Assume this reaction takes place inside a thermally insulated container with immovable walls. If the chemical energy is increasing, explain where that energy comes from. If the chemical energy is decreasing, explain where that energy goes. Be specific and thoroughly explain your reasoning.

Compare the valence electron configuration of the nobles gas elements seen here. what statement is correct?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
