Balancing Equations(2 minutes)

100

Balance the following reaction

HCl  +  NaOH  -->  H₂O  +  NaCl

1 HCl  +  1 NaOH  -->  1 H₂O  +  1 NaCl

already balanced!! (don't actually write the 1s)

200

Balance the following equation:

ZnS  +  AlP  -->  Zn₃P₂  +  Al₂S₃

3 ZnS  +  2 AlP  -->  1 Zn₃P₂  +  1 Al₂S₃

(don't actually write the 1s)

300

Balance this equation:

CH₄  + O₂  -->  CO₂  +  H₂O

CH₄  + 2 O₂  -->  CO₂  + 2 H₂O

400

Balance this chemical equation:

Types of Reactions(30 seconds)

100

Identify the type of reaction:

6K  + B₂O₃  -->  3K₂O  +  2B

Single Replacement

200

Identify the type of reaction:

2C₁₀H₂₂  +  31O₂  -->  20CO₂  +  22H₂O

Combustion

300

Identify the type of reaction:

N₂  +  H₂  -->   NH₃

synthesis

400

Identify the type of reaction:

3NH₄OH  +  H₃PO₄  -->  (NH₄)₃PO₄  +  3H₂O

Double Replacement

500

Identify the type of reaction

NH₄NO₃  -->  N₂O  +  H₂O

decomposition

Grab Bag

100

Will this reaction happen? Why?

Mg + Cu(NO₃)₂ --> 

YES

magnesium is more active than copper, so it will react in a single replacement reaction

200

Predict the products:

Li  +  H₂O  -->

Li  +  H₂O  -->  Li₂O  +  H₂

300

What will happen in this reaction:

Br₂ + NaCl -->

NOTHING

Br is less active than Cl, so it will not be able to replace it

400

Write a balanced equation when fluorine gas is bubbled through an aqueous solution of sodium bromide.

F₂ + 2NaBr --> 2NaF + Br₂
