Question

Identify the reaction type for each generic chemical equation. A + B → AB: AB → A + B: Hydrocarbon + O2 → CO2 + H2O: AB + CD → AD + CB:

Answer 1

Answer:

1. $A+B\rightarrow AB$: Synthesis

$AB\rightarrow A+B$: Decomposition

$Hydrocarbon+O_2\rightarrow CO_2+H_2O$:  Combustion

4. $AB+CD\rightarrow AD+CB$ : Double displacement

Explanation:

1. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

Example: $Li_2O+CO_2\rightarrow Li_2CO_3$  

2. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Example: $Li_2CO_3\rightarrow Li_2O+CO_2$

3. Combustion is a type of chemical reaction in which hydrocarbon is reacted with oxygen to form carbon dioxide and water.

Example:  

$CH_4+2O_2 \rightarrow CO_2+2H_2O$

4. Double displacement reaction is one in which exchange of ions take place.  

Example: $NaOH+HCl\rightarrow NaCl+NH_2O$

Answer 2

Answer:

Identify the reaction type for each generic chemical equation.

A + B → AB:  synthesis

AB → A + B:  decomposition

Hydrocarbon + O2 → CO2 + H2O:  combustion

AB + CD → AD + CB:   replacement
