C. temperature the ice cube was at its' highest height
D. height of ice cube
E. temperature of water

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 -

Pretty sure it's d. heterogeneous is separated by physical properties.
