Question

Select 2 that apply.

A synthesis reaction will be:

a reaction in which one element displaces a similar element in a compound

a chemical reaction in which two or more substances combine to form a new compound

AB→A + B

a reaction in which a single compound undergoes a chemical reaction to produce two or simpler substances

A + B → AB

Answer 1

A chemical reaction in which two or more substances combine to form a new compound.

2. A + B → AB.

Step-by-step explanation:

1. Synthesis reaction: A synthesis reaction, also known as a combination reaction, is a chemical reaction in which two or more substances combine to form a new compound. This type of reaction is characterized by the formation of chemical bonds between the reactants to create a single product.

2. A + B → AB: This equation represents a synthesis reaction. In this reaction, two separate elements or compounds (represented by A and B) combine to form a new compound (represented by AB). The arrow in the equation indicates the direction of the reaction, with the reactants on the left side and the product on the right side.

The other options, such as "a reaction in which one element displaces a similar element in a compound" and "a reaction in which a single compound undergoes a chemical reaction to produce two or simpler substances," do not accurately describe a synthesis reaction. Instead, these options correspond to other types of chemical reactions, namely displacement reactions and decomposition reactions, respectively.
