Read each question carefully and provide your best answer. This worksheet covers different types of chemical reactions.

1. Which type of reaction combines two or more reactants to form a single, more complex product?

a

Decomposition reaction

b

Synthesis reaction

c

Single displacement reaction

d

Double displacement reaction

2. The reaction 2H₂O → 2H₂ + O₂ is an example of a:

a

Synthesis reaction

b

Decomposition reaction

c

Combustion reaction

d

Single displacement reaction

1. In a single displacement reaction, a more reactive element displaces a less reactive element from its compound.

T

True

F

False

2. Combustion reactions always produce oxygen gas as a product.

T

True

F

False

1. A reaction where two ionic compounds exchange ions to form two new compounds is called a   reaction.

2. The rapid reaction between a substance with oxygen, producing heat and light, is known as a   reaction.

1. Describe the key difference between a single displacement reaction and a double displacement reaction.

Match each reaction type with its general form.

1. Synthesis

 

a. AB → A + B

2. Decomposition

 

b. A + BX → AX + B

3. Single Displacement

 

c. AX + BY → AY + BX

4. Double Displacement

 

d. A + B → AB
