Me now asap now, find the concentration of h+ ions to oh– ions listed in table b of your student guide for a solution at a ph = 11. then divide the h+ concentration by the oh– concentration. record these concentrations and ratio in table c. what is the concentration of h+ ions at a ph = 11? mol/l  what is the concentration of oh– ions at a ph = 11? mol/l   what is the ratio of h+ ions to oh– ions at a ph = 11? : 1, or 1:

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
