Given that g for the reaction below is –957.9 kj, what is gf of h2o? 4nh3(g) + 5o2(g) =4no(g) + 6h2o(g)

gf,

nh3 = -16.66 kj/mol

gf, no = 86.71 kj/mol –228.6 kj/mol –206.4 kj/mol 46.7 kj/mol 90.7 kj/mol

What is the chemical formula of the following compound

Calculate the molarity of 48.0 ml of 6.00 m h2so4 diluted to 0.250 l .

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
