Answer:
C2H5OH + Na = C2H5ONa + H2 - Single replacement reaction
AgCl + HNO3 = AgNO3 + HC - Double replacement reaction
N2 + H2 = NH3 - Combination reaction
MgCO3 = MgO + CO2 - Decomposition reaction
Explanation:
Single replacement reaction - The type of reaction in which one strong ion replaces the weak ion from the solution.
For example: C2H5OH + Na = C2H5ONa + H2
Double replacement reaction - The reaction in which two compounds in a solution reacts by interchanging their ions and forms a new product.
For example: AgCl + HNO3 = AgNO3 + HCl
Combination reaction - The type of reaction in which two or more compounds combine together to form a single compound.
For example: N2 + H2 = NH3
Decomposition reaction - The type of reaction in which only one compounds break down into two or more new compounds.
For example: MgCO3 = MgO + CO2
Hence, the correct answer is:
C2H5OH + Na = C2H5ONa + H2 - Single replacement reaction
AgCl + HNO3 = AgNO3 + HC - Double replacement reaction
N2 + H2 = NH3 - Combination reaction
MgCO3 = MgO + CO2 - Decomposition reaction
