Causes and Effect

Corrosion very often we encounter in everyday life. Another name of corrosion is also called rust. Corrosion itself generally occurs in metal objects such as iron. Corrosion is the reaction between the metal with the surrounding substances such as air and water causing new compounds. In the composition of the new compound is a solid color brown reddish fragile and porous. The chemical formula of rust is Fe2O3.xH2O.

Causes of Corrosion

Corrosion can occur because of the reaction between metal and surrounding substances. In rust, this rust can occur due to moist air (oxygen and water) to corrode (react) to the iron so that a new substance appears reddish brown solids.

Effect of Corrosion

Corrosion-induced impacts can be direct and indirect losses. Direct losses include damage to equipment, machinery or building structures. While the indirect losses are the cessation of production activities, due to the replacement of equipment damaged by corrosion, even indirect losses can be the occurrence of accidents that cause casualties, such as the collapse of bridges due to corrosion, the occurrence of fire akiba gas pipeline leak due to corrosion, and explosion of the plant Nuclear power due to corrosion of the steam pipe.

Comparing one element with another, can also be applied to compare one thing with another, so that we can see clearly both Similarities and differences.

Clasification of matter

Material Classification

Matter is something that has mass and occupies a space. The material according to its form can be grouped into solids, liquids, and gases.

Chemists use symbols to distinguish one element from another. Elements in nature can be divided into metallic and nonmetallic elements. The next elements are arranged in the periodic form of the element.

Metal and nonmetal elements have different physical and chemical properties. Here are the differences in the properties of metallic and non-metallic elements.

Compound

Compounds are substances that can be broken down into two or more substances by chemical means. The compound is formed by chemically mixing, burning, or decomposing processes thermally or electrically. The nature of a compound will be different from its elements. Examples of H2O compounds

Mixed

The mixture is a material consisting of two or more substances and still has its original properties. The mixture is divided into 2, namely:

1. Heterogeneous

Heterogeneous mixtures are a mixture that can easily be distinguished. For example, a mixture of water and sand.

Homogeneous

2. Homogeneous

A homogeneous mixture is a material having two or more substances and is spread evenly, so it is not easy to distinguish the mixture. For example, a mixture of water and syrup.
