Answer 2

Characteristics of Sulfuric Acid Reaction with Various Substances

Sulfuric acid (H2SO4) is a strong acid known for its corrosive and reactive properties. Let's explore its reactions with the given substances:

1) Cu(NO3)2 and Cu: - Sulfuric acid reacts with copper nitrate (Cu(NO3)2) to produce copper sulfate, nitrogen dioxide, and water. [[1]]

2) N2O5 and N2: - Sulfuric acid reacts with dinitrogen pentoxide (N2O5) to form nitric acid (HNO3) and nitrogen dioxide gas (NO2). [[2]]

3) O2 and HNO3: - Sulfuric acid does not directly react with oxygen (O2) to produce nitric acid (HNO3). However, nitric acid can be produced through a multi-step process involving sulfuric acid and various nitrogen oxides. [[3]]

4) Mg(OH)2 and MgO: - Sulfuric acid reacts with magnesium hydroxide (Mg(OH)2) to form magnesium sulfate and water. It does not directly react with magnesium oxide (MgO). [[4]]

In summary, sulfuric acid exhibits distinct reactions with each of the given substances, leading to the formation of various products.
