What is a chemical formula that shows the numbers and kinds of atoms in a molecule but is not the arrangement of the atoms?
A molecular formula shows the numbers and kinds of atoms in a molecule but not the arrangement of the atoms.
Capital or small case letters that represent numbers?

Which formula shows the number and types of atoms in a molecule but not the bonds?
A molecular formula shows the types and numbers of atoms in a molecule, but not the bonds. A structural formula shows the way in which the atoms bond.
What do the numbers and letters in the chemical formula for water tell you about water?
The molecular formula for a water molecule tells you the numbers and kinds of atoms in a molecule. For example, the formula H2O means that one molecule of water contains two hydrogen atoms and one oxygen atom.
What are lowered numbers in a compounds formula?
The lowered numbers are called subscripts, and represent either the number of atoms of the element they follow in a molecular formula, or the ratio of ions in an ionic compound. For example, the molecular formula for a water molecule, H2O, indicates that there are two hydrogen atoms and one oxygen atom per molecule. Also, the formula unit for the ionic compound calcium chloride, CaCl2, indicates that in the ionic compound, the ratio of calcium ions to chloride ions is 1 to 2.
A branch of mathematics that use letters to represent numbers called what?
It is algebra that uses letters to represent numbers and also Roman numerals.
What do letters and number represent in Microsoft Excel?
They can represent values in cells. They also can represent columns (letters) and rows (numbers).
Which formula shows the numbers and types of atoms in a molecule but not the bond?
The molecular formula shows the numbers and types of atoms in a molecule, but not how they are bonded. The structural formula shows how the atoms are bonded.
What is literal numbers?
Literal numbers are the letters which are used to represent a number.
What is a chemical formula that shows the numbers and kinds of atoms in a molecule but is not the arrangement of the atoms?
A molecular formula shows the numbers and kinds of atoms in a molecule but not the arrangement of the atoms.
Do Roman numerals have anything to do with algebra?
No, they do not. Although it is using letters to represent numbers, Roman numbers are fixed symbols, unlike letters in algebra which represent variables.
What is the combination of letters and numbers used to represent a substance?
A molecular formula contains the atomic composition by element and their quantities. For example H2O is the molecular formula for water. The formula indicates that there are two atoms of hydrogen (H) and one oxygen (O) in each water molecule. Through the molecular formula molar mass can further be derived. In the case of water is 18-grams per mole.
How do you understand algebraic expression?

How do you convert letters to numbers?
There are many different systems of using numbers to represent letters. Binary is commonly used.
