Scientists use scientific notation to simplify numbers, basically. When dealing with really big numbers or really small numbers, the usage of scientific notation prevents them from having to write a bunch of zeroes.
Hope that helped you!
Answer:
The standard potential, E cell, for this galvanic cell is 0.5670V
Explanation:
Ni²⁺(aq) + 2e⁻ → Ni(s) E red = - 0.23V ANODE
Cu²⁺(aq) + 2e- → Cu(s) E red = + 0.337V CATHODE
ΔE° = E cathode - E anode
ΔE° = 0.337V - (0.23V) = 0.5670 V
When lithium reacts to chlorine it goes from having no charge to +1 charge, while chlorine goes from neutral to having -1 charge.
<span>1 mol mag acetate dissociates into 1 mol Mg ion and 2 mols acetate ions in water. Therefore, if 0.6 mol mg of acetate is dissolved in 0.135 literss of water, we will have 0.6/0.135 = 4.44 moles / lit Mg2+ ions and 0.6*2/0.135 = 8.88 moles / liter C2H3O2- ions.</span>
