Answer 2

Reaction a) H2SO4 + NaOH => ?

The reaction between sulfuric acid (H2SO4) and sodium hydroxide (NaOH) is a classic example of an acid-base neutralization reaction. When these two substances react, they form water (H2O) and a salt called sodium sulfate (Na2SO4).

The balanced chemical equation for this reaction is:

H2SO4 + 2NaOH => 2H2O + Na2SO4 In this equation, two moles of sodium hydroxide react with one mole of sulfuric acid to produce two moles of water and one mole of sodium sulfate.

Reaction b) H2SO4 + Fe2O3 => ?

The reaction between sulfuric acid (H2SO4) and iron(III) oxide (Fe2O3) is an example of an acid-base reaction. However, in this case, iron(III) oxide is not a base but rather an amphoteric substance, meaning it can act as both an acid and a base.

The balanced chemical equation for this reaction depends on the conditions and the stoichiometry of the reactants. Without further information, it is difficult to determine the exact products of this reaction.

Reaction c) H2SO4 + SO2 => ?

The reaction between sulfuric acid (H2SO4) and sulfur dioxide (SO2) does not result in a simple acid-base neutralization reaction. Instead, it leads to the formation of various sulfur compounds, including sulfurous acid (H2SO3) and sulfur trioxide (SO3).

The balanced chemical equation for this reaction is:

H2SO4 + SO2 => H2SO3 + SO3 In this equation, sulfuric acid reacts with sulfur dioxide to produce sulfurous acid and sulfur trioxide.

Reaction d) H2SO4 + Zn(OH)2 => ?

The reaction between sulfuric acid (H2SO4) and zinc hydroxide (Zn(OH)2) is an acid-base neutralization reaction. When these two substances react, they form water (H2O) and a salt called zinc sulfate (ZnSO4).

The balanced chemical equation for this reaction is:

H2SO4 + Zn(OH)2 => ZnSO4 + 2H2O In this equation, one mole of sulfuric acid reacts with one mole of zinc hydroxide to produce one mole of zinc sulfate and two moles of water.

Reaction e) H2SO4 + KCl => ?

The reaction between sulfuric acid (H2SO4) and potassium chloride (KCl) is an acid-base neutralization reaction. When these two substances react, they form water (H2O) and a salt called potassium sulfate (K2SO4).

The balanced chemical equation for this reaction is:

H2SO4 + 2KCl => K2SO4 + 2HCl In this equation, one mole of sulfuric acid reacts with two moles of potassium chloride to produce one mole of potassium sulfate and two moles of hydrochloric acid.

Please note that the reactions mentioned above are simplified representations, and the actual reaction conditions and stoichiometry may vary depending on the specific experimental setup.
