H20 (water) H being hydrogen, and O being oxygen
but then again, you probablly allready had to hand in this homework, so for future refrence, study!
It tells what elements are present in a molecule and how many atoms of each element are present.
A combination of chemical symbols that show what elements make up a compound and the number of atoms of each element in the smallest unit of the compound is a chemical formula.
Ammonia is a compound. It consists of the elements nitrogen and hydrogen. In one ammonia molecule, there is one nitrogen atom and three hydrogen atoms. The chemical formula for ammonia is NH3.
A chemical formula shows the elements in the compound and the ratio of atoms. For example, the chemicals formula for carbon dioxide is CO2 . In the carbon dioxide, there are always two oxygen atoms to every one carbon atom.
I count four elements: calcium, hydrogen, phosphorus, and oxygen.
You think probable to the chemical formula of a molecule.
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
The ratio and types of elements in the compound.
It tells what elements are present in a molecule and how many atoms of each element are present.
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
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.
A combination of chemical symbols that show what elements make up a compound and the number of atoms of each element in the smallest unit of the compound is a chemical formula.
The chemical formula for this is Fe3N2. The elements making this compound are nitrogen and ferrous. It has 3 ferrous atoms and 2 nitrogen atoms.
a chemical formula is a force that holds atoms together in a compound.
Ammonia is a compound. It consists of the elements nitrogen and hydrogen. In one ammonia molecule, there is one nitrogen atom and three hydrogen atoms. The chemical formula for ammonia is NH3.
A chemical formula tells what elements make up a compound and the exact number of atoms of each element in a unit of compound. :)
