2024年12月9日 · Carbon dioxide, a colorless gas having a faint sharp odor and a sour taste. It is a greenhouse gas, but it is a minor component of Earth’s atmosphere, formed in combustion of carbon-containing materials, in fermentation, in respiration of animals, and employed by plants in the photosynthesis of carbohydrates.

2025年3月13日 · : a heavy colorless gas CO2 that is formed especially by the burning and breaking down of organic substances (as in animal respiration), is absorbed from the air by plants in photosynthesis, and has many industrial uses.

Carbon dioxide is a chemical compound with the chemical formula CO 2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature and at normally-encountered concentrations it is …

CARBON DIOXIDE definition: 1. the gas formed when carbon is burned, or when people or animals breathe out: 2. the gas formed…. Learn more.

Carbon dioxide is a chemical compound composed of one carbon and two oxygen atoms bonded together. It is one of the important ingredients in photosynthesis, the process by which green plants prepare food and energy. It is a colourless, odourless gas and is …

Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. However, an increase in CO 2 concentrations in our atmosphere is causing average global temperatures to …

2022年2月24日 · Carbon Dioxide Definition. noun, car·bon di·ox·ide, /daɪˈɒksaɪd/ (biochemistry) An inorganic compound, with the chemical formula, CO 2, composed of two oxygen atoms linked to a single carbon atom by a covalent bond, and essential to …

A colorless, odorless gas that is present in the atmosphere and is formed when any fuel containing carbon is burned. It is breathed out of an animal's lungs during respiration, is …

Carbon dioxide (CO 2) is the primary greenhouse gas emitted through human activities. Proteins, lipids, nucleic acids, and carbohydrates are all made up of carbon as the primary part. Carbon’s molecular structure allows it to form bonds with a variety of elements in a variety of ways.

2024年7月11日 · Carbon dioxide, often abbreviated as CO₂, is a covalent compound made of carbon and oxygen. In simpler terms, it’s a kind of gas that forms when carbon atoms bond closely with two oxygen atoms. This bonding happens in a special way called covalent bonding, where the atoms share electrons with each other.
