A reversible reaction is one in which the reactants can be converted into products, and the products can be converted back into the reactants. This type of reaction occurs when the reactants and products are at equilibrium with each other. Examples of reversible reactions include the Haber process, the combustion of hydrocarbons, and the reaction …

In the laboratory, ammonia can be prepared by combining an aqueous solution of ammonium chloride and sodium hydroxide. The reaction is as follows: NH4Cl + NaOH → NaCl + H2O + NH3 The resulting ammonia solution can then be collected in a gas-tight container such as a bottle or flask. To prepare the solution, an …

Ammonia (NH3) is a colourless gas with a strong, pungent odour. It is a compound of nitrogen and hydrogen, and is commonly found in nature and industry. It is used in a variety of applications, including fertilizer production, cleaning products, and food and drug manufacturing.
Concentration of ores is the process of increasing the percentage of the desirable minerals in the ore by removing the unwanted materials. The process of concentration includes crushing, grinding, sieving, leaching, magnetic separation, froth flotation, and electrostatic separation.
Metal ores are minerals or rocks that contain a valuable metal or metal compounds. Examples of metal ores include copper, gold, and iron ore.
Copper plating on iron bangle is a process that involves electroplating a thin layer of copper onto the surface of an iron bangle. This is done by submerging the iron bangle in a copper sulphate bath that has been electrically charged. An electrical current is then passed through the copper sulphate solution, causing copper ions …

Electroplating is a process in which a thin layer of metal is deposited onto the surface of an object. This is usually done for decorative purposes, to improve corrosion resistance, or to improve the electrical conductivity of the object. The process involves passing an electric current through a solution containing ions of the desired metal, …
Electrolysis has many practical uses, including water purification, electroplating, electroforming, and the production of hydrogen and oxygen gas. It can also be used to separate dissolved ions from a solution, such as in the production of synthetic elements from their salts. Additionally, electrolysis can be used to clean surfaces, to coat objects with a thin …

The electrolysis of molten sodium chloride involves passing an electric current through the molten salt. As a result, chlorine is released at the anode and sodium is released at the cathode. The overall reaction is as follows: 2NaCl → 2Na + Cl2
Electrolytic cells are electrochemical cells that use electricity to drive a non-spontaneous reaction. This electricity is typically provided by an external source, such as a battery or power supply. Inside the cell, the electrical current causes ions to move between two electrodes, resulting in a chemical reaction that produces a product. This product can be …
