Document Summary

Chemical reactions: chemical reaction- arrangements of atoms, rxn=reaction the abbreviation we use for reaction in chemistry, chemical equation- chemical symbols to represent chemical reaction. Beginning part is reactant and second is product: reactant- what is being consumed in chemical reaction, product- what is being formed in the chemical reaction (s)- solid (g)- gas (l)- liquid (aq)- aqueous (dissolved in h2o) Not 2 chemical reactions: chemical or physical process, the change could be due to heat ( =change) Balancing equations: balancing equations, 2 +2 2, break down. 2 oxygen atoms: chemically bonded together. Examples: 22() + 2 22 (, total # atoms. 2: this is a balanced equation because there is the same amount of atoms on both sides, () + 2() (, add 2 in front of k and in front of. 2 () + 2() 2 (: 2 (s) + 2() 23(, add 2 in front of 23()
