Answer 3

Types of Reactions

1. CaO + 2HCl = CaCl2 + H2O - This is a neutralization reaction between an acid (HCl) and a base (CaO), resulting in the formation of a salt (CaCl2) and water (H2O) [[1]].

2. 2Na + I2 = 2NaI - This is a combination reaction where two elements (sodium and iodine) combine to form a compound (sodium iodide) [[2]].

3. Zn + CuSO4 = Cu + ZnSO4 - This is a single displacement reaction where zinc (Zn) displaces copper (Cu) from copper sulfate (CuSO4), resulting in the formation of copper and zinc sulfate [[3]].

4. 2Ba + O2 = 2BaO - This is a combination reaction where barium (Ba) reacts with oxygen (O2) to form barium oxide (BaO) [[4]].

5. 3Mg + N2 = Mg3N2 - This is a combination reaction where magnesium (Mg) reacts with nitrogen (N2) to form magnesium nitride (Mg3N2) [[5]].

6. 2AgNO3 = 2Ag + 2NO2 + O2 - This is a decomposition reaction where silver nitrate (AgNO3) decomposes into silver (Ag), nitrogen dioxide (NO2), and oxygen (O2) [[6]].

7. 2AgF + Na2S = Ag2S + 2NaF - This is a double displacement reaction where silver fluoride (AgF) reacts with sodium sulfide (Na2S) to form silver sulfide (Ag2S) and sodium fluoride (NaF) [[7]].

8. 2HgO = 2Hg + O2 - This is a decomposition reaction where mercury(II) oxide (HgO) decomposes into mercury (Hg) and oxygen (O2) [[8]].

9. 6MnO + O2 = 2Mn3O4 - This is a combination reaction where manganese(II) oxide (MnO) reacts with oxygen (O2) to form manganese(III) oxide (Mn3O4) [[9]].

10. 2Cu + O2 = 2CuO - This is a combination reaction where copper (Cu) reacts with oxygen (O2) to form copper(II) oxide (CuO) [[10]].
