Describe the PURPOSE of Moh's hardness scale. (What information does it tell you)

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

Calculate the mass of silver needed to react with chlorine to produce 126g if silver chloride?

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
