Transcript Chemical Equations

Chemical Equations
Use 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 copper
Use the activity series on your EOC reference
materials, write a single replacement equation
for the reaction between hydrochloric acid and
copper :
Acid plus zinc
Use 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 oxygen
Write 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 Tin
Write 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 aluminum
Write 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.
