general equations

• Substance + oxygen --> oxides
• Metal + water --> metal hydroxide + hydrogen
• Metal + acid --> salt + hydrogen
• Metal oxide + acid --> salt + water
• Metal hydroxide --> salt + water
• Metal carbonate + acid --> salt + water + carbon dioxide
• Metal hydrocarbonate + acid --> salt + water + carbon dioxide
• Ammonia + acid --> ammonium salt
• Metal carbonate --> metal oxide + carbon dioxide
• acid + base --> salt + water
• acid + carbonate --> salt + water + carbon dioxide
• Acid + alkali ---> salt + water
• H+ + OH- --> H2O
• metal carbonate --> metal oxide + carbon dioxide

  thermal decomposition
• H+ + HCO3- --> H2O + CO2
