What are the 2 main parts of a chemical equation?

Answer 1

The two parts of any chemical formula are the element symbols and their subscripts. For example, the water molecule is made of two atoms of Hydrogen and one atom of Oxygen; therefore its chemical formula will be H2O, where H and O are the symbols of the elements involved and the 2 is a subscript, telling how many atoms are present of the element preceding it. Oxygen, having only one atom in a water molecule is left as O with no subscript because it is understood that if you have the symbol there, then at least one atom of that element is present. Here is another example: the formula for glucose is C6H12O6, so there are 6 Carbon atoms, 12 Hydrogen atoms, and 6 Oxygen atoms in one molecule of glucose.

Answer 2

The two main sections of a chemical equation are separated by the equal sign.

To the left of the equal sign are the reactants, the substances existing before a reaction.

To the right of the equal sign are the products, the substances existing after a reaction.

Answer 3

The two parts is the reactants and the products.

Answer 4

The reactants go on the left side of the arrow, the arrow goes in the middle, and the products go to the right of the arrow.

Answer 5

Reactants and Products
