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
