I think it's A, <span>an action which causes movement and an opposite reaction</span>
In the reaction Sn(s) + 2H+(aq) → Sn2+ (aq) + H2(g)
from this reaction, we get that Sn loses from 0 to 2 electrons so it's oxidized So it is the reducing agent.
and H gains from 0 to 1 electrons so, it's reduced so ∴ it is the oxidizing agent
The types of intermolecular forces that occur in a substance will affect its physical properties, such as its phase, melting point and boiling point.
Answer:
D: Atmospheric pressure is greater than vapor pressure,and water molecules escape from the solution into the air.
