Yes, they form the compound methane with the chemical formula CH4.
Hydrocarbons contain both Carbon and Hydrogen.
Ethanol
The letters represents the atom (or element) in the compound. In this case, there are carbon, hydrogen and oxygen atoms in this compound. The numbers behind the letters represents the number of each atoms in the compound. For the example, there are 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms in the compound. based on this, we can tell that the compound here is glucose (C6H12O6) since all compounds and elements have different chemical formula (also all those numbers and letters). The number in front of the first letter represents the number of such molecules/compounds. Since it is given as 6C6H12O6, we can deduce that there are 6 glucose molecules in it.
The combination of 4 hydrogen atoms and 1 carbon atom is a compound called methane, which has covalent bonds.
There are three elements in the chemical compound CH2O2. The three elements are: Carbon (C), Hydrogen (H) and Oxygen (O). In one molecule of this compound, there are 5 atoms: 1 Carbon atom, 2 Hydrogen atoms and 2 Oxygen atoms.
methane is a compound as one carbon atoms combines with 4 hydrogen atoms.
Carbon and Hydrogen atoms
Hydrocarbons contain both Carbon and Hydrogen.
Ethane
Butane is a compound that contains carbon and hydrogen atoms.
The chemical compound C3H3 has two element in it: Carbon and Hydrogen. In one molecule of this compound there are 6 atoms: 3 Carbon atoms and 3 Hydrogen atoms. Both elements in this compound, Carbon and Hydrogen are classed as other nonmetals. However this compound does not exist 'in real chemical life', it's a fantasy formula.
Yes.
A macromolecule made up of mainly carbon and hydrogen atoms that is primarily used for energy storage and in cell membranes.
Hydrocarbons
The given compound does not exist if there are twelve carbon atoms before hydrogen atoms then it will be the formula for sugar.
Ethanol
Salt is made from different atoms joined together. Water is a compound too; the atoms are Hydrogen x2 (H2) + Oxygen (O) = water (H2O). While carbon is a pure element. Baking soda is also a compound (NaHCO3)
