Chemical reactions can be classified according to the chemistry of what is occurring during the reaction. Three common types of chemical reactions are precipitation rea reduction reactions, and acid-base reactions. - Part A Classify the following reactions as precipitation reactions, oxidation-reduction reactions, or acid-base reactions. Drag each item to the appropriate bin. ▸ View Available Hint(s) Cu(CH3COO)2(aq) + (NH4)2C2O4(aq) → CuC2O4(s) + 2NH4 CH3COO (aq) 4Al(s) + 302(g) → 2Al2O3(s) 2Hg(1) + O2(g) → 2HgO(s) Zn(s) + Ni2+(aq) → Zn2+(aq) + Ni(s) Mg(OH) 2 (s) + H2SO4(aq) → 2H2O(1)+ MgSO4(aq) NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(1) Sr(CH3COO)2(aq)+ (NH4)2SO4(aq) → SrSO4(s)+ 2NH4 CH3COO(aq) Precipitation Oxidation-reduction Acid-base ?
