Chemical EquationsUse word problems to write

and balance chemical equations, predict products, and determine precipitation

Diatomic Elements• There are 7 elements who always exists in

pairs, when they are not bonded to a different element. You must MEMORIZE these 7 diatomic elements:

H2, N2, O2, F2, Cl2, Br2, I2

• Think BrINClHOF or think H2 plus #7

Burn steel wool• Write the correct chemical equation, and

then balance it, for the following:• Iron plus oxygen yields iron (III) oxide

Burn magnesium ribbon• Write the correct chemical equation, and then

balance it, for the following:Magnesium plus oxygen yields magnesium oxide

Acid plus copperUse the activity series on your EOC reference

materials, write a single replacement equation for the reaction between hydrochloric acid and copper :

Acid plus zincUse the activity series on your EOC reference

materials, write a single replacement equation for the reaction between hydrochloric acid and zinc :

Synthesis rxn: Hydrogen plus oxygenWrite a synthesis reaction for the reaction

between hydrogen gas and oxygen gas to produce water:

Burn Baby Burn!Write the chemical reaction for the combustion

reaction between carbon tetrahydride and oxygen. Remember that combustion always produces carbon dioxide and water.

Iron (III) oxide plus TinWrite the chemical reaction for the single

replacement reaction between iron (III) oxide and tin. Use your activity series to help you.

Iron (III) oxide plus aluminumWrite the chemical reaction for the single

replacement reaction between iron (III) oxide and aluminum. Use your activity series.

Write the chemical reaction for the double replacement reaction between lead (II) nitrate and potassium iodide. Use your solubility rules on the EOC chart to predict who is the precipitate.

Write the chemical reaction for the reaction between CaC2 and water to yield dicarbon dihydride and calcium hydroxide.

Now, write the chemical reaction for the combustion of dicarbon dihydride. Remember that combustion involves oxygen and yields carbon dioxide and dihydrogen monoxide.

Use your activity series to write the single replacement reaction for aluminum and copper (II) chloride.

Use your activity series to write the single replacement reaction for aluminum and calcium chloride.

Write the double replacement reaction for the reaction between calcium chloride and sodium carbonate. Use your solubility rules on the EOC chart to determine if any products are precipitates.

Write the balanced chemical equation for the combustion reaction of ethanol. Ethanol’s formula is C2H5OH .

Write the double replacement reaction for the reaction between calcium chloride and sodium phosphate. Use your solubility rules on the EOC chart to determine if any products are precipitates.

Write the double replacement reaction for the reaction between sodium hydroxide and iron (III) chloride. Use your solubility rules on the EOC chart to determine if any products are precipitates.
