A dashed line represents a hydrogen bond because they are the weakest of the bonds.
A single pair. :)
The lines in a structural formula represent the chemical bonds. These bonds are attractive forces between atoms that allow the formation of chemical substances.
The distance between centers of adjacent atoms
Saturated hydrocarbons have only single bonds between carbon atoms.
You can assume that those two atoms are covalently bonded to each other.
The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
The lines in a structural formula represent the chemical bonds. These bonds are attractive forces between atoms that allow the formation of chemical substances.
The covalent bond. One line is a single bond, two lines between atoms is a double bond and three lines is triple bond
The lines in a structural formula represent the chemical bonds. These bonds are attractive forces between atoms that allow the formation of chemical substances.

They mean the state boundaries boundaries
The distance between centers of adjacent atoms
The sharing of electrons between two atoms.
Usually they indicate the borders between the states.
Energy stored in the chemical bonds between atoms
Capital C followed by two parallel lines (=) then another capital C. C=C
If your director says 'Pick up your cue!' It means he/she wants there to be less space in between the lines. This doesn't mean saying your lines faster but just less empty silence between lines. For example, "Oh, Hello! My name is Millie!' (pause) "Hello there!" Is not what they want. They don't want that pause.
