30 points studying the decay of radioactive isotopes in dead organisms scientists to identify fossilized remains. the ratio of c-12 to c-14 in the atmosphere is 1 x 1012. the table shows this ratio inside the body of three organisms. c12/c14 ratio organism c12/c14 ratio x 8 x 1012 y 2 x 1012 z 1 x 1012 what can most likely be concluded from the above information? only organism z is alive, and organism x has been dead longer than organism y. only organism z is alive, and organism y has been dead longer than organism x. only organism x is alive, and organism y has been dead longer than organism z. only organism x is alive, and organism z has been dead longer than organism y. read the chemical equation shown. 3so2 + 2hno3 + 2h2o → 3h2so4 + 2no which statement is true about this chemical equation? h (hydrogen) was oxidized and s (sulfur) was reduced. h (hydrogen) was reduced and n (nitrogen) was oxidized. s (sulfur) was oxidized and n (nitrogen) was reduced. s (sulfur) was reduced and n (nitrogen) was oxidized. read the following chemical equations. reaction 1: h2s + cl2 → 2hcl + s reaction 2: fe + s → fes which of the following statements is true for both the chemical equations? chlorine is reduced in reaction 1 and iron is reduced in reaction 2. chlorine is oxidized in reaction 1 and iron is oxidized in reaction 2. chlorine is oxidized in reaction 1 and iron is reduced in reaction 2. chlorine is reduced in reaction 1 and iron is oxidized in reaction 2.
