Answer:
This is the correct option:
HSO4– + H2O → SO42– + H3O+
Explanation:
The hydrogen sulfate or bisulfate ion HSO₄⁻ can act as either an acid or a base in water solution. This is called amphoteric
It can act as an acid, because it release a proton:
HSO₄⁻ + H₂O ⇄ H₃O⁺ + SO₄⁻²
It can act as a base, because it accepts a proton:
HSO₄⁻ + H₂O ⇄ H₂SO₄ + SOH⁻
Answer:
D. 4
Explanation:
Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.
Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface.
Hence, from the diagram provided above, the thin beam of light which illustrates reflection is the fourth because as it hit the surface, it bounced back to the medium from which it was originally propagated with.
