Hydrocarbons are composed entirely of carbon and hydrogen.
hydrogen
carbon dioxide.
Organic substances contain carbon and hydrogen atoms. Organic compounds are formed by bonding carbon and hydrogen atoms. There can be more elements too. An atom can never be organic.
Oxygen, Carbon, Hydrogen. <- There are three new ones.
Yes, all is true.
they are carbonates as they are organuc substances and they contain carbon.
Substances with carbon-carbon or carbon-hydrogen bonds
Carbon and Hydrogen are both pure substances. They only contain Carbon and Hydrogen atoms respectively. Inside these atoms are protons, neutrons and electrons.
Elements.
hydrogen
Carbon and Hydrogen are always found in organic substances. By definition carbon is what makes something organic.
carbon dioxide, carbon monoxide, water.
Carbon
the chemical substances are carbon, oxygen and hydrogen.
All substances are MADE FROM elements but they are not elements. For example CH4 is made of one carbon atom and four Hydrogen atoms. Carbon and Hydrogen are pure elements but CH4 is not an element.
After carbon, The element having largest number of compounds is Hydrogen.
Carbon, Hydrogen, Oxygen.The amount of Carbon always equals the amount of Oxygen, and there is exactly twice as much Hydrogen as Carbon.
