N aqueous solutions, HF is a much weaker acid than HCl. However, when combined with Lewis acids, fluorinated systems make much stronger superacids than chlorinated ones. Which of the following best accounts for this phenomenon?
A. Aqueous, solvated F- ions are more stable in aqueous media than Cl- ions.
B. F- forms very stable complex anions through strong bonding to Lewis acids.
C. The basicity of the Cl- ion hinders its inclusion in complex anions.
D. The larger size of the Cl- anion sterically prevents its inclusion in the complex anion with a metal like Sb.

water pollution kills aquatic life. aquatic life includes algae and other plant life that use photosynthesis. photosynthesis takes   c02 out of the air.  

c02is a greenhouse gas.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
