In step 5, you will calculate h+/oh– ratios for more extreme ph solutions. find the concentration of h+ ions to oh– ions listed in table b of your student guide for a solution at a ph = 2. then divide the h+ concentration by the oh– concentration. record these concentrations and ratio in table c. what is the concentration of h+ ions at a ph = 2? mol/l what is the concentration of oh– ions at a ph = 2? mol/l what is the ratio of h+ ions to what is the concentration of h+ ions at a ph = 11?

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
