Calculate E°_cell for the Cell for the Reaction 2 Ga(s)

question 43

Multiple Choice

Calculate E°_cell for the cell for the reaction 2 Ga(s) + 3 Sn⁴⁺(aq) → 3 Sn²⁺(aq) +2 Ga³⁺(aq) . The standard reduction potentials are as follows:
Ga³⁺(aq) + 3 e− → Ga(s)
E° = -0.55 V
Sn⁴⁺(aq) + 2 e− → Sn²⁺(aq)
E° = 0.15V
​

• A) 0.70 V
• B) 0.40 V
• C) 0.33 V
• D) -0.40 V
• E) −0.70 V

Ribosomes

Cellular structures responsible for synthesizing proteins from amino acids during the process of translation.

Protein Synthesis

The process in which cells make proteins, involving transcription of DNA to mRNA and translation of mRNA to a polypeptide chain.

Peroxisomes

Organelles found in virtually all eukaryotic cells, involved in the catabolism of very long chain fatty acids, branched chain fatty acids, bile acids, and xenobiotics.

Liver Cells

Hepatocytes, the main functional cells of the liver, involved in protein synthesis, detoxification, and metabolism.
