Is formaldehyde CH2O and acetic acid C2H4O2 have the same empirical formula but different?
The empirical formula is similar.
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.
Two compounds have the same empirical formula do theynecessairily have the same molecular formula?
No? Consider starch and cellulose; same formula extremely different properties.
Can an empirical formula be triple its molecular formula?
Yes, it is possible for an empirical formula to be the same as the molecular formula. For example, Lactic acid's molecular formula is C3H6O3, which would make its empirical formula CH2O.
How are the empirical and molecular for a compound related?
A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.
Why is it possible for different covalent compounds to have the same empirical formula?
Isomerism. The structures of the molecules are different even when the numbers of atoms are the same. Organic molecules are the most common examples of this. Compare n-butane and iso-butane same formula different structures. See link
Is formaldehyde CH2O and acetic acid C2H4O2 have the same empirical formula but different?
The empirical formula is similar.
The lowest whole number ratio of the elements in a compound is called the?
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
What formaldehyde CH2O and acetic acid C2H4O2 have the same empirical formula but different?
Empirical formula is a useless notion; important is the molecular formula.
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.
Two compounds have the same empirical formula do theynecessairily have the same molecular formula?
No? Consider starch and cellulose; same formula extremely different properties.
What is the empirical formula for K3PO4?
In this case, the empirical formula and the molecular formula are the same and it is K3PO4.
What empirical formula of sodium nitrate?
In this instance, the empirical formula is the same as the formula unit: NaNO3
Formaldehyde and acetic acid have the same empirical formula but different?
These two compounds has different molecular formulas.
Does CO2 and SO2 have the same empirical formula?
No, Compounds with the same empirical formula have the same elements in the same ratio. SO2 and CO2 contain different elements. SO2 is a compound of sulfur and oxygen while CO2 is a compound of carbon and oxygen.
Does C7 H14 and C10 H20 have the same empirical formula?
Yes, they have. Empirical Formula is the simplest formula of a compound. For both C7H14 and C10H20 the Empirical formula is CH2 .
It is possible for different covalent compounds to have the same empirical formula because empirical formulas represent?
Empirical formulas represent the simplest component of a molecule.
