How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?

On a power source such as a battery, the anode is labelled with a + (plus)

The cathode on the other side is labelled with a - (minus)

When ionic compounds ionize, they produce both positive and negative ions.

Anion- This is a negatively charged ion for example chloride ion (Cl⁻)

Cation- This is a positively charged ion for example sodium ion (Na⁺)

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
