From the unbalanced equation, Cu(s) + AgNO3(aq) → Cu(NO3)2(aq) + Ag(s), if 2.00 moles of copper and only 3.60 moles of silver nitrate are available to react,
which is the limiting reagent (reactant)? *

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

How are isotopes of the same chemical element alike? how are they different?
