What is a synthesis reaction? a reaction that occurs when two or more reactants combine into one product a reaction that occurs when one element within a compound is exchanged with another element
a reaction that occurs when a substance combines with molecular oxygen, releasing light and energy
a reaction that occurs when a single substance breaks apart and forms two or more new substances

A synthesis reaction is a reaction that occurs when two or more reactants combine into one product.

Explanation:

A reaction that occurs when two or more reactants combine into one product is called a synthesis reaction.

A reaction that occurs when one element within a compound is exchanged with another element is called a single replacement reaction.

A reaction that occurs when a substance combines with molecular oxygen, releasing light and energy is called combustion.

A reaction that occurs when a single substance breaks apart and forms two or more new substances is called decomposition.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
