How do you explain combustion?

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer. The fuel can be a solid, liquid, or gas, although for airplane propulsion the fuel is usually a liquid.

What is a complete combustion?

Complete combustion happens when there is a good supply of air. Carbon and hydrogen atoms in the hydrocarbon fuel react with oxygen in an exothermic reaction: carbon dioxide and water are produced.

How do you know if a complete combustion has occurred?

Combustion requires three things to occur: fuel (hydrocarbons), oxygen (from the air), and a catalytic spark. Complete combustion will produce only carbon dioxide and water as the products and nothing will be leftover. Incomplete combustion will produce other byproducts like carbon monoxide or carbon soot left behind.

Which type of reaction is involved in white was of walls?

Chemical Reactions and Equations. When we white-wash the walls, then first calcium oxide (oxide) is made to react with water to form calcium hydroxide. The calcium hydroxide is then applied to the walls, which slowly reacts with the carbon dioxide gas present in air to form a thin shining layer on the walls.

What is the formula of whitewashing?

(1) The solution of the substance used for whitewashing is calcium oxide also called quicklime with chemical formula CaO.

What does Blackwashing mean?

blackwashing (uncountable) (derogatory) The revisionist portrayal of something as belonging to a black race of people. The application of a coating of blackwash. (derogatory) The revisionist portrayal of something as evil.
