Write complete ionic and net ionic equations for the reaction between sulfuric acid (H2SO4) and calcium carbonate (CaCO3).
svetlana [45]

Answer:

Complete ionic equation:

2H²⁺(aq) + SO₄²⁻(aq) + CaCO₃(s)   →  H₂O(l) + CO₂(g) + Ca²⁺(aq) + SO₄²⁻(aq)

Net ionic equation:

2H²⁺(aq) + CaCO₃(s)   →  H₂O(l) + CO₂(g) + Ca²⁺(aq)

Explanation:

Chemical equation:

H₂SO₄(aq) + CaCO₃(s)   →  H₂O(l) + CO₂(g) + CaSO₄(aq)

Balanced chemical equation:

H₂SO₄(aq) + CaCO₃(s)   →  H₂O(l) + CO₂(g) + CaSO₄(aq)

Complete ionic equation:

2H²⁺(aq) + SO₄²⁻(aq) + CaCO₃(s)   →  H₂O(l) + CO₂(g) + Ca²⁺(aq) + SO₄²⁻(aq)

Net ionic equation:

2H²⁺(aq) + CaCO₃(s)   →  H₂O(l) + CO₂(g) + Ca²⁺(aq)

Mg(s) + 2 HCl (aq) _MGCL2 (Aq) + H2 (g) the total pressure of gas collected over water is 740.0 mmhg and the temperature is 21.5
Julli [10]

The pressure of hydrogen gas formed  is 720.8 mmHg.

<h3>What is Partial Pressure ?</h3>

The pressure exerted by a (specified) component in a mixture of gases.

We have to understand one thing that the Hydrogen, which is collected over water, will be mixed with water vapor.

This means that the total pressure of the mixture will have two components.

  • the partial pressure of Hydrogen
  • the vapor pressure of water at 21.5 C

The vapor pressure of water at that temperature is approximately

19.231 mmHg.

This means that

\rm P_{total} = P_{hydrogen}  + \; P_{water vapor}

740 = \rm P_{hydrogen} + 19.231

\rm P_{hydrogen} = 740-19.231

\rm P_{hydrogen} = 720.8 mmHg

Therefore the pressure of hydrogen gas formed  is 720.8 mmHg.
