Some students were investigating the speed of a toy car they built. They performed two trials and recorded their data in the table below: Trial 1 Trial 1 Tral 2 Trial 2 Distance (m) Time (sec) Distance (m) Time in (sec) 8.1 7.3 6 What was the average speed of the toy car during the two trials to the nearest tenth of a m/s? Be sure to use the correct place value. O A 25.4 m/s OB. 1.6 m/s O C. 3.0 m/s O D. 6.4 m/s​

Calculate the ratio of h+ ions to oh– ions at a ph = 7. 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 = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
