Answer:

Word equation: <u>Potassium chlorate → Potassium chloride + Oxygen</u>

Chemical equation: <u>KClO₃ → KCl + O₂</u>

Explanation:

<em>This is decomposition reaction so there will only be one reactant, which is potassium chlorate.</em>

The chemical equation will be:

KClO₃ → KCl + O₂

The balanced equation would be:

2KClO₃ → 2KCl + 3O₂

The word equation will be:

Potassium chlorate → Potassium chloride + Oxygen

Delvig [45]

Answer:

A process during which chemical bonds between atoms are broken and new ones are formed, producing one or more substances.

Moles are the amount of substance that contains as many particles.

A chemical reaction is when a chemical change occurs for example when a nail comes into contact with air and is then exposed to air it begins to rust. It forms a red-brown substance which changes the chemical composition of the original compound.

Examples of chemical reactions:

Combustion

Oxidation (rusting)

Cooking an egg

Photosynthesis

Digestion

Fireworks

Paper Burnin

The mole is the amount of substance that contains as many particles (molecules, ions or atoms) as there are in 12g of carbon.

1 mol is the amount of substance that contains the same number of particles as there are atoms in 12.0 g of carbon-12 and that number is referred to as Avogardo's constant (6.022 x 10^{23}).
