- Finish the molecular equations below, balance them, and then write a corresponding net ionic equation. You
will need to use the solubility rules to determine whether any of the products will precipitate.
a. Na 2 CO 3 (aq)+ZnCl 2 (aq)→
b. NH 4 Cl(aq)+Pb(NO 3 ) 2 (aq)→
c. Al(s)+HI(aq)→
d. HCl(aq)+Ba(OH) 2 (aq)→
e. Zn(s)+Fe(NO 3 ) 3 (aq)→
f. Cl 2 (g)+KBr(aq)→ - Write a balanced net ionic equation from each of the word equations below.
a. Aqueous cobalt(III) chloride reacts with aqueous ammonium sulfate to produce aqueous ammonium
chloride and solid cobalt(III) sulfate.
b. Aluminum metal reacts with a solution of copper(II) acetate to produce aqueous aluminum acetate and
copper metal.
c. Nickel metal reacts with sulfuric acid (H 2 SO 4 ) to produce aqueous nickel(II) sulfate and hydrogen gas. - Write a balanced net ionic equation for each of the following situations. You will need to determine the
products first. - Aqueous solutions of potassium hydroxide and chromium(III) chloride are mixed.
- Magnesium metal is dipped into a solution of lead(II) nitrate.
- Solid iron(III) hydroxide is added to a solution of hydrochloric acid.
- Fluorine gas is bubbled into a solution of sodium iodide.

Points to Consider
Heat and energy are important concepts in chemistry, as most chemical reactions are accompanied by a transfer of
energy.
- What is heat, and how does a transfer of heat occur?
- How do different substances respond to an input or loss of heat?
