Worksheet #1 COMPOSITION (SYNTHESIS) REACTIONS IF TIE REACTANTS ARE: a. no elements 6. one element and a compound containing that element e, water and a metal oxide d. water and a nonmetal oxide ... you probably have a composition reaction. GENERAL EQUATION: A + B > AB [ Element, + Element; > Compound | APPLY THES! ES TOC $ metal + nonmetal => salt nonmetal oxide (acid anhydride) + water => ternary acid (main versions) metal oxide (basic anhydride) + water => metal hydroxide metal chloride + oxygen = metal chlorate nonmetal oxide + metal oxide => salt (with polyatomic inn} metal oxide + carbon dioxide = metal carbonate . compound + element already in compound => compound w/ element at higher oxidation state note: oxidation numbers never change unless rule 7 applies! 8. metal + oxygen => metal oxide AaWsee STATES OF MATTER IN COMPOSITION REACTIONS: nonmetal oxides (g) metal oxides (s) salts (s) water (I} acid (aq) individual elements (look at periodic chart for state) if one reactant is water, then the praduct could be aqueous (aq) THE DIATOMICS: H, Nz, 02, Fz, Ch, Br2, i DIRECTIONS; Determine the products of each reaction and balance the equation. Indicate all states. Place the rule number for each ta the right af each problem, Use the main version of the ion.
