Answer:

A chemical reaction involves, breaking and making of bonds between reactants to give rise to formation of new products. A chemical reaction is basically rearrangement of atoms.

By definition, chemical reactions are those that cause the chemical bonds between atoms to break and reorganize, giving rise to different substances.

<h3>Substances present in a chemical reaction</h3>

In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.

<h3>Mass of a chemical reaction</h3>

The mass of the participating substances is the same before and after the reaction, that is, it is conserved. This happens because only a rearrangement takes place between the atoms of the reactants, which break and form new bonds.

<h3>Energy necessary of a chemical reaction</h3>

It must be taken into account that for a chemical reaction to occur the reactants must collide since energy is necessary to break the chemical bonds between atoms.

<h3>Summary</h3>

In summary, chemical reaction is the way one substance reacts against another. In this way, the chemical bonds between atoms are broken and new bonds are formed.

Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

<u>Stoichiometry</u>

Using Dimensional Analysis

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[Given] 0.54 moles Cu

[Solve] atoms Cu

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

[DA] Set up: $\displaystyle 0.54 \ mol \ Cu(\frac{6.022 \cdot 10^{23} \ atoms \ Cu}{1 \ mol \ Cu})$
[DA] Multiply [Cancel out units]: $\displaystyle 3.25188 \cdot 10^{23} \ atoms \ Cu$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 2 sig figs.</em>

3.25188 × 10²³ atoms Cu ≈ 3.3 × 10²³ atoms Cu
