B. Heating of a metallic chlorate: a compound containing a metal and a ClO3 - ion Metal chlorate metal chloride + oxygen A metal chlorate always splits into a metal chloride and oxygen, no matter what the metal is. Prediction: Write the metal chloride and oxygen m(ClO3) mCl + O2 where m= metal Examples: K(ClO3) Mg(ClO3)2 KCl + O2 MgCl2 + O2 Potassium chlorate is a common ingredient in fireworks and safety matches. It is also commonly used in the lab in order to produce oxygen gas, which is otherwise expensive to get. Heating a metallic carbonate: a compound made of a metal and a CO3 - ion Metal carbonate metal oxide + carbon dioxide A metal carbonate always splits into a metal oxide and carbon dioxide, no matter what the metal is. Prediction: Write the metal oxide and carbon dioxide m(CO3) mO + CO2 where m= metal Examples: Na2(CO3) Na2O + CO2 Ca(CO3) CaO + CO2 Remember, Ca(CO3) is used to make cement! C. Heating a metallic hydroxide: a compound made of a metal and a OH - ion Metal hydroxide metal oxide + water A metal hydroxide always splits into a metal oxide and water, no matter what the metal is. Prediction: Write the metal oxide and water m(OH) mO + H2O where m= metal Examples: Na(OH) Na2O + H2O Ca(OH)2 CaO + H2O Metal hydroxides are sometimes heated and used to clean industrial equipment, since they can dissolve fats and grease.
D. Heating an acid: a compound of a H + ion and an anion Acid nonmetallic oxide + water An acid always splits into a nonmetallic oxide and water. Prediction: Write the nonmetallic oxide and water Acid nO + H2O where n is a non metal Examples: heating of nitric acid HNO3 NO2 + H2O Strong acids are often used to clean iron and steel products, like cars, before they are sold. III. Single replacement Element + compound element + compound A + BC B + AC when A is a metal A + BC C + AB when A is a nonmetal An element and a compound produce a different element and a different compound. Not every element will be able to replace another one in a compound, as we will see later when we see the Activity series. For the moment we will assume that the single element will replace the one in a compound. It is important to notice that: a. A metal always replaces a metal b. A non-metal always replaces a non-metal, especially if both are halogens c. A metal can replace hydrogen in acids and water Prediction: Check the activity series to see if the single element can replace the one in the compound. If it can, exchange a metal by a metal and nonmetal by nonmetal, except when hydrogen is part of the compound (water or an acid). In this case replace the hydrogen by a metal. Examples: Al + CuCl2 Cu + AlCl3 A metal (Al) replaces a less reactive metal (cu) Cl 2 + NaI NaCl + I 2 A nonmetal (Cl) replaces a less reactive nonmetal (I) Zn + HNO 3 H 2 + Zn(NO 3 ) 2 A metal (Zn) replaces H in an acid Na + H 2 O Na (OH) + H 2 A metal (Na) replaces H in an water IV.
