Because carbon cannot be changed into a simpler substance by normal means
Sugar does not appear on the periodic table, because it is not a chemical element. Rather it is a chemical compound consisting of multiple elements: carbon, hydrogen, and oxygen. For example, table sugar (sucrose) has a chemical structure of C6H12O6.
Pure antimony is a pure element. No element can be broken down into a simpler substance by any means. Molecules and compounds that contain antimony, however, can easily be broken down into the pure element.
Air is a mixture of different gases, including nitrogen, oxygen, carbon dioxide, and others, rather than a compound or element. It is not a pure substance but a combination of gases that makes up Earth's atmosphere.
Come on, are you daft? Look at the periodic table. 'C' is for carbon, not capsaicin. Capsaicin is a fairly complex chemical compound: (CH3)2CHCH=CH(CH2)4CONHCH2C6H3-4-(OH)-3-(OCH3) ) It is mostly carbon and hydrogen, with a little oxygen and nitrogen.
Sodium hydroxide is an a compound; not an element. As such it has a formula rather than a symbol: NaOH.
Carbon Dioxide is a compound formed by a Carbon and Oxygen. Only an element can be classified as a metal, non-metal or a metalloid. Compounds cannot be classified in these categories. Carbon and oxygen both are non-metals.
Dry ice is not an element. Dry ice is solid carbon dioxide, CO2, which is a compound.
In its pure form it is a compound: sulphuric acid. But usually it is a mixture of sulphuric acid and lead sulphate.
Sugar does not appear on the periodic table, because it is not a chemical element. Rather it is a chemical compound consisting of multiple elements: carbon, hydrogen, and oxygen. For example, table sugar (sucrose) has a chemical structure of C6H12O6.

Plastic is a mixture of different compounds, additives, and polymers that are combined to give it its properties. It is not a single compound or element, but rather a complex mixture of several substances.
Pure antimony is a pure element. No element can be broken down into a simpler substance by any means. Molecules and compounds that contain antimony, however, can easily be broken down into the pure element.
No, Antoine Lavoisier is not correct to refer to charcoal as an element. Charcoal is not an element but rather a compound primarily composed of carbon. An element is a substance that cannot be broken down into simpler substances by chemical means, whereas a compound is composed of two or more elements chemically bonded together. Lavoisier's understanding of elements and compounds was foundational in the development of modern chemistry.
No. It is not. Iron is an element. Oxygen is an element. Iron Oxide is a compound.
Hemoglobin is a protein molecule found in red blood cells that consists of elements such as iron, carbon, hydrogen, and oxygen. Therefore, hemoglobin is a compound rather than an element, as it is made up of multiple elements chemically bonded together.
Air is a mixture of different gases, including nitrogen, oxygen, carbon dioxide, and others, rather than a compound or element. It is not a pure substance but a combination of gases that makes up Earth's atmosphere.
During a chemical reaction, the powder breaks down into calcium and carbon.
