1. During a water balloon fight, Eric throws his balloon at Nick, who dodges like a ninja and the balloon hits a
brick wall and explodes. Nick tosses his balloon towards Eric, who cradles the balloon to a stop and the balloon
remains unbroken. Eric claims his secret is soft hands. Is he right? Justify your answer in terms of impulse.

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
