Chemical Reaction Types - help9
There are three questions in this Question Group. The three questions are very similar. Only the ordering of answer options differs from one question to the next.
Version 1:
Identify the reaction type of each reaction described below.
To be successful with this question, you need to understand the basics of each reaction type. Once understood, you will be able to classify each of the three reactions according to its type. The infographic below describes each of the five reaction types. Study it carefully and then answer the question. You should notice that the process gets easier as you do more questions.
