The second ionization energy of lithium is much greater than the first ionization energy
Hitman42 [59]

Mg: [Ne] 3s2. The second ionization energy of Mg is larger than the first because it always takes more energy to remove an electron from a positively charged ion than from a neutral atom. The third ionization energy of magnesium is enormous, however, because the Mg2+ ion has a filled-shell electron configuration.

Which describes the role of oxygen in photosynthesis?
Basile [38]
Photosynthesis is the process utilized in the chloroplasts of plant cells, where carbon dioxide and water undergo a chemical process with radiant energy, usually from the sun. The resulting products are energy stored in the form of a glucose molecule, and oxygen, which is given off as a waste product.

Match each state of matter with the statement that best describes it.
Stells [14]

Answer:

State of matter is defined as a form in which matter can exist. There are four states of matter known till date. They are as follows:

Solid: Matter is said to be in solid state if it has definite shape and volume. The components of matter are closely packed and have fixed positions within the matter.

Liquid: In liquid state, matter has fixed volume but shape is not fixed, it takes the shape of container in which it is placed. The particles of liquid are close but can move freely or do not have fixed positions.

Gas: Matter in gaseous state has variable volume and shape. The particles of gas are very far from each other thus, they are in constant motion without any fixed position..

Plasma: This state of matter has variable shape and volume. It has neutral atoms, the number of ions and electrons are significant and can move freely in the matter. In order to make plasma, energy is required to strip electron from atom.

According to above definitions, the state of matter is matched with the given statements as follows:

Plasma-Particles are so hot that electrons are stripped from atoms.

Gas-It expands to fill the volume of the container.

Liquid-Particles move past each other freely but do not go fat apart.

Solid-It retains its shape regardless of the shape of the container.

Explanation:

I choose this because It understands how each plasma work.
