Ido not enjoy chem at all someone plz me

Option A: Electrons flow from nickel fork to silver rod, which is a cathode.

In a cell, an electrode with lower standard reduction potential will undergo oxidation and act as an anode and the one with higher standard reduction potential will undergo reduction and act as a cathode. The movement of electrons always takes place from anode to cathode.

In the given cell, silver rod and nickel fork are taken as metal electrodes. The reduction half reaction of silver and nickel are as follows:

Here, the standard electrode reduction potential of silver and nickel is 0.80 V and -0.26 V. Since, the electrode potential of silver is more than that of nickel thus, silver rod will undergo reduction and it will be cathode.  Nickel fork will be anode as it undergoes oxidation.

Since, electrons flow from anode to cathode thus, it flows from Ni electrode to Ag electrode.

It satisfies the statement A, electrons flow from nickel fork to silver rod, which is a cathode. Therefore, correct option is A.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
