Oxidation-reduction is often the most confusing and abstract part of chemistry for first-time chemistry students. Is it really w

orth the trouble? Think about the various chemical reactions that impact your life and society daily. Now, which ones are oxidation-reduction reactions versus some other type of reaction? Think about these reactions—redox or not—and take a reasoned position about the importance of redox reactions in our lives.

Yes its worth the trouble. We breathe in Oxygen and give out CO2. We burn wood. Our bikes rust.

How is density different from weight and mass?
defon

Hello there!

How is density different from weight and mass you say? It's simple!

1. Unlike weight, density is composed of mass and volume.

2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.

Hope this helps :) if so, can I get Brainliest?

Which of the following pairs of elements is most likely to form an ionic compound?1.Nitrogen and sulfur? OR 2. Magnesium and Flu
Fudgin [204]

Answer:

  • <u><em>Magnesium and fluorine.</em></u>

Explanation:

<em>Ionic compounds</em> are formed by the electrostatic attraction of cations and anions.

Cations, positive ions, are formed when atoms lose electrons, and anions, negative ions, are formed when atoms gain electrons.

When two different atoms have similar atraction for electrons (electronegativity) they will not donate to nor catch electrons from each other, so cations and anions will not be formed. Instead, the atoms would prefer to share electrons forming covalent bonds to complete their outermost shell (octet rule).

Then, in order to form ionic compounds the electronegativities have to substantially different. This situation does not happen between two nonmetal elements, which nitrogen and sulfur are. Then, you can predict safely that nitrogen and sulfur will not form an ionic compound.

Ionic compounds, then require the electronegativity difference that exist between some metals and nonmetals. Being magnesium an alkaline earth metal, its electronegativity is very low. On the other hand, fluorine the first element of the group 17, has the highest electronegativity of all the elements.Thus magnesium and fluorine will have enough electronegativity difference to justify the exchange of electrons, forming ions and, consequently, ionic compounds.
