How many molecules are there in 79g of Fe2O3? how many atoms is thi

Answers

Molar masses:
$m_(Fe) = 56g/mol\nm_(O) = 16g/mol\n\n\therefore m_{Fe_(2)O_(3)} = 2 \cdot (56)+3 \cdot (16) = 112+48 = 160g/mol$

So:

$1mol \ Fe_(2)O_(3) = 160g = 6 \cdot 10^(23)molecules$

160g ---------- 6·10²³molecules
79g ---------- x

x = 2.9625·10²³ molecules

1molecule = 5 atoms
2.9625·10²³ molecules = 2.9625·10²³·5 = 14.8125·10²³ atoms

When atoms react they form a chemical bond which is defined as?

Answers

A force of attraction that holds atom together
When atoms react they form a chemical bond which is defined as a force of attraction that holds atom together. A force of attraction is defined as a kind of force that draws two or more objects together regardless of distance. There are two major categories of forces of attraction, one is intramolecular and intermolecular. Intramolecular forces is the presence of forces in atoms internally. While intermolecular is the force by which the force that is existent in two or more elements.

Final answer:

A chemical bond forms when atoms react, creating an electrical attraction that results in a molecule. Molecules can be formed from the same or different elements. Chemical reactions involve the forming or breaking of these bonds.

Explanation:

When atoms react, they form a chemical bond. This bond is an electrical attraction, either weak or strong, that holds atoms in proximity to each other. The formation of this bond results in a stable grouping known as a molecule, which can be composed of the same or different elements. An example of this is H2, or molecular hydrogen. When the molecule is formed from different elements, it's called a chemical compound, such as H₂O (water) or CH4 (methane).

Chemical bonds form because it is energetically favorable for atoms to have a full outermost electron shell, creating stability. Atoms can obtain this stable configuration by donating, accepting, or sharing electrons with other atoms. Chemical reactions occur when these bonds are formed or broken, transforming the reactants (starting materials) into products (end results).

The correct answer is:

discovered the necleusproposed the proton existencediscovered fusion reaction from fission

Explanation:

Rutherford (1871–1937) was subject for an extraordinary array of discoveries in the fields of radioactivity and nuclear physics. He identified alpha and beta rays, set forth the rules of radioactive decay, and recognized alpha particles as helium nuclei.In 1911, Rutherford realized that atoms not detached, they are managed by something else, a nucleus. He noticed that the preponderance of an atom's mass is contemplated at a very tiny point in the center where the nucleus was determined. The nucleus is a positive force enclosed by electrons which are negative free flying particles.
