Shows the number and type of atoms present in the smallest representative unit of a substance?
The smallest representative unit of a substance is called a molecule. The number and type of atoms present in a molecule are determined by the chemical formula of the substance. The chemical formula provides information on the number and type of each element present in the molecule.
What is the chemical equation for NaCl?
Sodium chloride is a compound; a compound has a chemical formula (or a formula unit) not a chemical equation. The formula unit of sodium chloride is NaCl.
What represent a molecular compound?
This is the chemical formula (empirical formula) or the formula unit of this compound.
What is the formula unit for the iconic compound barium sulfate?
This chemical formula is BaSO4.
Does the chemical formula P2O5 represent a molecule or a formula unit?
The chemical formula P2O5 represents a formula unit. This is because P2O5 is an ionic compound, consisting of a combination of phosphorus and oxygen ions in a fixed ratio.
Why NaCl is formula unit?
NaCl is considered a formula unit because it represents the smallest whole number ratio of ions in a crystal lattice of sodium chloride. The formula unit represents the simplest unit of a compound that still retains its chemical properties.
NaCl is not a molecule but a formula unit?
Yes, it is correct - NaCl is a formula unit of sodium chloride; ionic compounds hasn't a true chemical formula.
The elements that make up a compound and the exact number of atoms of each element in a unit of the compound can be?
determined using the chemical formula of the compound. The chemical formula provides the type and ratio of elements present in a compound. After determining the chemical formula, one can calculate the exact number of atoms of each element in a unit of the compound using stoichiometry.
What the symbols and number mean in the chemical formula of an ionic compound?
Symbols are the chemical symbols of elements.Number are the number of a specific atom in the molecule or formula unit. For example: Na2SO4- Na, S, O are the chemical symbols of sodium, sulfur and oxygen- 2 is the number of sodium atoms in the formula unit; 4 is the number of oxygen atoms in the formula unit
Is MgO an ionic compound?
NaCl is the chemical formula unit of sodium chloride. MgO is the chemical formula of magnesium oxide.
A chemical formula tells what make up a and the exact of atoms of each element in a unit of compound?
Yes, a chemical formula represents the types of atoms and the number of each type of atom in a single unit of a compound. It provides the ratio of different elements present in the compound. The formula also helps in determining the properties and behavior of the compound.
What is the sodium formula unit for sodium chloride?
