Describe the process in which elements of low mass, such as helium (2), and lithium (3), and elements of large mass, such as cobalt (27) and gold (79) are created. the answer should contain: supernova, low mass star, high mass star, nuclear fusion reaction

in a small paragraph please

Use examples from the article to explain one positive and one negative effect that chemistry has had on society.

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
