Abrick is thrown upward from the top of a building at an angle of 25.7° above the horizontal and with an initial speed of 15.1 m/s. the acceleration of gravity is 9.8 m/s^2 if the brick is in flight for 3.4 s, how tall is the building? answer in units of m

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
