Ethane has one single bond between the two carbon atoms and 6 single bonds between the the carbons and hydrogens.
Bonds between two (adjacent) C atoms.
No, they are unsaturated as they contain double bonds
A carbon can form a maximum of four bonds.
Saturated fatty acids have no double covalent bonds between carbon atoms. The carbon in the chain is saturated with all the hydrogens it can hold. Saturated fatty acids account for the solid nature at room temperature of fats such as lard and butter. Unsaturated fatty acids have double bonds between carbon atoms wherever the number of hydrogens is less than two per carbon atom. Unsaturated fatty acids account for the liquid nature of vegetable oils at room temperature.
Ethane has one single bond between the two carbon atoms and 6 single bonds between the the carbons and hydrogens.
In an alkene with two carbon atoms being joined, there would be one double bond between the carbon atoms, and 4 single bonds for the 4 hydrogens, and it would be drawn as follows: H2-C=C-H2. This is ethene, and so it has a total of 5 bonds (unless you count the double bond as a sigma and a pi) then it has 6 bonds.
A fat molecule is made of a chain of carbon atoms making a "backbone" and a bunch of hydrogens along the outside. In a saturated fat, the carbon backbone has the maximum number of hydrogens it can accept. In an unsaturated fat, the carbon backbone has made one or more double bonds within the backbone and so have less than the maximum number of hydrogens around the outside.
Saturated means that a chemical compound has as many Hydrogens on each Carbon that "it can handle". Unsaturated means that there are places containing double bonds, triple bonds, etc., between the carbons resulting in the compound having less Hydrogens as it could have maximally. Usually all fatty acids have 1 or 2 degrees of unsaturation in their long carbon tails, usually in the form of double bonds.
Carbon atoms form covalent bonds with other carbon atoms, and with other nonmetals, such as carbon and oxygen, or carbon and hydrogen.
A double carbon bond is a covalent bond. Also carbon atoms can form double bonds. Carbon shares electrons with other atoms.
Bonds between two (adjacent) C atoms.
Polyethylene (C20H40) has single bonds from twenty carbon atoms to forty hydrogen atoms. It is a polymer chain of ten linked ethylene (C2H4) monomers, which have two carbon atoms and four hydrogen atoms. In an ethylene monomer, the two carbons are double bonded to themselves, while the hydrogens are single bonded to the carbons. When the ethylene monomers link to form Polyethylene, however, the bonds turn into all single bonds.
Carbon atoms are fixed into organic compounds in The Calvin Cycle.
Carbon will almost always form bonds with other carbon atoms, and that is part of what makes it such a useful element.
It depends on the atoms it is reacting with. If carbon it is 4 eg CH4 is methane, if oxygen it is two eg CO2 is carbon dioxide. This is because carbon can form four bonds, and carbon-carbon bonds are single bonds and carbon-oxygen bonds are double bonds.
The energy in a glucose molecule is stored in the bonds between the atoms.
