A double bond is represented by two parallel lines. For example, the structural formula for CO2 is O=C=O.
C=O, on the aldehydic carbon.
Sucrose is a disaccharide comprised of glucose and fructose. While both glucose and fructose have double bonds, sucrose does not.
Each glucose molecule has the chemical formula C6H12O6. When three glucose molecules bond, they lose two molecules of water. The chemical formula of a trisaccharide made of three bonded glucose molecules is C18H32O16.
there is no double bond in butane
A trans isomer is when one group is above a double bond, and the other group is below the double bond. A cis configuration is when both groups are on the same side of the double bond.
If you're talking about formula like chemical formula (NaCl), there isn't one exactly, though sometimes a line is used (single line for a single bond, double line for a double bond, triple line for a triple bond). If you mean like a mathematical formula (LCAO or something similar), then Levine's Quantum Chemistry has a much more thorough treatment than we could possibly give here.

A double nonpolar covalent bond in the common kind with formula O2.

The bond indicated by the sign "=" in the formula, which in this instance is not an "equals" sign, is a double covalent bond between the two oxygen atoms.
A covalent bond that shares four electrons has a double bond between the atoms. A single bond is shown as a single dash, so a double bond is two dashes.
Glucose has covalent bonds.
The covalent bond. One line is a single bond, two lines between atoms is a double bond and three lines is triple bond
The bond is called a Glycosidic Bond
A glycosidic bond
