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.
A chemical formula is a combination of symbols that shows the ratio of elements in a compound. Each element is represented by its chemical symbol, and the subscripts indicate the relative number of atoms of each element in the compound.
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
The ratio is called the chemical formula. Naming these compounds is called nomencalture. Example: NaCl sodium (Na) has a +1 charge and chlorine (Cl) has a -1 charge the charges cancel out and therefore the ratio is one to one Another Example: MgCl2 magnesium (Mg) has a charge of +2 and chlorine (Cl) has a charge of -1. It takes two chlorines to cancel out one magnesium so the ratio is one to two.
The empiracle formula shows the ratio of the individual elements in a compound, and the molecular formula shows the actual number of each elemental atom in each molecule (which will be equal to the empiracle formula or a whole number multiple of it). However, it is the structural formula that shows how the individual atoms are connected.
One way to prove water is a compound of hydrogen and oxygen is through chemical analysis. By breaking down water into its elements using electrolysis, you can separate hydrogen and oxygen gases, confirming their presence in water. Additionally, the molecular formula of water (H2O) represents the combination of hydrogen and oxygen in a fixed ratio.
The ratio and types of elements in the compound.
A chemical formula is a combination of symbols that shows the ratio of elements in a compound. Each element is represented by its chemical symbol, and the subscripts indicate the relative number of atoms of each element in the compound.
The subscripts in a chemical formula indicate the number of atoms of each element present in the compound. They show the ratio of the different elements in the compound's composition.

Compounds are represented in a formula unit to show the ratio of atoms present in the compound. This helps in identifying the elements involved and their quantities in a simple and concise manner. The formula unit provides information on the chemical composition of the compound.
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
The formula for zinc nitride (Zn3N2) indicates that there are three zinc atoms for every two nitrogen atoms in the compound. This ratio helps to show the combination of elements in a fixed proportion to form the compound.
The ratio is called the chemical formula. Naming these compounds is called nomencalture. Example: NaCl sodium (Na) has a +1 charge and chlorine (Cl) has a -1 charge the charges cancel out and therefore the ratio is one to one Another Example: MgCl2 magnesium (Mg) has a charge of +2 and chlorine (Cl) has a charge of -1. It takes two chlorines to cancel out one magnesium so the ratio is one to two.
The formula unit for an ionic compound shows the simplest ratio of ions in the compound. It represents the combination of ions that result in a neutral compound. The subscripts in the formula unit indicate the number of each ion required to balance the charges.
No, the chemical formula of an ionic compound does not show the atoms in a molecule. Instead, it represents the simplest ratio of ions in the compound. Ionic compounds exist as a lattice structure of alternating positive and negative ions, rather than discrete molecules.
It tells you what type of bonding whether; Ionic, Metallic, Covalent Network or Molecular Covalent. It tells you the elements that make up the compound. It also tells you the stage of matter; solid, liquid or gas. And since you known the elements you can find out really anything you want to know about it like; # of protons, # of neutrons, mass number, atomic weight, reactivity, etc.
Subscripts in a compound are used to indicate the number of atoms present for each element in the compound. They show the ratio at which the elements are combined to form the compound. Each subscript number represents the number of atoms of the element that follows it.
