An Introduction to Types of Chemical Reactions
The purpose of this Internet assignment is to provide you with an independent learning
opportunity to learn about the different types of chemical reactions. The website address for
this assignment is www.ric.edu/ptiskus/reactions. On the website you will find a brief
description of the main types of chemical reactions. There are several representative
reactions listed for each main type. For these representative reactions there are links to either
videos or picture images of the reaction. Your task is to explore the different types of reactions
and answer the accompanying questions to a specific reaction or the main reaction type.
For all of the reactions listed you are required to convert the written description of the
reaction into a word equation and then a balanced chemical equation.
Note: Access to some of the websites may not be possible dependent upon your computer
system and or the network connection. You are still required to work through each main type
of reaction providing balanced chemical equations based on the word descriptions.
I.
How can I tell if a chemical reaction is occurring or has occurred? What are the
indicators of a chemical change?
Take a look at the image of a penny (zinc and copper metal) in nitric acid (HNO 3). The nitric
acid is a clear, colorless liquid. Write down your observations proving that a chemical change
is taking place in this mixture.
II.
Synthesis Reactions (Combination Reactions)
For each of the reactions listed in this section write down the word equation and then
balanced chemical equation.
aluminum and bromine
sodium and chlorine
water and potassium

II.
Synthesis Reactions (Combination Reactions)
List the types of evidence that a chemical reaction was taking place between the bromine and
aluminum.
Why does the reaction between bromine and aluminum stop?
How does the aluminum bromide precipitate become deposited on the watch glass covering
the beaker since it does not come in contact with the bromine liquid?
Draw the Lewis dot diagram for water and potassium before the potassium is added to the
water (label as prior to reaction). Draw the Lewis dot diagram for individual ions that binary
ionic compound potassium hydroxide. Label the cation and the anion for this compound.
III.
Single-Replacement Reactions
For each of the reactions listed in this section write down the word equation and then
balanced chemical equation.
aluminum and iron (III) oxide
copper (II) oxide and carbon
silver nitrate and copper

tin (II) chloride and zinc
List the types of evidence that a chemical reaction was taking place between the silver nitrate
and copper.
In the iron (III) Oxide and aluminum reaction the chemist illustrates the proper way to handle
hot glassware or in this case the reaction crucible. What is the person doing to illustrate this
method of safety?
What physical property of matter is being used to confirm a chemical change has occurred in
the iron (III) oxide and aluminum reaction?
In the copper (II) oxide and carbon reaction the gas being evolved from the reaction is being
captured and undergoes another chemical change. Write the reaction for this.
IV.
Double-Replacement Reactions
For each of the reactions listed in this section write down the word equation and then
balanced chemical equation.
calcium carbonate and sulfurous acid
lead (II) nitrate and potassium iodide
sodium chloride and silver nitrate

What would be the atmospheric reaction that would produce sulfurous acid?
V.
Decomposition Reactions
For each of the reactions listed in this section write down the word equation and then
balanced chemical equation.
water into hydrogen and oxygen
nitrogen triiodide
What is the evidence of a chemical reaction taking place in the decomposition of water?
How are decomposition reactions different from the other main reaction types?
