Which of these is a function of a salt bridge in an electrochemical cell?

It forces the electrons to travel through the inner circuit.
It connects the two half‑reactions.
It permits the charges to stay unbalanced in the two half‑cells.
It does not allow migration of ions between the solutions.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
