any alkane consists of a string of carbon molecules with covalent SINGLE bonds between adjacent carbon atoms. The carbon atoms are then single bonded to two hydrogen atoms each, and the carbon atoms on the end of the chain that are only bonded to one other carbon atom each get 3 hydrogens. so an alkane with 2 carbons gets 6 hydrogen, an alkane with 3 carbons gets 8, an alkane with 4 carbons gets 10, etc.
So the formula is CnH2n+2. This means if you have 'n' carbon atoms in the alkane, you have 2n+2 hydrogen atoms.

What is the chemical formula for an alkane with fifteen carbon atoms?
C15h32
What organic compound is an alkane?
Alkanes are saturated hydrocarbons with the general formula CnH2n+2.
Use the masses of carbon dioxide CO2 and water H2O to determine the empirical formula of the alkane component?
C3h7
What is the chemical equation of c3h8?
C3H8 is the chemical formula for a Alkane Hydrocarbon called Propane.It is highly flammable. It burns to form CO2 and H2O
Is it possible for an alkane to be an isomer of an alkene?
Yes, if the alkane is cyclic and the alkene is not.
What is the formula for alkane?
The generic formula for a non cyclic alkane is CxH(2x + 2).
What is the molecular formula of the simplest alkane capable of having constitutional isomers?
C4H10 is the simplest alkane formula C2H4 is the simplest alkene formula
What is the molecular formula for a 18 carbon alkane?
This alkane is n-octadecane with the chemical formula C18H38.
Is C5H12 an alkane?
Yes. The alkane series is the series of saturated hydrocarbons with the formula CnHn+2 .
What is the formula of an alkane with 16 carbons?
C16h34
What is the chemical formula for an alkane with 10 carbon atoms?
For a straight-chain alkane, this would be C10H22 - decane. However, if this is a cyclic alkane, you would have C10H20 (cyclodecane). There are also numerous options for a branching alkane with various names and carbon to hydrogen ratios.
What material is pentane?
Pentane is an alkane; its formula is C5H12.
Is methane a alkane?
no.all alkenes end with 'ene' .methane is not an alkene cause it does not end with 'ene'.it is an alkane cause it ends with 'ane'
Is the compound with the chemical formula C15H30 a member of the alkane series?
Alkanes have as general formula CnH2n+2 . C15H30 is therfore not an alkane it is an alkene (CnH2n) with one double bond.
What is the chemical formula for alkane which contains 125 carbon atoms?
The general formula of linear alkanes is CnH2n+2. If an alkane with 125 carbons exist (I don't know) the chemical formula will be C125H252 and the name pentacosehectane.
What is the chemical formula for an alkane with fifteen carbon atoms?
C15h32
Why is C6h14 an alkane?
Because alkanes follow the formula CnH2n+2 as 6*2+2=14, we can conclude c6h14 is an alkane
