Predict the products and then write the complete balanced chemical equation with states of matter:
1. Sulfuric Acid and sodium hydroxide
2. Aluminum and copper (II) sulfate
3. Silver nitrate and iron (III) chloride
4. Magnesium heated
5. Aluminum oxide
1. The reaction between sulfuric acid (H2SO4) and sodium hydroxide (NaOH) is a neutralization reaction. The products are water (H2O) and sodium sulfate (Na2SO4).
To balance the equation, we need the same number of each type of atom on both sides.
H2SO4 + 2NaOH -> 2H2O + Na2SO4
2. The reaction between aluminum (Al) and copper (II) sulfate (CuSO4) is a single replacement reaction. The aluminum will replace the copper in the sulfate compound to form aluminum sulfate (Al2(SO4)3), while copper will become a solid element.
To balance the equation, we need the same number of each type of atom on both sides.
2Al + 3CuSO4 -> Al2(SO4)3 + 3Cu
3. The reaction between silver nitrate (AgNO3) and iron (III) chloride (FeCl3) is a double replacement reaction. The silver and iron will swap partners, forming silver chloride (AgCl) and iron nitrate (Fe(NO3)3).
To balance the equation, we need the same number of each type of atom on both sides.
3AgNO3 + FeCl3 -> 3AgCl + Fe(NO3)3
4. When magnesium (Mg) is heated, it undergoes a decomposition reaction, breaking down into its elemental form.
To represent this reaction, we simply write:
Mg -> Mg
5. Aluminum oxide (Al2O3) is already a compound and does not undergo a chemical reaction when written on its own.
So, the balanced equation is:
Al2O3 -> Al2O3
