You are given a vector in the xy plane that has a magnitude of 90.0 units and, a y component of -41.0 units. assuming the x component is known to be positive, specify the vector, v, if you add it to the original one, would give a resultant vector that is 89.0 units long and points entirely in the -x direction.

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
