(i) state three energy transfer mechanisms within a star for each mechanism, state whether it is significant in the core and in the outer regions of the sun. (ii) sketch the internal structure of a star with 0.08 mo < m < 0.5mo. state the source(s) of the energy. label the source(s) of energy and of energy transfer

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
