A combination of chemical symbols and numbers to represent a substance?
The combination is known as a chemical formula.
A combination of chemical symbols and numbers that represent a substance is?
A shorthand representation of the composition of a substance using atomic symbols and numerical subscripts is called a chemical formula.
How many atoms are in C8H16?
24: The answer to the number of atoms present in a formula that does not include parentheses is always the sum of all the subscript numbers in the formula plus one for each type of atom shown without a subscript. If the formula does contain parentheses, all the subscript numbers inside the parentheses should be multiplied by the subscript number after the closing parenthesis itself before the sum of all subscripts is taken.
What does the subscript number stand for?
The number in the subscript of a chemical formula tells the number of that atom in a molecule. For example, in H2O, the 2 tells you there are 2 hydrogen atoms in the water molecule. in C3H8, there are 3 carbon atoms and 8 hydrogen atoms as reflected by the 3 and 8 in the formula respectively.
How are chemical formulas written do they use superscripts or subscripts?
Chemical formulas are written with the chemical symbol of each element followed by a subscript. If no subscript is written, it is understood to be 1. In a molecular formula, the subscripts indicate the number of atoms of each element that are present in one molecule. In a chemical formula for an ionic compound, the subscripts represent the lowest whole number ratio of ions in the compound.
what number represents the subscript in the formula shown?
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
Which is the term for numbers that appear in the chemical formula of some compound?
subscript

Chemical Formula
What does the subscript indicate in the chemical formula?
The number of atoms of that element in the molecule
What describes a substance using chemical symbols and numbers?
Well, no chemical can actually represent a substance with chemical symbols, but I think you're talking about a chemical formula.
How do you know if something is polyatomic?
In principle, only by comparing the chemical formula for the compound with the formulas of ions known to be polyatomic to determine whether the sequence of letters and subscript numbers (if any) in any part of the chemical formula corresponds to the sequence of letters and subscript numbers in the formula of a know polyatomic ion.

How does the chemical formula of a compound relate to the relative number of atoms in the compound?
Chemical formulas consist of chemical symbols and numbers. The symbols represent the elements in the compound. The numbers indicate the quantity of atoms of each element in the compound.
What are the numbers in a molecular formula?
The subscript numbers in a chemical formula indicate the number of atoms of the element they follow. No subscript means 1 atom. For example, H2O, or water, has 2 atoms and 1 atom of oxygen of hydrogen in each molecule. Or, in a more complex example a molecule of H2SO4, sulfuric acid, contains 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.
