RXN types
What rxn type is this? Is it balanced? If not, balance it!
Cu + Cl2 --> CuCl2
Synthesis. Yes! Cu + Cl2 --> CuCl2
What rxn type is this? What would be produced by this rxn?
K2SO4 --> ? + ?
Decomposition
K2SO4 --> 2 K + SO4
Balance the following equation and add states of matter: _____H2 + ____O2 ---> ____H2O
2 H2 (g) + 1 O2 (g) ---> 2 H2O (l)
The Law of Conservation of Mass states that _________ .
Matter cannot be created or destroyed
What type of reaction can result in the formation of a precipitant?
Double replacement
What rxn type is this? Is it neutralized and balanced? If not, neutralize and balance it!
MgCl --> Mg + Cl
Decomposition. No. MgCl2 --> Mg + Cl2
What reaction type is this? What would be produced by this rxn?
Na + Cl --> ?
Synthesis
Na + Cl --> NaCl
Balance the following Equation: _____KClO3 ---> KCl + ______O2
2KClO3 ---> 2KCl + 3O2
T/F is this naming for Fe2O3 correct? Why or why not? Rename if needed. Di-ironide trioxygen
No prefixes for ionic, suffix on wrong element. Correct: Iron (II) oxide
What does it mean for a metal to be more reactive than another?
teacher's discretion but should be along the lines of
- is easily displaced by the more reactive metal, dissolves
- more reactive cation becomes more stable by displacing the other --> more reactive cation steals electrons from anion to become more stable than the less reactive cation
What rxn type is this? Is it balanced? If not balance it! Name the bolded compounds.
CuCl2 + Zn --> ZnCl2 + Cu
Type: Single Replacement.
Balance: Yes!
Naming: Copper (II) chloride and Zinc chloride
What rxn type is this? What would this rxn produce?
CH4 + O2 --> ? + ?
Combustion
CH4 + 2 O2 --> CO2 + 2 H2O
Balance the following equation: P + O2 --> P2O5
4P + 5O2 ---> 2P2O5
What type of compound is this: CaCl2
ionic
Think of what we learned in the single replacement lab, would this reaction occur? Why or why not?
MgSO4 (aq) + Cu (s) --> CuSO4 (aq) + Mg (s)
No, copper is less reactive than magnesium so it wouldn't displace it.
What rxn type is this? Write out the reaction formula. Neutralize and balance.
Aluminum iodide + Barium oxide --> Aluminum oxide + Barium iodide
Double replacement
2 AlI3 + 3 BaO --> Al2O3 + 3 BaI2
What rxn type is this? Predict the products.
Cobalt (III) thiosulfate + Lead (II) bromide --> ? + ?
Double replacement
Cobalt (III) bromide + Lead (II) thiosulfate
Also accepting: CoBr3 + PbS2O3
Balance the following equation and add states of matter: ____C3H8 + _____O2 ---> ____CO2 + ____H2O
1C3H8 (g) + 5O2 (g) ---> 3CO2 (g) + 4H2O (g)
Model a solid metal in a liquid.
teacher's discretion
If Principal Shoemaker wanted to recover pure silver from a solution of silver nitrate, which metal should she use to recover the most pure silver: mercury, zinc, or calcium? Why? Explain using a balanced chemical equation with states of matter.
AgNO3 (aq) + Ca (s) --> CaNO3 (aq) + Ag (s)
Calcium is the most reactive, would most readily displace the silver to become more stable.
What rxn type is this? Balance it!
CH3 + O2 --> CO2 + H2O
Combustion
4 CH3 + 5 O2 --> 4 CO2 + 6 H2O
What reaction type is this? Predict the products. Using your knowledge of reactivity would this reaction occur? Why or why not?
MgCO3 (aq) + Ca (s) -->
Single replacement
CaCO3 (aq) + Mg (s)
Yes, Ca is more reactive than Mg so Ca would displace the Mg to form a more stable product
Balance the following equation and add states of matter: ___NaBr + ____CaF2 ---> ____NaF + ____CaBr2
2NaBr (aq) + 1CaF2 (s) ---> 2NaF (aq) + 1CaBr2 (aq)
Name this compound: CrN
Chromium (III) Nitride
If Spongebob wanted to precipitate aluminum as a ionic compound, which of these solutions should they react the aluminum chloride with? Write a balanced equation with states of matter and explain why it would work.
KOH or MgSO4 or CaNO3
AlCl3 (aq) + KOH (aq) --> AlOH3 (s) + KCl (aq)
used solubility table, OH and PO4 w Al is insoluble.
