How many elements are in a molecule of calcium carbonate (CaCO3)?
Three elements; the metal calcium in the positive portion of the compound, and the elements carbon and oxygen in the negative carbonate radical.
How are subscripts used in a compound?
Subscripts in a compound are used to indicate the number of atoms present for each element in the compound. They show the ratio at which the elements are combined to form the compound. Each subscript number represents the number of atoms of the element that follows it.
List the number of atoms for each element in this compound CaCO3?
Calcium (Ca): 1 atom Carbon (C): 1 atom Oxygen (O): 3 atoms
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.
What are the elements in CaCO3 and HCI?
CaCO3 is composed of calcium, carbon, and oxygen atoms. HCl is composed of hydrogen and chlorine atoms.
What is the least number of atoms in a compound?

An example of a compound that has matter?
Calcium carbonate (CaCO3) is a chemical compound and is matter.
How many o atoms are present in 50gram of caco3?
There are 2 oxygen atoms in one molecule of CaCO3. To calculate the number of oxygen atoms in 50 grams of CaCO3, you first need to find the number of moles of CaCO3 using its molar mass. Then, multiply the number of moles by the number of atoms of oxygen per molecule of CaCO3 (2) to find the total number of oxygen atoms.
Elements a compound contains and the exact number of the atoms of each element in a unit of that compound is called what?
