Transcript of Classifying Chemical Reactions

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
