ANSWER

The reaction above is classified as a double replacement reaction.

The reaction is classified as a combustion reaction.

The reaction is classified as a decomposition reaction.

The reaction is classified as a single replacement reaction.

The reaction is classified as a combination reaction.

Step-by-step explanation

The reaction above is classified as a double replacement reaction.

A double replacement reaction is a type of chemical reaction that occurs when two reactants exchange cations or anions to yield two new products. The exchanged cations in the reaction are K⁺ and Pb²⁺. Double replacement reactions are also called double displacement reactions.

The reaction is classified as a combustion reaction.

A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.

The reaction is classified as a decomposition reaction.

A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.

The reaction is classified as a single replacement reaction.

A single replacement reaction, also called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound. The starting materials are always pure elements, such as a pure Lithium metal used in the given equation or hydrogen gas, plus an aqueous compound.

The reaction is classified as a combination reaction.

Combination reactions occur when two or more substances combine to form a new substance. · Combination reactions can also be called synthesis.
