Question

Match the reaction to the type that best describes it. A. 2Na2O 4Na + O2 Combination B. 3Mg + 2AlCl3 2Al + 3MgCl2 Single replacement C. NaCl + KBr NaBr + KCl Decomposition D. 2H2 + O2 2H2O Double replacement

Answer 1

Decomposition 2Na2O ---->  4Na + O2 - One element breaks into two 

Double replacement NaCl + KBr ----> NaBr + KCl - Two elements are replaced 

Single replacement 3Mg + 2AlCl3 ----> 2Al + 3MgCl2 - One Element is replace 

Combination  2H2 + O2 ----> 2H2O - Two elements join to form one 

Answer 2

What are the 4 types of reactions?

The main four types of reactions are direct combination, analysis reaction, single displacement, and double displacement.

What are all the types of reactions?

Basic chemical reactions can be grouped into categories based on the types of changes that are occurring during the reaction. There are five basic categories - synthesis, decomposition, combustion, single replacement, and double replacement.
