Answer:
See explanation below
Explanation:
In an electrochemical cell, electricity is obtained by the gradual deterioration of the anode.
Hence, surface area of the metal will affect the length of time within which the electrochemical cell works.
The greater the surface area of the metal, the longer the electrochemical cell can function and the greater the quantity of electricity produced, hence the answer above.
Improper or incomplete usage of citations can lead to plagiarism.
Without proper usage of citations, teachers or whoever is looking over your work, may think because you do not hold acceptable citations, that they will think it is plagiarized. Plagiarism is taking another person's work or ideas without citing it. Citation or direct quotation could save you from plagiarism.
Answer:
Atoms only share electrons in covalent bonds. covalent bonds are only formed between nonmetals. there are two different types of covalent bonds; polar and nonpolar. in a polar covalent bonds electrons are shared unequally because one atom has a stronger force of attraction than the other (EX. H2O). In a nonpolar covalent bond, the electrons are shared equally because they're electronegativity is also equal (EX. Cl2).
Overall, the atoms electronegativity determines the way it shares electrons
From left to right the electronegativity increases
Answer:
See below
Explanation:
The half-cell reduction potentials are
Ag⁺(aq) + e⁻ ⇌ Ag(s) E° = 0.7996 V
Co²⁺(aq) + 2e⁻ ⇌ Co(s) E° = -0.18 V
To create a spontaneous voltaic cell, we reverse the half-reaction with the more negative half-cell potential.
We get the cell reaction
:
Anode: Co(s) ⇌ Co²⁺(aq) + 2e⁻
<u>Cathode: 2Ag⁺(aq) + 2e⁻ ⇌ 2Ag(s) </u>
Overall: Co(s) + 2Ag⁺ (aq) ⇌ Co²⁺(aq) + 2Ag(s)
