When ch4(g) reacts with h2o(g) to form h2(g) and co(g), 206 kj of energy are absorbed for each mole of ch4(g) that reacts. write a balanced thermochemical equation for the reaction with an energy term in kj as part of the equation. note that the answer box for the energy term is case sensitive. use the smallest integer coefficients possible and put the energy term in the last box on the appropriate side of the equation. if a box is not needed, leave it blank. + + + +?

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
