Double replacement
Synthesis
Decomposition

Answer 1

In a synthesis reaction, sodium metal combines with chlorine gas to form sodium chloride. The reaction of water breaking down into hydrogen and oxygen gases is an example of decomposition. Glucose reacting with oxygen to create water, carbon dioxide, and energy is a combustion reaction.

Step-by-step explanation:

Synthesis:

The reaction of sodium metal (Na) with chlorine gas (Cl2) to form sodium chloride (NaCl) is an example of a synthesis reaction.

Decomposition:

The reaction of water (H2O) breaking down into hydrogen gas (H2) and oxygen gas (O2) is an example of a decomposition reaction.

Combustion:

The reaction of glucose (C6H12O6) with oxygen gas (O2) to produce water (H2O), carbon dioxide (CO2), and energy is an example of a combustion reaction.

Single replacement:

The reaction of aluminum hydroxide (Al(OH)3) with lithium (Li) to form lithium hydroxide (LiOH) and aluminum (Al) is an example of a single replacement reaction.

Double replacement:

The reaction of hydrochloric acid (HCl) with sodium hydroxide (NaOH) to form sodium chloride (NaCl) and water (H2O) is an example of a double replacement reaction.
