Iron is constantly working to support life on Earth, from supplying plants with nutrients to serving as a key component of steel to carrying oxygen in your blood.
- Iron is the most common metal, its pure form corrodes quickly when exposed to humid air and high temperatures.
- it is abundant in the sun and stars.
- It contributes to the synthesis of chlorophyll in plants.
- It is a part of hemoglobin, a blood protein that transports oxygen from the lungs to the body's tissues in mammals.
- The majority of it is used to create steel, an iron and carbon alloy used in manufacturing.
- There are four main structural forms of iron, known as allotropic forms, in which atoms are bound in various ways.
These are few properties of iron that are unusual for metal.

Mineral water is a type of mixture called a homogeneous solution. This is because there are very small amounts of dissolved minerals in mineral water, such as zinc, iron, copper, magnesium and many others. However, to the eye, mineral water just looks like distilled water.
To determine the heat change during a reaction, we need to know the heat of reaction of the process. For this case, the heat of formation is needed since it is a formation reaction. It will have units of kJ per mole. We determine the heat change as follows:
Heat change = 3352 kJ / 2 mol Al2O3( 1 mol Al2O3) = 1676 kJ
