Question:

Write and balance the chemical reaction described in each of the following and then identify the type of reaction that occurred.

a. Iron metal reacts with oxygen gas in air to form solid iron(III) oxide.

b. Ammonium dichromate solid decomposes to form solid chromium(III) oxide, gaseous nitrogen, and gaseous water.

c. Solid sodium reacts with liquid water to form aqueous sodium hydroxide and hydrogen gas.

d. Aqueous sodium bicarbonate reacts with hydrobromic acid to form aqueous sodium bromide, carbon dioxide gas, and liquid water.

e. Aqueous lead(II) nitrate reacts with aqueous potassium iodide to form solid lead(II) iodide and aqueous potassium nitrate.

Balanced Chemical Equation:

In stoichiometry we have to balance the chemical equation prior to performing any calculation, such as finding chemical concentrations of the products (molarity, molality). Balancing consists of placing numbers that represent moles before each compound.
