Answer:
Explanation:
The cations are positively charged ions and the anions are negatively charged ions.
Simple cations and anions are named:
Cations that are formed from metal atoms have the same name as metal. If a metal can form cations of different charges, the positive charge is indicated by a Roman number in parentheses after the name of the metal. Cations formed from non-metal atoms have names that end in -ium.
The names of monoatomic anions, as well as some polyatomic anions that do not contain oxygen, are formed by replacing the termination of the element's name with –ide.

What is the number of moles of electrons gained by 3.0 moles of lead ions?
(1) 5.0 mol (3)3.0 mol
(2) 2.0 mol (4) 6.0mol
Answers
Answer : The correct option is, (4) 6.0 mol
Explanation :
The given balanced ionic equation is,
In this reaction, lead undergoes reduction and chromium undergoes oxidation.
- Oxidation reaction : It is the reaction in which a substance looses its electrons. In this oxidation state increases.
- Reduction reaction : It is the reaction in which a substance gains electrons. In this oxidation state decreases.
Half reactions of oxidation and reduction are :
Oxidation :
Reduction :
From the reduction reaction, we conclude that 6 moles of electrons gained by the 3 moles of lead ions.
Hence, the correct option is, (4) 6.0 mole

Open ocean environment changes the most. The dominance of Earth's seas is clearly seen when viewed from space.
What is ocean?
A uninterrupted body with salt water that's also housed inside sizable basins on the surface of the Planet. The dominance of Earth's seas is clearly seen when viewed from space. At an average depth exceeding 3,688 meters, the oceans plus their peripheral seas cover about 71% of the area of the planet.
The remaining 29% of the planet's surface is made up of exposed land, which has a mean height of 840 meters (approximately 2,755 feet). Indeed, the oceans may cover the entire high terrain, reducing Earth to a smooth spherical. Open ocean environment changes the most.
Therefore, open ocean environment changes the most.
