Write the balanced equation for the reaction between sucrose(C12H22O11) and oxygen(O2) that yields gaseous carbon dioxide and liquid water.
Classify Chemical Reactions
Identify Each type of Chemical Reaction
4 Types of Chemical Reactions
1.Synthesis2.Combustion3.Decomposition4.Replacement
2 or more substances combine to form a single compound.
2Na + Cl2 ----> 2NaCl
General: A + B AB
+
Which reaction is a synthesis reaction? 1. Fe + 2HCl --> FeCl2 + H2
2. 2Mg + O2 --> 2MgO
3. 2H2O2 --> 2H2O + O2
4. NaOH + HCl --> NaCl + H2O
A single compound breaks down to form two or more simpler substances
H2CO3 -----------------> H2O + CO2
General: AB A + B
Which reaction is a decomposition reaction?
1. Fe + 2HCl --> FeCl2 + H2
2. 2Mg + O2 --> 2MgO
3. 2H2O2 --> 2H2O + O2
4. NaOH + HCl --> NaCl + H2O
One element takes the place of another element.
Zn + 2HCl -----> ZnCl2 +H2
General: AB + C AC + B
+ +
Zinc replaced hydrogen
2 elements switch places to form new compounds.
NaCl + AgNO3 ----> NaNO3 + AgCl
General: AB + CD AD + CB
+ +
Chlorine and nitrate switch places
Which Reaction is Single …..….Double Replacement?
1. Fe + 2HCl --> FeCl2 + H2
2. 2Mg + O2 --> 2MgO
3. 2H2O2 --> 2H2O + O2
4. NaOH + HCl --> NaCl + H2O
Oxygen combines with a substance and releases energy (heat and/or light)
Examples: coal burning power plants fire
gas turbines and jet engines guns and explosivesPiston engines (cars)
C(s) + O2 (g) CO2 (g)
General: A + O2 AO

Balance the following Reactions:Zn + HCl ZnCl2 + H2
What type of reaction is this?NaCl + AgF --> NaF
+ AgCl
