Sure! Let's go through each reaction step-by-step and write the balanced equations.
A) Iron metal and chlorine gas react to form solid iron(III) chloride.
To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides.
Iron (Fe) is a metal with a charge of 0, while chlorine (Cl) is a diatomic molecule with a charge of 0.
The reaction can be written as:
2 Fe(s) + 3 Cl2(g) → 2 FeCl3(s)
B) Solid aluminum carbonate decomposes to form solid aluminum oxide and carbon dioxide gas.
First, let's write the formula for aluminum carbonate: Al2(CO3)3.
The decomposition reaction can be written as:
Al2(CO3)3(s) → Al2O3(s) + 3 CO2(g)
C) Solid magnesium reacts with aqueous silver nitrate to form solid silver and aqueous magnesium nitrate.
First, let's write the formulas for magnesium (Mg) and silver nitrate (AgNO3).
The reaction can be written as:
Mg(s) + 2 AgNO3(aq) → 2 Ag(s) + Mg(NO3)2(aq)
