What exactly is chemical?

A chemical by definition is any substance consisting of matter; this includes solids, liquids, and gas. Chemicals can either be of a pure substance or a mixture of substances. A chemical substance such as water (H2O) is a pure chemical because it has the same molecules and combination throughout its structure.

What is a chemical short answer?

What is the most used chemical in the world?

Sulfuric acid is the world's most important industrial chemical! In North America we produce about 50 million tons a year, mostly by burning sulfur to form sulfur dioxide which is then reacted with water. Why do we need all that sulfuric acid?

Is soap a substance?

Like synthetic detergents, soaps are "surface active" substances (surfactants ) and as such make water better at cleaning surfaces. Water, although a good general solvent, is unfortunately also a substance with a very high surface tension.

What are the 4 types of chemical reactions?

The main four types of reactions are direct combination, analysis reaction, single displacement, and double displacement. If you're asked the five main types of reactions, it is these four and then either acid-base or redox (depending who you ask).

What are the 3 ways that chemical reactions are classified?

Chemical reactions are classified according to similar patterns of behavior. A large number of important reactions are included in three categories: precipitation, acid-base, and oxidation-reduction (redox).

What are the different types of reactions in chemistry?

The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories.

How do you identify a chemical reaction?

How can I tell if a chemical reaction is occurring? A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change.
