November 12, 2013 Once you’re in, you’re in.When the bell rings, electronics and

headphones away working on the Do Now (half sheet you picked up).

You have until 5 minutes after the bell until this is collected.

Reaction Stoichiometry Test

• Reviewing more today

• 1 hour to finish tomorrow

• New content tomorrow after test

Have out

1. Guided Practice you picked up today

2. Reaction Stoichiometry flow sheet (raise hand if you can’t find it)

3. Blank sheet of paper for any misc. notes we need to take

4. Calculator if you have one; don’t ask to use mine – get one from the pink bucket.

5. Naming flow chart

Objective

• Utilize mole ratios from the balanced equation to calculate the quantity of one substance in a reaction given the quantity of the desired substance in the reaction (given moles or mass and ending with moles or mass)

Ca(OH)2

Fe2(SO4)3

PbO2

Na2CO3

K2Cr2O7

151g 74g

208g 239g

106g 294g

Fe2(SO4)3

PbO2

Na2CO3

K2Cr2O7

0.166 moles 0.338 moles

0.120 moles 0.105 moles

0.236 moles 0.085 moles

Part IVWrite equations for the following reactions:The combustion of propane (C3H8)

The reaction between copper sulfate and sodium

carbonate

The reaction between hydrochloric acid and

copper carbonate

C3H8 + O2 → CO2 + H2O

CuSO4 + Na2CO3 → Na2SO4 + CuCO3

HCl + CuCO3 → CuCl2 + H2O + CO2

Part VAdd state symbols to the following equationsThe combustion of propane (C3H8)

The reaction between copper sulfate and sodium

carbonate

The reaction between hydrochloric acid and

copper carbonate

C3H8 + O2 → CO2 + H2O

CuSO4 + Na2CO3 → Na2SO4 + CuCO3

HCl + CuCO3 → CuCl2 + H2O + CO2

Part VIBalance the equationsThe combustion of propane (C3H8)

The reaction between copper sulfate and sodium

carbonate

The reaction between hydrochloric acid and

copper carbonate

C3H8 + O2 → CO2 + H2O

CuSO4 + Na2CO3 → Na2SO4 + CuCO3

HCl + CuCO3 → CuCl2 + H2O + CO2

Part VIIIf 25g propane is burned, what mass of oxygen is required for complete combustion

C3H8 + O2 → CO2 + H2O

Part VIIIf 15g of copper carbonate is reacted with excess hydrochloric acid, calculate the mass of carbon dioxide formed. If 3.1g of carbon dioxide is formed, calculate the percent yield.HCl + CuCO3 → CuCl2 + H2O + CO2

Part VIIIf 20g copper sulfate is reacted with 20g sodium carbonate, which reactant is the limiting reactant and what mass of precipitate is formed?

CuSO4 + Na2CO3 → Na2SO4 + CuCO3

Ammonium hydrogen phosphate, (NH4)2HPO4, a common fertilizer, is made from reacting phosphoric acid, H3PO4, with ammonia, NH3.

a. Write the balanced equation for this reaction.

b. If 10.00 g of ammonia react, how many moles of fertilizer will be produced?

c. What mass of ammonia will react with 280 kg of H3PO4?
