How<br> many<br> molecules are in 8.55x10-15 moles of a substance

solniwko [45]

Answer:

Know this

1mole of a substance contains 6.022x10²³molecules

Now

8.55x10^-15moles x 6.022x10²³molecules/1mole

=5.15x10^9molecules.

What does two bonded flurione atoms form?

Archy [21]

2 Fluorine atoms covalently bonded with each other, each sharing an equal number of a single, one valence electron to achieve a stable octet, would form a diatonic fluorine gas. It is a diatomic molecule, a molecule consisting of 2 atoms that are the same, in this case fluorine.

You identify a molecule in a pizza that is a polymer; has oxygen, hydrogen, and sulfur atoms; and is hydrophilic. What kind of m

matrenka [14]

The kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.

<h3>What is an amino acid?</h3>

An amino acid refers to a simple and organic chemical compound that consist of an acidic carboxyl group (COOH), a basic amino group ( $NH_2$ ), and a unique side chain group.

<h3>What is a protein?</h3>

A protein can be defined as a <u>hydrophilic</u>, macromolecule (polymer) that is formed as a result of the union of many amino acids.

Generally, a protein contains the following chemical elements:

Oxygen (O) atoms

Hydrogen (H) atoms

Sulfur (S) atoms

In conclusion, the kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.

hydrogen and oxygene react to form water l. How many molecules of O2 are required to produce 0.6 of H20

user100 [1]

Answer:

It is required 0.3 molecules of O2 to produce 0.6 molecules of H2O

Explanation:

The water´s formation reaction is: 2H2 + O2 --> 2H2O

This reaction shows the molecular O2:H2O ratio: 1:2.

Then, if we want to know how many molecules of O2 are required to produce 0.6 of H20, it is necessary calculate as it showed next:

0.6 molecules H2O * (1 molecula O2 / 2 molecules H2O)= 0.3 molecule O2
