Carbon dioxide (chemical formula CO 2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.
Natural gas liquids (NGLs) are hydrocarbons—in the same family of molecules as natural gas and crude oil, composed exclusively of carbon and hydrogen. Ethane, propane, butane, isobutane, and pentane are all NGLs (see table above). There are many uses for NGLs, spanning nearly all sectors of the economy.
Hydrocarbon Liquids and Their Uses Depending on who you talk to, the definition of “hydrocarbon liquid” may vary. Some educators may try to limit the label to crude oil, preferring to use more specific terms for liquid hydrocarbons transitioned from a gas state instead, including “condensate” and “natural gas liquids” (NGLs).
A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.
Liquid mercury is a part of popular secondary reference electrode (called the calomel electrode) in electrochemistry as an alternative to the standard hydrogen electrode. The calomel electrode is used to work out the electrode potential of half cells.
Milk is a white liquid produced by the mammary glands of mammals. It is the primary source of nutrition for infant mammals (including humans who are breastfed) before they are able to digest other types of food. Early-lactation milk contains colostrum, which carries the mother's antibodies to its young and can reduce the risk of many diseases.
Liquid nitrogen and liquid oxygen are extremely cold. These materials are capable of causing severe frostbite. Avoid skin contact with these liquids. Also, take care to avoid touching any object which has been in contact with the cold fluids, since it may also be very cold.
What is Urine? At its most basic definition, urine is a liquid or water waste product that passes through your urinary tract and is expelled from your body through your urethra. For a male, the urine exits the urethra at the tip of the penis, and for a woman, the urine exits the urethra opening located south of the clitoris and north of the vagina.
Liquid oak is an extraction from oak which is available in liquid form used as an oak substitute. It is used to instantly add oak characteristics to a finished wine. As this is a more inexpensive alternative to using oak barrels, it is often used for lesser quality wines.
