Would ionic or covalent molecules use the molecular formula or empirical formula?
What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.
How do you write lead IV hydroxide?
The chemical formula of lead(IV) chromate is PbCrO4.
Why some compounds have molecular and empirical formula?
The concept of empirical formulas apply to ionic compounds. You write the action first, the anion second, and use the minimal amount of atoms possible to make a neutral compound. A molecular formula would be the formula without necessarily the minimum amount of atoms.
What is the formula unit of molecular compounds?
The molecular formula is the formula of a discrete (single) molecule of the substance.The formula unit is generally defined in the same way as the empirical formula, which is the simplest whole number ratio of the elementsChemical formula includes both molecular and formula units.Examples:-Benzene a molecule consisting of a ring of 6 carbon atoms each with a hydrogen attached:-molecular formula C6H6formula unit CH (which is the result you would get if you analysed the compound and worked out the atomic ratio of carbon to hydrogen.NaCl is ionic so you cannot write a molecular formula you express the compound simply as the formula unit (empirical formula)- in its simplest case NaCl (never Na2Cl2 or some such)How can you tell whether a formula is molecular formula or a formula unit. Well if the formula could be "simplified" like benzene C6H6 could be simplified to CH then you know its a molecular formula. Something like SO2 and TiO2, well you need to be told. (SO2 is molecular, TiO2 is ionic)
What is the chemical symbol for nickelII?
Nickel(II) is the plus two (+2) oxidation state of nickel (Ni), and we write it Ni(II) or Ni++ when we set it down.

What is a quick way of showing the chemical composition of a compound?
draw a structural formula for organics, write a chemical formula (molecular formula or ionic formula) for simpler compounds.
What is a quick way of showing the chemical composition in a compound?
draw a structural formula for organics, write a chemical formula (molecular formula or ionic formula) for simpler compounds.
