Counting Atoms & Balancing Equations

Counting Atoms in a chemical formula A chemical formula is a description of the number and kind of atoms found in a single molecule of a substance, using the symbol for each element and a subscript number to state the number of atoms of the element to the left of the symbol. When a chemical formula has a coefficient you multiply the coeffiecient by all the atoms of each element on the molecule. 2 4 1 2 1 1 3 1 8 2 3 2 2 4 2 3 6 3 12 4 4 24 8 B U B B U U Balance the following equations. To do this, click on the radio button in front of each molecule and enter the coefficient value. Due to the constraints of this program, you will need to enter a 1 in the blank if there is only one molecule. 2 1 1 2 1 3 3 1 2 3 6 1 4 1 2 1 3 2 1 6
