8.1 Practice Worksheet B
Part 1
Turning word equations into formula equations can be a bit tricky. Before you balance the equation, you must first write a correct ionic, covalent (possibly organic), or acid formula. In addition, you should also include the state of matter for each compound.
States of Matter in Chemical Equations
(s) – solid (l) – liquid (g) – gas (aq) - aqueous pure metals & metalloids; a few nonmetals
Ex:
Water, ammonia hydrocarbons larger than butane
Ex:
Diatomic gases
Ex:
Soluble ionic compounds
Ex: insoluble ionic compounds
Ex:
Most covalent compounds
All acids
Ex:
Ex:
 To check if an ionic compound is soluble (aq) you must use a solubility chart or solubility rules.
 Remember!!! o Insoluble ionic compounds: _______ able to be dissolved – use (s) o Soluble ionic compounds: able to be dissolved – use (aq)
Part 2
Write balanced formula equations for the following reactions, including the states of matter for each compound. (You may need to use old techniques like the criss-cross rule to identify an individual formula)
1.
zinc + lead (II) nitrate yield zinc nitrate + lead
2.
aluminum bromide + chlorine yield aluminum chloride + bromine
3.
potassium chlorate when heated yields potassium chloride + oxygen gas

4.
aluminum + hydrochloric acid yield aluminum chloride + hydrogen gas
5.
calcium hydroxide + phosphoric acid yield calcium phosphate + water
6.
copper + sulfuric acid yield copper (II) sulfate + water + sulfur dioxide
7.
hydrogen + nitrogen monoxide yield water + nitrogen
