Answer 1

H2SO4 + Ba = BaSO4 + H2
2H⁺ + SO₄²⁻ +Ba°=Ba²⁺ + SO₄²⁻ + H₂°
2H⁺  +Ba°=Ba²⁺ +  H₂°

Answer 2

Chemical Reaction: H2SO4 + Ba = BaSO4 + H2

The chemical equation provided represents the reaction between sulfuric acid (H2SO4) and barium (Ba) to form barium sulfate (BaSO4) and hydrogen gas (H2).

Balanced Chemical Equation: The balanced chemical equation for the reaction is: ``` H2SO4 + Ba -> BaSO4 + H2 ``` This equation indicates that one molecule of sulfuric acid reacts with one atom of barium to produce one molecule of barium sulfate and one molecule of hydrogen gas.

Reaction Description: In this reaction, sulfuric acid (H2SO4) reacts with barium (Ba) to produce barium sulfate (BaSO4) and hydrogen gas (H2). This is a precipitation reaction, where a solid (barium sulfate) is formed as a product.

Chemical Properties: - Sulfuric acid (H2SO4) is a strong mineral acid with the chemical formula H2SO4. It is colorless, odorless, and highly corrosive. - Barium (Ba) is a chemical element with the symbol Ba and atomic number 56. It is a soft, silvery alkaline earth metal. - Barium sulfate (BaSO4) is a white crystalline solid that is insoluble in water.

Safety Precautions: When handling sulfuric acid and barium, it is important to follow proper safety precautions due to their corrosive and potentially hazardous nature. Protective equipment and proper handling procedures should be used to ensure safety.

Application: Barium sulfate is commonly used as a contrast medium in medical imaging procedures such as X-rays and CT scans to enhance the visibility of certain tissues and organs.

Conclusion: The reaction between sulfuric acid and barium results in the formation of barium sulfate and hydrogen gas, representing a precipitation reaction. It is important to handle the reactants and products with care due to their chemical properties.
