The compound produced when oxygen combines with an alkali metal is typically the alkali metal oxide, which has the formula MO.
When acetic acid combines with n-octyl alcohol, the smell produced is usually a fruity or floral scent. This combination forms esters, which are commonly used in perfumery to provide pleasant fragrances.
The last part in the chemical formula of a binary ionic compound is usually the anion, which is negatively charged and is represented by its element symbol. It is written after the cation in the formula to show the complete chemical composition of the compound.
I should point out that ammonium usually combines with chlorine in a one to one ratio, as ammonium chloride (NH4Cl), not ammonium dichloride (NH4Cl2).
A salt and usually some other substance, most often water, is produced.
That is partially correct. When naming a binary molecular compound, you add the suffix -ide to the second element in the formula, regardless of its ionic nature. The more electronegative element is usually listed first in the compound formula.
When only potassium and oxygen, the compound usually formed has the formula K2O. Under certain conditions, a compound with formula K2O2 can also be formed.
Pure fluorine usually exists as a diatomic compound, formula F2.
Dinitrogen. But usually just nitrogen molecule.
When acetic acid combines with n-octyl alcohol, the smell produced is usually a fruity or floral scent. This combination forms esters, which are commonly used in perfumery to provide pleasant fragrances.
If it is a molecular compound, the smallest unit is called a molecule. If it is an ionic compound, the smallest unit is called a formula unit.

Oxygen does not have a subscript since it is an element. Subscripts are usually found in the chemical formula of a compound and not an element.
A salt and usually some other substance, most often water, is produced.
The empirical formula of the compound formed between magnesium and fluorine is MgF2. This is because magnesium has a 2+ charge and fluorine has a 1- charge, so one magnesium ion will combine with two fluorine ions to achieve a neutral compound.
A chemical formula or molecular formula is a way of expressing information about the atoms that constitute a chemical compound.So this being said, that basically means the chemical formula represents the atoms that are bonded to one another (An atom is classified according to chemical element and isotope more specifically)
depends, an Empirical formula will always (by definition) show the ratio in which atoms are combined within a molecule. a molecular formula on the other hand shows the number of atoms of each element in a molecule, the only exceptions being massive structures, crystal latices and where a molecular formula cannot be produced and is either given in the form n*(empirical formula) or just the empirical formula. do note however that reference to a formula of a molecule usually refer to the molecular formula except in the exceptions listed above.
