What do molecular formulas and structural formulas have in common?
Molecular formulas contain no information about the arrangement of atoms. Because of this, one molecular formula can describe a number of different chemical structures. A structural formula is used to indicate not only the number of atoms, but also their arrangement in space.
Octane and methane are both carbon and hydrogen atoms why are they different?
Octane and methane are both saturated hydrocarbons and follow the formula CnH2n+2. The only thing that's different is the number of carbons (and hence hydrogens) in the backbone. Octane has 8 carbons and has formula C8H18. Methane has 1 carbon and has formula C1H4.
Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
A carbon molecule that has a different arrangement of atoms is know as?
A carbon molecule that has a different arrangement of atoms is know as an isomer. I just took the test!
Does isomers differ in charge?
Isomers can have the same or different charge depending on their molecular structures. Isomers with different connectivity or arrangement of atoms might have different charges due to variations in the distribution of electrons. However, isomers with the same molecular formula but different structural arrangements will have the same overall charge.
Which is the correct molecular formula if the molecule has 6 carbons?
The correct molecular formula if a molecule has 6 carbons is : C6. The 'C' is the symbol for carbon and the little '6' tells us that there are 6 carbons in a particular molecule.
How do you write the formula of a monosaccharide that has three carbons?
The general formula for a monosaccharide with three carbons is C3H6O3. One example of a monosaccharide with three carbons is glyceraldehyde, which has the molecular formula C3H6O3.
What is the order of atoms in the molecular formula of the compound?
The order of atoms in a molecular formula indicates the arrangement of different elements in a compound. The molecular formula provides information about the types and numbers of atoms present in a molecule.
Formaldehyde and acetic acid have the same empirical formula but different?
molecular structures. The molecular formula of formaldehyde is CH2O, while acetic acid has the molecular formula CH3COOH. Despite having the same empirical formula, their arrangement of atoms is different, resulting in distinct chemical properties.

What would be the molecular formula for an alkane with 43 carbons?
Well... It seems to be C43H88 which is TRITETRACONTANE.Hope this helped!
How many carbons are in alpha-ketoglutarate?
The molecular formula is C5 H6 O5 so it it has 5 carbons.
Do A molecular formula show the arrangement of the atoms in a molecule?
Yes.

How many elements of unsaturation do molecules with a molecular formula of c6h6cl6 have?
Molecules with a molecular formula of C6H6Cl6 have 7 elements of unsaturation. This is calculated using the formula: E = 1 + (number of carbons) - (number of hydrogens) / 2 + (number of nitrogens) + (number of halogens).
