A cobalt(II) salt was dissolved in water and reacted with excess acetylacetone (2,4-pentanedione, CH3COCH2COCH3) and hydrogen peroxide. A green solid was formed that gave the following results for elemental analysis: C: 50.4%, H:6.2%, Co:16.5% (all by mass). Determine the ratio of cobalt to acetylacetonate ion in the product. What was the purpose of the hydrogen peroxide in the reaction

Compare and contrast physical changes with chemical changes.

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?
