Question

Write and balance equations for the following reactions.

A) Iron metal and Chlorine gas react to form solid iron(III) chloride.
B) Solid aluminum carbonate decomposes to form solid aluminum oxide and carbon dioxide gas.
C) Solid magnesium reacts with aqueous silver nitrate to form solid silver and aqueous magnesium nitrate.
a) Balance equation A.
b) Balance equation B.
c) Balance equation C.
d) List the reactants for equation B.

Answer 1

Balanced equations for each reaction are provided with correct coefficients to ensure the same number of atoms on both sides. The reactants for the decomposition of aluminum carbonate are identified as solid aluminum carbonate.

Step-by-step explanation:

To balance chemical equations, adjust the coefficients in front of the formulas to ensure the same number of each type of atom on both sides of the equation. Here are the balanced reactions:

1. Iron metal and Chlorine gas react to form solid iron(III) chloride:
   2 Fe(s) + 3 Cl₂(g) → 2 FeCl₃(s)
2. Solid aluminum carbonate decomposes to form solid aluminum oxide and carbon dioxide gas:
   Al₂(CO₃)₃(s) → Al₂O₃(s) + 3 CO₂(g)
3. Solid magnesium reacts with aqueous silver nitrate to form solid silver and aqueous magnesium nitrate:
   Mg(s) + 2 AgNO₃(aq) → 2 Ag(s) + Mg(NO₃)₂(aq)

The reactants for equation B are solid aluminum carbonate (Al₂(CO₃)₃).
