HELP PLEASE ASAP :) What is the purpose of a salt bridge?
O.
A. To supply energy for the reaction
B. To connect two electrodes
O C. To prevent charge buildup
O D. To dissolve metals into solution

B. To connect two electrodes

Explanation:

The salt bridge forms a connecting link between the two electrodes. The function of the salt bridge is not to supply electrons from one electrolyte to another but to maintain a constant balance of charge as the electrons move from one half of the cell to the another. The electrons from from negative electrode to positive electrode that is from anode to cathode.

C. To prevent charge buildup

Explanation: I just took the quiz.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

indium, and thallium have three electrons i think
