Question

Classify the chemical reaction shown here: Mg + H2SO4 → MgSO4 + H2

Answer 1

The chemical reaction for Magnesium (Mg) in Sulfuric acid (H2SO4) is given by the equation:

Mg + H2SO4 ---> MgSO4 + H2 gas.

The products of this reaction are Magnesium Sulfate (MgSO4, a salt) and elemental Hydrogen (H2, a gas), as shown in the equation.

Answer 2

Answer:

Single Displacement Reaction

Explanation:

Chemical reactions are broadly classified as:

1) Synthesis which involves combination of 2 or more reactants to form a single product

2) Decomposition which involves the breakdown of a complex reactant into two or more simpler products

3) Single displacement reaction which involves displacement of a more reactive element from a less reactive element in a compound

4) Double displacement involves exchange of ions between 2 salts

The given reaction is:

Mg + H2SO4 → MgSO4 + H2

Here Mg is more reactive and displaces H from H2SO4 forming MgSO4. This is an example of a single displacement reaction
