When you drop a 0.45 kg apple, Earth ex- erts a force on it that accelerates it at 9.8 m/s?
toward the earth's surface. According to New
ton's third law, the apple must exert an equal
but opposite force on Earth
If the mass of the earth 3.98 x 1024 kg, what
is the magnitude of the earth's acceleration
toward the apple?
Answer in units of m/s

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
