Chemical Equations ONLINE PROJECT
Complete each section of the project by answering the questions in complete sentences on report sheet provided at
end of the instructions. Websites and videos are provided to assist you. Equations should be rewritten with correct
balancing. Typed or copied work will not be accepted. Neatness counts. I will only accept projects
completed on the report sheet that are handwritten and turned in by the beginning
of class on December 11th.

1. What does the Law of Conservation of Mass state?
2. What is a reversible reaction and how is it indicated?
3. Write the reaction for a silver spoon tarnishing. What type of reaction is this?
4. Write the reaction for the burning of Methane gas (the gas used in Chemistry lab). What
type of reaction is this?
5. Write the reaction of the neutralization of stomach acid. What type of reaction is this?
6. Does the order in which the reactants and products are written in the chemical equation
matter?
7. Very often you will see the descriptions of the materials in the reaction in parentheses
after the material. List the different things that can be written.
8. What hint do they give you when balancing equations with polyatomic ions?
9. What about with water?
10. Use the website to help you balance the following equations. It takes you through each
one, step by step.
a. _ N2 + _ H2
_ NH3
b. AgNO3 + _ CaCl2
_ AgCl + _ Ca (NO3)2
c. _ H2SO4 + _ K+(OH)-
_ K+2(SO4)2+ + _ H2O
d. _ H3PO4 + _ Ca2+(OH)-2
e. _ CH4 + _ O2
_ H2O + _ CO2
f. _ C4H10 + _ O2
g. _ C3H7OH + _ O2
h. _ Fe3O4 + _ CO
_ H+(OH)- + _ Ca2+3(PO4)3-2
_ CO2 + _ H2O
_ CO2 + _ H2O
_ CO2 + _ Fe

11. Write the Balanced Equation from these word equations. Tell what type of reaction is
occurring. Use the website to check your answers.
a. sulfur trioxide and water combine to make sulfuric acid.
b. calcium carbonate will come apart when you heat it to leave calcium oxide and
carbon dioxide.
c. aluminum hydroxide and sulfuric acid (H2SO4) neutralize to make water and
aluminum sulfate.
d. propane burns (C3H8) with oxygen to produce carbon dioxide and water.
e. zinc and copper II sulfate yield zinc sulfate and copper metal

1. Formulas show chemistry at a
. Equations show chemistry
2. What are two important principles to remember when balancing equations?
3. What are the diatomic molecules?
4. What does a delta sign mean above the arrow?
5. Read how to predict the products for each of the different types of reactions. Use the
website to practice predicting the products by clicking on the hyperlink after each section.
Complete at least 3 of these and copy them onto your report page.
Website 3: http://misterguch.brinkster.net/6typesofchemicalrxn.html
1. Give the general form for each of the six types of chemical reactions:
a. Combustion
b. Synthesis
c. Decomposition
d. Single displacement
e. Double displacement
f. Acid-base (we will talk about this in the acid/base Unit – it is a type of double
displacement)

2. Use Mr. Guch's Handy Checklist for figuring out what type of reaction is taking
place. Then answer “How do you know the following reaction is occurring?” (the first
one is done for you as an example)
a. Combustion – oxygen is one of the reactants and the products are carbon dioxide
and water.
b. Synthesis
c. Decomposition
d. Single displacement
e. Double displacement
f. Acid-base (we will talk about this in the acid/base Unit)
3. List what type the following reactions are. Use the website to check your answers.
1) NaOH + KNO3 --> NaNO3 + KOH
2) CH4 + 2 O2 --> CO2 + 2 H2O
3) 2 Fe + 6 NaBr --> 2 FeBr3 + 6 Na
4) CaSO4 + Mg(OH)2 --> Ca(OH)2 + MgSO4
5) NH4OH + HBr --> H2O + NH4Br
6) Pb + O2 --> PbO2
7) Na2CO3 --> Na2O + CO2
