Question

question 2 (5 points) listen which process is used to produce gases from solutions of salts dissolved in water or another liquid? a) polar covalent bonding b) ionic bonding c) electrolysis d) metallic bonding

Explanation:

To solve this, we analyze each option:

• Option A: Polar covalent bonding is about electron sharing in molecules (e.g., H₂O), not gas production from salt solutions.
• Option B: Ionic bonding is the attraction between ions in a compound (e.g., NaCl), not a process to produce gas.
• Option C: Electrolysis involves passing electricity through an electrolyte (like salt solutions) to decompose it, producing gases (e.g., H₂ and O₂ from water electrolysis, or Cl₂, H₂ from NaCl solution).
• Option D: Metallic bonding is in metals (e.g., Cu, Fe), unrelated to salt solutions.

Thus, electrolysis is the process for gas production from salt solutions.

Answer:

C) Electrolysis
