Question

Write a balanced equation for the reaction of H2SO4 with 1) Zn 2) CaCO3 3) NaOH

Answer 1

Answer and Explanation:

$\diamond$ Chemical reactions are processes in which one or more substances (reactants) react or combine together to form one or more substances (products)

$\diamond$ A general chemical reaction can be given as :

$\huge \text{\boxed{\mathcal{REACTANTS \rightarrow PRODUCTS}}}$

$\diamond$ Sulphuric acid (H₂SO₄) reacts with zinc (Zn) to produce zinc sulphate (ZnSO₄) and hydrogen gas (H₂)

$\boxed{H_2SO_4 + Zn \rightarrow ZnSO_4 + H_2}$

$\diamond$ Sulphuric acid (H₂SO₄) reacts with calcium carbonate (CaCO₃) to produce calcium sulphate (CaSO₄), water (H₂O) and carbon dioxide (CO₂)

$\boxed{H_2SO_4 + CaCO_3 \rightarrow CaSO_4 + H_2O + CO_2}$

$\diamond$ Sulphuric acid (H₂SO₄) reacts with sodium hydroxide (NaOH) to produce sodium sulphate (Na₂SO₄) and water (H₂O)

$\boxed{H_2SO_4 + 2NaOH \rightarrow Na_2SO_4 + 2H_2O}$
