Explanation:

both reduction and oxidation are occurring simultaneously, this is known as a redox reaction. An oxidizing agent is substance which oxidizes something else. In the above example, the iron(III) oxide is the oxidizing agent. A reducing agent reduces something else

<h2>ANSWER:</h2>

The oxygen atoms undergo reduction, formally gaining electrons, while the carbon atoms undergo oxidation, losing electrons. Thus oxygen is the oxidizing agent and carbon is the reducing agent in this reaction.

Write the condensed ground-state electron configurations of these transition metal ions, and state which are paramagnetic:

jok3333 [9.3K]

Answer:

a) Mo the electron configuration: 42Mo: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d4

Mo3+ - is Paramagnetic

b) Au - [Xe] 4f14 5d10 6s1

For Au+ is not paramagnetic

c) Mn - [Ar] 3d5 4s2

Mn2+ is paramagnetic

d)Hf -[Xe] 4f¹⁴ 5d² 6s²

Hf2+ is not paramagnetic

Explanation:

An atom becomes positively charged when it looses an electron.

Diamagnetism in atom occurs whenever two electrons in an orbital paired equalises with a total spin of 0.

Paramagnetism in atom occurs whenever at least one orbital of an atom has a net spin of electron. That is a paramagnetic electron is just an unpaired electron in the atom.

Here is a twist even if an atom have ten diamagnetic electrons, the presence of at least one paramagnetic electron, makes it to be considered as a paramagnetic atom.

Simply put paramagnetic elements are one that have unpaired electrons, whereas diamagnetic elements do have paired electron.

1. What is the function of the circulatory system? * 10 points A. Provide blood with oxygen from the air, & to get rid of ca

kifflom [539]

Answer:

B. Carry oxygen, nutrients, waste, & to fight pathogens

Explanation:

The circulatory system refers to all organs and tissues involved in carrying blood and lymph around the body.

The circulatory system carries oxygenated blood from the heart to cells and deoxygenated blood back to the heart.

Nutrients are carried in the blood to cells in different parts of the body and waste products are also carried from cells in the blood.

White blood cells is a component of blood in the circulatory system that fights off diseases.

What is chemistry and what types of questions do chemists try to answer

Reil [10]

Answer:

Chemistry is the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.

They answer questions like, like "What makes up this material?," "How does this material change when heated or cooled,?" What happens when I mix this material with another material,?" and "What rules determine how materials change in different situations?" What makes up Chemical X?
