Chemistry – Matter and the Divisions of Matter

Matter is everything around you. It is the food you eat, the air you breathe and the clothes you wear. You too are made of something. Therefore, you need to know the different types, forms and characteristics of things.

A solid is anything that has weight and volume. Mass is the amount of inertia in matter and volume is the amount of space taken up by an object. Inertia is resistance to change and the greater the inertia the greater the weight.

SEPARATION OF ISSUES

Matter is often divided into two categories: pure substances and compounds. It’s important to be able to distinguish one type of thing from another so that you can explain the changes you see.

Clean stuff they include other materials with definite composition and definite properties. Pure substances are divided into two groups: elements and compounds.

Elements are the simplest types of chemical substances and cannot be broken down by normal chemical methods. Examples are hydrogen (H), sulfur (S) or gold (Au). The simplest form of an element is an atom.

Chemicals are chemical combinations of substances that can be described by a chemical formula and can only be separated by chemical methods. Examples of compounds are water, sugar and salt. The simplest form of a compound is the molecule or formula unit.

PROBLEMS

Mixtures are all around you. A salad is a mixture of vegetables, a glass of soda is a mixture of water, sugar and flavor and air is a mixture of gases such as nitrogen, oxygen and carbon dioxide.

Mixtures are physical combinations of two or more substances that have different contents, different properties and can be separated by normal physical processes. Conventionally, mixtures are divided into two main groups: those that are mixed and those that are not mixed.

Homogenous mixtures they are the same as a whole and do not differ in stages when left alone. Most homogeneous mixtures are solutions consisting of a solvent and a solvent. A solute is a solvent and a solvent is a solvent. The solutions are completely dissolved and see.

An alloy is a solution of two or more elements, at least one of which is metal, where the resulting elements have metallic properties. Alloys are often made to improve the properties of the materials they are made of. Steel, for example, is stronger than steel, its main component.

A diverse mixs has no definite structure and is fragmented when left alone. Heterogeneous mixtures can be separated by common physical methods. Examples of different mixes are blood, Italian salad dressing and soda pop.

Another type of mixture is a colloid. A colloid is a suspension that does not separate because the particles are not completely dissolved and remain suspended causing the mixture to appear cloudy. This darkness, called the Tyndall effect, is caused by the scattering of light by suspended particles.

A solution does not scatter light because the particles are at the molecular level and have a very small path to reflect light. However, colloidal particles are large enough to reflect light and small enough not to stay. The scattering of light from car headlights in fog and the light beam by dust particles are examples of the Tyndall effect.

Colloids they are formed in all combinations of solids, liquids or gases (except mixtures of non-reactive gases which are true solutions). Aerosols, foams, emulsions and sols are different types of colloids. Examples of colloids are shaving cream, cream and gelatin.
