The type of reaction that takes place when one element reacts with a compound to form a new compound and a different element is a ____
a. combination reaction.
b. decomposition reaction.
c. single-replacement reaction.
d. double-replacement reaction.

Respuesta :

C. single replacement. A single replacement is represented by this formula : AB + C = AC + B

Answer: c. single-replacement reaction.

Explanation:

Combination is a chemical reaction in which two or more than two substances combine to form a single product.

[tex]A+B\rightarrow AB[/tex]

Decomposition is a chemical reaction in which one substance decompose to form two or more than two products.

[tex]AB\rightarrow A+B[/tex]

A single replacement  is a chemical reaction in which a more reactive element displaces a less reactive element from its salt solution, thus one element reacts with a compound to form a new compound and a different element.

[tex]A+BC\rightarrow B+AC[/tex]

Double displacement is a chemical reaction in which ion exchange takes place.

[tex]AB+CD\rightarrow AD+BC[/tex]
