For a particle described by l = a) show that if u = e = t + u is constant - = u(i,#), b) show that if u then e is conserved, but it is not necessarily e t+u. ta +t-u(a- ), show that p = pa +p, is conserved. hint: try defining 12. for l new coordinates: x = fg+ i»

Calculate the ratio of h+ ions to oh– ions at a ph = 6. 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 = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
