Well, believe it or not, atoms are even tinier than that! Sometimes, atoms come together to form elements, which is something that cannot be broken down any further, as it is already in its simple form. Carbon and oxygen are examples of elements. When one carbon and two oxygen come together the compound called carbon dioxide is formed.
When two oxygen molecules come together, what is the compound called?
When one carbon and two oxygen come together the compound called carbon dioxide is formed. Compounds are when more than one element combines to create something new. Carbon dioxide is one of the most common compounds in the world. You can't see it.
What are the properties of carbon dioxide?
The properties of carbon dioxide were studied by the Scottish scientist Joseph Black in the 1750s. Carbon dioxide is a greenhouse gas. Greenhouse gases trap heat energy. Greenhouse gases change the climate and weather on our planet, Earth. This is called climate change.
What is carbon dioxide made of?
It is made of one carbon and two oxygen atoms. People and animals release carbon dioxide when they breathe out. Also, every time something organic is burnt (or a fire is made), it makes carbon dioxide. Plants use carbon dioxide to make food. This process is called photosynthesis.
How is carbon dioxide produced?
Industrial carbon dioxide is produced mainly from six processes: 1 By capturing natural carbon dioxide springs where it is produced by the action of acidified water on limestone or dolomite. 2 As a by-product of hydrogen production plants, where methane is converted to CO 2; 3 From combustion of fossil fuels or wood; 4 As a by-product of fermentation of sugar in the brewing of beer, whisky and other alcoholic beverages; 5 From thermal decomposition of limestone, CaCO3, in the making of lime ( Calcium oxide, CaO );
What is CaO in gas?
Quicklime (CaO), a chemical that has widespread use, can be made heating limestone to about 850 °C. This reaction also makes CO 2 : Carbon dioxide is also made in the combustion of all carbon-containing fuels, such as methane ( natural gas ), petroleum distillates ( gasoline, diesel, kerosene, propane ), coal or wood.
What is the process of respiration?
This is a process known as cellular respiration. This includes all plants, animals, many fungi and some bacteria. In higher animals, the carbon dioxide travels in the blood from the body's tissues to the lungs where it is breathed out. Plants take in carbon dioxide from the atmosphere to use in photosynthesis .
What is the predominant form of bicarbonate?
In neutral or slightly alkaline water (pH > 6.5), the bicarbonate form predominates (>50%) becoming the most prevalent (>95%) at the pH of seawater, while in very alkaline water (pH > 10.4) the predominant (>50%) form is carbonate. The bicarbonate and carbonate forms are very soluble.
