How many electrons must be removed from each of two 5.400 kg copper spheres to make the electric force of repulsion between them equal in magnitude to the gravitational attraction between them? Give your answer in scientific notation.

The correct answer is c

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

The correct answer is "atomic weight".

Answer is: hydrogen is being oxidized.chemical reaction: co₂ + h₂ → co + h₂o.oxidation half reaction: h₂ → 2h⁺ + 2e⁻.reduction half reaction: c⁺⁴ + 2e⁻ → c⁺².oxidation is increase of oxidation number, hydrogen change oxidation number from neutral charge (in molecule of hydrogen) to oxidation number +1 (in water).
