After a reaction between steam and hot carbon.
water gas is prepared by steam over white hot coke
The usual laboratory method for making acetylene is by adding (dropwise) water to calcium carbide:CaC2 + 2 H2O → C2H2 + Ca(OH)2Calcium carbide is very cheap and available without restrictions in most countries.
Freshly prepared lime water is used in experiments to test the evolution of gases because it turns milky when carbon dioxide is present. This is a simple and visual way to detect the presence of carbon dioxide gas, which is often a byproduct of various chemical reactions, including those related to the process of evolution.
Hydrogen gas is prepared using Vanaspati or Dalda through a chemical reaction called the hydrogenation of oils. This process involves heating the Vanaspati or Dalda with a metal catalyst to produce hydrogen gas as a byproduct.

Oxygen can be prepared by the electrolysis of water. 2H2O + electricity --> 2H2 + O2
Water gas is a mixture of carbon monoxide and hydrogen produced by the reaction of steam with hot carbon, such as coke. It is prepared by passing steam over red-hot coke at high temperatures in a process known as steam reforming. The resulting gas can be used as a fuel or as a feedstock in the production of chemicals like ammonia.
Chlorine gas is commercially prepared by the electrolysis of brine (sodium chloride solution) in a process known as the chlor-alkali process. This method involves passing an electric current through brine to produce chlorine gas, sodium hydroxide, and hydrogen gas. The chlorine gas is then collected and used in various industrial applications, such as water treatment and chemical manufacturing.
we prepared environment......... it is prepared by wind,water,fire,sand...
Ammonia gas in the world is mostly prepared by Haber's process N2 + 3H2 = 2NH3 when this gas is dissolved in water ammonium hydroxide is formed.
Gas is not prepared from sand.
Fuels that are processed and prepared from raw or primary fuels are called secondary type of fuels. Examples are charcoal, coke, petrol, diesel, kerosene, gobar gas, water gas.
Wear gas masks, stay inside, and be prepared to evacuate if neccicary.
