What is oxygen plus oxygen?

Answer 1

Except for He, Ne, A, Kr, Xe and Rn, the gaseous elements (such as hydrogen, oxygen, chlorine and nitrogen) usually combine two atoms into a molecule under standard conditions. Read your chemistry book to learn what conditions are considered the standard ones and why.

Two atoms of oxygen thus form one one molecule of oxygen, also called dioxygen. With a bit of persuasion (for instance by zapping a bolt of lightning through the air) three atoms of oxygen can join into ozone. Ozone is an allotropic form of oxygen.

Mixing oxygen gas with more oxygen gas under standard temperature and pressure does not create anything different. All you have is more oxygen.

Read your chemistry book to learn more about monatomic gases, allotropes and oxygen.

For more knowledge, investigate which elements are liquid at or near standard conditions, and whether they are monatomic. Similarly, investigate whether all the halogens are normally diatomic.

Answer 2

The reaction isȘ
FeO + H2SO4 = FeSO4 + H2O

Answer 3

Oxygen plus oxygen chemically combines to form dioxygen, which is commonly known as O2. This molecule is essential for respiration and is the most abundant form of oxygen in the Earth's atmosphere.

Answer 4

it is iron oxide.

Answer 5

Iron sulphide

Answer 6

Iron Sulfide
