In acidic solution, O3 and Mn2+ ions react spontaneously: O3(g) + Mn2+(aq) + H2O(l) → O2(g) + MnO2(s) + 2H+(aq) E o cell = 0.84 V Write the balanced half-reactions and calculate E o manganese when given E o ozone = 2.07 V. Include states of matter in your answers.

Which statement correctly describes potassium iodide, ki? there is a one-to-one ratio of potassium ions to iodide ions. potassium gains electrons and iodine loses electrons during the reaction. the lattice is held together by potassium anions and iodide cations.

May someone me with these science questions

16. why must the number of electrons lost equal the number of electrons gained in every redox reaction? use 3 – 4 sentences in your own words to address this question. 18. what type of radiation is emitted when chromium-51 decays into manganese-51? show the nuclear equation that leads you to this answer. 19. a radioactive nucleus alpha decays to yield a sodium-24 nucleus in 14.8 hours. what was the identity of the original nucleus? show the nuclear equation that leads you to this answer.
