2  A chemistry equation is a short, easy means to show a chemistry reaction using symbols instead of words.  A reactant is the problem you have at the beginning of the reaction.  A product is the new substance the formed throughout the reaction.

*

3  The principle of conservation of mass states that in a chemical reaction, the total mass of the reactants have to equal the complete mass of the products.

*

4  compose the equation. › H 2 + O 2 H 2 O  count the atoms. › H 2 + O 2 H 2 O › 22 2 1

*

5  use Coefficients to Balance Atoms. › 2_H 2 +__ O 2 2_ H 2 O › 4 2 4 2  Look ago and check › The left and also right sides of the equation need to be equal.

*

6  synthetic – 2 or much more elements incorporate to do a more facility substance.  Decomposition – compound are damaged into simpler products.  instead of – as soon as one element replaces an additional in a compound
