Binary salts and oxygen react to produce a chlorate. The first two substances are metallic oxides and the last two are nonmetallic oxides. O are the products of an acid decomposing. If this oxidation number business is unknown to you, the only other way is to memorize a set of reactions. 2 SO 4 and so on.
Problems Note that none of the example problems above are balanced.
Your teacher may require this, but the ChemTeam will only provide some of the following answers balanced. Write correct formulas for the products in these synthesis reactions.
