Do the subscripts in a chemical formula represent the relative mass of each atom in a chemical compound?
It usually represent the amount of atoms in a molecule, i.e. Na2CO3 + 2HCl --> 2NaCl + CO2 +H2O So, in the first compound, there are 2 sodium atoms, one carbon atom and 3 oxygen atoms. In water, there is one hydrogen atom and 2 oxygen atoms..
What is molecular mass?
the relative molecular mass or molecular weight of a compound is the mass of a molecule of the compound relative to the mass of a carbon atom taken as exactly 12.
What does the atomic mass of an atom represent?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Why can't you balance an equation by changing the subscripts of the reactants or the products?
You can't change the subscript. The subscripts show how the elements/molecules are bonded.--------------------------------------------------------------------------------------------------------The subscripts represent the number of atoms of each element in each chemical formula-if you change the subscripts, you change the compounds the formulas are describing.Source: (e2020)
Can a compound be a single atom of gold?
A compound can contain a single atom of gold, but a single atom of gold alone, by itself, cannot be a compound.

Notation using atomic symbols and subscripts to show the number of atom's of each element in a compound?

How do you express relative amounts of each element in a compound?
The subscripts indicate the amount of each element present in the compounds in a chemical equation. For example, H2O indicates that each molecule of water contains two atoms of hydrogen and one atom of oxygen. The lack of a subscript is understood to mean the number one. For an ionic compound, such as magnesium chloride, MgCl2, the subscripts indicate that each formula unit contains one magnesium ion and two chloride ions.
What does it mean when there are no subscripts in a formula?
No subscripts mean only one atom in formula. Example: KCl - 1 atom of potassium, 1 atom of chlorine.
What is molecular mass?
the relative molecular mass or molecular weight of a compound is the mass of a molecule of the compound relative to the mass of a carbon atom taken as exactly 12.
What are formulas for a compound with one calcium atom and two fluorine atoms and a compound with two aluminum atoms and three sulfur atoms?
Calcium fluoride is CaF2, and aluminium sulfide is Al2S3. All numbers should be subscripts.
Notation using atomic symbols and subscripts to show the element and the number of atom of each element in a compounds?
In the formula for a compound, you will see atomic symbols representing individual elements, and if needed, you will see subscripts that represent the number of those atoms required for that bonding scenario. Sodium chloride, for example is NaCl. You see the symbol for sodium followed by the symbol for chlorine. No subscripts are needed because sodium and chlorine combine in a 1-1 ratio. However, in aluminum oxide, the formula is Al2O3. Two aluminums are required for every three oxygens. The subscripts reflect that bonding ratio.
What is the total number of atoms of carbon in the formula K3FeCN6?
In chemical formulas, carbon atoms are denoted with the symbol C. Subscripts and superscripts denote the number of carbons. Since there is only one C and no subscripts or superscripts, the compound stated contains only one carbon atom.
Describe the meaning of the subscripts in the formula for glucose C6H12O6?
The meaning of subscripts in a chemical formula is to indicate the number of a given atom in the molecule.
What shows the relative number of atoms of each element in a compound.?
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
Can subscripts in a chemical formula be fractions?
The Subscripts in a Chemical formula explain how the atoms in that compound are chemically bonded. As a fraction of an atom cannot bond, the subscripts cannot be fractions. Coefficients, however which go before a chemical formula in chemical equations may be fractions. This is because they explain the ratio of the number of moles of each species required for the reaction and it is possible to have a fraction of a mole of something.

Is an atom smaller than a compound?
An atom is smaller than a compound because if an electron fits in an atom, and an atom is a part of a compound, it means a compound is bigger than an atom
