What do all acids produce in solution?

H+ (hydrogen ions)

100

What are the products of neutralization reactions?

Ionic salt and water

200

Chemical formula for Barium Iodide

BaI2


Remember the Criss-Cross Method!

200

Identify the type of reaction:


H2O2 --> H2  + O2

Decomposition

200

Is the following chemical equation balanced?


Zn + 2HCl → H2 + ZnCl2

Yes it is balanced - the number of atoms of each type of element are the same on both reactant and product side. (i.e there are 2 H atoms on each side)

200

What ions are present when bases are dissolved in water? 

OH- (hydroxide ions) or CO32- (carbonate ions)

200

How does the pH of an acidic solution change when a base is pipetted into the acidic solution?

The pH will increase (move closer to neutral)

NCl3

300

Identify the type of reaction:

2 C6H14 (l) + 19 O2 (g) --> 12 CO2 (g) + 14 H2O (g)

Combustion (Complete combustion)

300

Balance the following equation:


____ Na +____ H2O → ____ NaOH +____ H2



2 Na + 2 H2O → 2 NaOH + H2

Chemical forumla for Iron (III) sulfate

Fe2(SO4)3

400

Identify the true statement:

1. Single displacement reactions produce precipitates

2. Synthesis reactions produce a lot of energy

3. Double displacement reactions involve an element reacting with a compound.


The true statement:


2. Synthesis reactions produce a lot of energy

400

Balance the following Equation:


____CaCO3 + ____ HCl → ____ CaCl2 + ____ H2CO3



CaCO3 + 2  HCl → CaCl2 + H2CO3

400

Identify the true statement:

1. Acids turn red litmus blue and blue litmus red.

2. Household cleaners are acidic

3. Acids and bases conduct electricity

4. Acids and bases both react with metals

The only true statement:


3. Acids and bases conduct electricity (because they produce ions!)

What is the purpose of an indicator?

To determine if a solution is basic or acidic (also to indicate when you are close to reaching neutralization)

500

Chemical formula for ammonium chlorate 

NH4ClO3

500

Predict the products:


Ba(OH)2  +  Al(NO3)3 --> ____?____ + ____?____

This is a double displacement reaction:


3 Ba(OH)2  + 2 Al(NO3)3 --> 3 Ba(NO3)2 + 2 Al(OH)3

500

Balance the following chemical equation:


__ C5H12 + __ O2   --> __ CO2  + __ H2



 C5H12 + 8 O2   --> 5 CO2  + 6 H2O

How much more acidic is stomach acid at pH2 than black coffee at pH 5?

a) 1000 times more acidic

b) 30 times more acidic

c) 1000 times more basic

d) 3000 times more acidic

pH2 vs. pH 5 is a difference of 3.

This means there are THREE 10-fold differences

10 x 10 x 10 

= 1000 times more acidic

Determine the products of the neutralization reaction (and BALANCE!):

KOH + H2SO4  --> ________  +  _________


Remember, neutralization is just a fancy double displacement reaction!


2KOH + H2SO4  -->  K2SO4  +  2H2O
