What is a combination of symbols and numbers that describes a molecule?
A combination of symbols and numbers that describes a molecule is called a chemical formula. It represents the types of atoms present in the molecule and their respective ratios. The symbols represent the chemical elements (e.g., H for hydrogen, O for oxygen) and the numbers indicate the number of atoms of each element in the molecule. Chemical formulas are essential for understanding the composition and structure of molecules in chemistry.
What does a chemical compound formula tell you?
It tells what elements are present in a molecule and how many atoms of each element are present.
How many atoms are present in the formula for propane?
The chemical formula of propane is C3H8; 11 atoms are present in the molecule.
A chemical formula used to show the number and types of atoms present in a molecule is referred to as what?
A chemical formula that shows the number and types of atoms in a molecule is known as a molecular formula. Molecular formulas are written by writing the symbol for each element followed by a subscript to show the actual number of atoms in the molecule.
What does a chemical formula communicate?
A chemical formula shows the composition of a substance. It shows the elements present and their relative numbers. There are several types of formula which give specific types of information, but that's the basics.
What does the subscript indicate in the chemical formula?
The number of atoms of that element in the molecule

A molecule of alkene has the chemical formula C3H4. How many carbon-carbon double bonds are present in the molecule?
One carbon-carbon double bond is present in a molecule of alkene with the chemical formula C3H4.
What information about a molecule does a chemical formula give you?
A chemical formula provides information about the types and numbers of atoms present in a molecule. It tells you the elements that make up the molecule and their ratios.
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.
Which is not true about the chemical formula of a substances?

What does a chemical compound formula tell you?
It tells what elements are present in a molecule and how many atoms of each element are present.
What part of the chemical formula indicates the number or molecules or atoms involved?
coefficients
How many atoms are present in the formula for propane?
The chemical formula of propane is C3H8; 11 atoms are present in the molecule.
What is a symbol that shows the elements in a compound and the ratio of atoms?
You think probable to the chemical formula of a molecule.
Describe the meaning of the subscripts in the formula for glucose C6H12O6?
The subscripts in the formula for glucose, C6H12O6, indicate the number of each type of atom present in one molecule of glucose. In this case, there are 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.
What is a number in a chemical formula that tells the number of atoms in a molecule called?
The number that tells the quantity of atoms in a molecule is known as a subscript. These numbers are located to the right of the element's symbol in a chemical formula. Subscripts are used to indicate the specific ratio of each type of atom present in the compound.
