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.
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.
A substance can be a mixture or solution, rather than a compound. These do not require that the separate substances combine chemically. An element is a substance that has only one type of atom.
No, KI (potassium iodide) is not a salt. It is a chemical compound that contains the elements potassium and iodine. While it does have an ionic bond, it is more accurately classified as an inorganic compound rather than a salt.

Carbon is an element because by itself, it cannot be broken down into any simpler substances through chemical means. It appears in the Periodic Table of Elements and has atomic number 6. Carbon dioxide, calcium carbonate, and tetrachloromethane would be examples of carbon-containing compounds.
Infact it is not an element but rather a molecule..
During a chemical reaction, the powder breaks down into calcium and carbon.
Cobalt, the transition metal, is an element. It's element number 27, and it does not occur naturally as an element or as a mixture, but rather as a compound. Links are provided.
Seawater is neither a compound nor an element but a mixture including much dissolved solid and usually microorganisms as well.
Nitrogen,N2
No Copper is a chemical element rather than a compound.
No, but compound is rather chemical combination of two more element
No, it's not an element. HCI would a compound consisting of Hydrogen, Carbon and Iodine, which are elements. However, HCI does not exist, but HCl (with a lowercase L) does. It is not an element, it is a compound consisting of hydrogen and chlorine, commonly known as hydrochloric acid.

Fe2(SO4)3, iron (III) sulfate, is not an element but rather a compound.
