Which paraffin wax (including the in-betweens)?
2C20H42 + 61O2 -> 40CO2 + 42H2O
:
C25H52 + 38O2 -> 25CO2 + 26H2O
:
2C36H74 + 109O2 -> 72CO2 + 74H2O

∙ 12y agoWax is not a compound with a constant composition. An example of complete combustion of a compound that is a common constituent of paraffin wax is:
C21H44 + 32 O2 -> 21 CO2 + 22 H2O.

First balance Carbon to the right:
C40H82 + O2 --> 40 CO2 + H2O
Then balance Hydrogen to the right (this does not affest the former step):
C40H82 + O2 --> 40 CO2 + 41 H2O
After counting the O atoms at right side: 40*2 (in CO2) and 41*1 (in H2O), totalised 80+41=121
balance 121 O to the left with 121 / 2 = 60.5 O2
C40H82 + 60.5 O2 --> 40 CO2 + 41 H2O
and doubling ALL coëfficents to avoid 'halves' for the (idealised) balanced equation:
2 C40H82 + 121 O2 --> 80 CO2 + 82H2O

What is the chemical formula of wax explain it?
Wax is a class of compounds, not a single compound. Paraffin wax is a mixture of alkanes with carbon number around 20-40: C20H42 to C40H82.
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 is chemical formula for wax?
Paraffin wax is a colorless and translucent hard wax which is mainly composed of a mixture of alkanes. This mixture indicates solid straight-chain hydrocarbons with the general formula CnH2n+2.
What is a chemical compound known as paraffin?
Paraffin is a hydrocarbon, but the term applies to a "group" of molecules and not a specific one. The general formula applied to these alkanes is CnH2n+2, and the "series" of compounds begins with methane, CH4. In that example, there is a single carbon atom, and the number of hydrogens with it, according to the formula, is (2 x 1) + 2, or 4. After methane, we see ethane (C2H6), propane (C3H8) and onward, with all molecules following the "rule" suggested with the CnH2n+2 expression. If the inquiry is one regarding paraffin wax, this is not a single molecule, either. It is any one or a combination of the paraffin molecules with n between 20 and 40. That means the molecules with have a molecular formula including C20H42 and C40H82, and also those that are "between" these two. C21H44, C22H46, and the rest will appear on your list, if you're making one. In case you didn't snap to it, as we begin to examine this group of compounds we'll find substances that are a gas at room temperature. On up the chain we'll encounter some that are liquids at ordinary temperatures. Then the larger, heavier molecules we find even further up will be solids at room temperature.

What is the compound of carbon and hydrogen?
Hydrocarbons, if they contain only H and C.
