Definition: A type of mineral that is a source of potassium nitrate, often used in fertilizers and food preservation.

Example: The farmer used nitre to improve the soil quality for his crops.

Definition: A chemical compound that includes nitrogen and another element that is more positive in charge, like a metal or phosphorus.

Example: Silicon nitride is often used in high-performance ceramics.

Definition: To treat a material, especially steel, so that nitrogen is absorbed into its surface to make it harder.

Example: The engineers decided to nitride the steel components to improve their durability.

Definition: A process used to harden the surface of steel by allowing nitrogen to be absorbed into it, usually by heating it with ammonia.

Example: Nitriding is commonly used in the manufacturing of durable tools and components.

Definition: A type of bacteria that helps convert ammonia into nitrates in the soil, playing a key role in the nitrogen cycle.

Example: Nitrifiers are essential for healthy soil as they help plants access nutrients.

Definition: To convert ammonia or its compounds into nitrates or nitrites, often through a biological process involving bacteria.

Example: Farmers often nitrify the soil to enhance its nutrient content for better crop growth.

Definition: A type of organic compound that includes a specific group of atoms known as the cyano radical, which is represented by the formula -CN.

Example: Nitrils are often used in the production of various chemicals and pharmaceuticals.

Definition: A type of organic compound that contains a carbon-nitrogen triple bond, often used in the production of synthetic rubber and plastics.

Example: Nitrile gloves are commonly used in medical settings because they are resistant to chemicals and punctures.

Definition: Relating to or containing a nitro group, which is a chemical group that can make compounds unstable and sometimes explosive.

Example: The chemist worked with nitro compounds in the laboratory, taking special precautions due to their instability.

Definition: A substance related to nitroglycerin or a chemical group containing nitrogen and oxygen, often used in explosives or medications.

Example: The doctor prescribed nitro to help with the patient's heart condition.

Definition: A harmful chemical substance that can be a yellow liquid or crystals, often used in making other chemicals and products.

Example: Nitrobenzene is used in the production of dyes and pharmaceuticals.

Definition: A type of material made from cellulose that has been chemically treated with acids, commonly used to create explosives, plastics, and other products.

Example: Nitrocellulose is often used in the production of smokeless gunpowder.
