The atomic radius of C is 73 pm so if this, -, stands for a radius the chain looks like
-C-C-C-C-C-C-C-C-C-C-C-C-C-C-C-C-C-C- so take 19( - ) for (-)=73 and yopu get 1387 pm
Linear molecules all have 180 degrees between atoms

palytoxin is the longest carbon chain molicule consisting of 115 carbon atoms
A carbon dioxide molecule is made of 2 oxygen atoms and 1 carbon atom.
Gasoline is composed of a mixture of hydrocarbons having 6 to 9 carbon atoms, some linear some cyclic. The laboratory standard "gasoline" used for quality comparison is 100% pure linear octane (i.e. 8 carbon atoms). When burned in an engine with a shortage of oxygen, it does produce smaller hydrocarbons called "unburned hydrocarbons" that contribute to smog.
Linear molecules all have 180 degrees between atoms
The bond length (Distance between two carbon nuclei) decreases.

Such a carbon atom forms linear or digonal structure because it is 'sp' hybridized.
Linear
A carbon dioxide molecule is made of 2 oxygen atoms and 1 carbon atom.
Any hydrocarbon containing exactly 10 carbon atoms. It may be linear (default), branching, composed of aromatic rings, saturated, or unsaturated. But as long as it contains exactly 10 carbon atoms and nothing else but hydrogen atoms it is decane.
A good, common example would be carbon dioxide. In consists of a carbon atom with two oxygen atoms bonded on opposite sides.
Hexane is the alkane with six carbon atoms and is a linear molecule. Ethyl acetate CH3COOCH3 is an ester.
yes
The longer the carbon chain, it spreads out the atoms more equally which causes the carbon to get thicker and less runny.
