Balancing Reactions
Balance the equation AgNO3 + NaCl --> AgCl + NaNO3
1,1,1,1
Type of reaction? Predict products? Balance?
CaCO3 --> ??
What is decomposition (of a carbonate)?
CaO + CO2
something that causes atoms to move quicker and thus speeds up a chemical reaction
What is temperature/heat?
Type of reaction? Balance?
CaCO3 --> CaO + CO2
Decomposition (carbonate)
CaCO3 --> CaO + CO2
Balance the equation: KCl --> K + Cl2
2,2,1
Type of reaction? Predict products? Balance?
C4H10 + O2 -->
2 C4H10 + 13 O2 --> 8 CO2 + 10 H2O
A substance that increases the speed of a reaction by lowering the activation energy without being used up in the reaction.
What is a catalyst?
Type of reaction? Balance?
NaClO3 --> NaCl + O2
Decomposition (chlorate)
2NaClO3 --> 2NaCl + 3O2
Balance the equation: Pb(NO3)2 + KI --> KNO3 + PbI2
1,2,2,1
Type of reaction? Predict products? Balance?
silver nitrate + calcium chloride --> ??
What is double replacement?
2 AgNO3 + CaCl2 --> 2 AgCl + Ca(NO3)2
When I crush something up to speed up a reaction, I have increased the _________ of the substance
What is surface area?
Type of reaction? Predict products? Balance?
silver + calcium chloride --> ??
single replacement
Ag + CaCl2 --> no reaction
Balance the equation: H2S + Al(OH)3 --> H2O + Al2S3
3,2,6,1
Type of reaction? Predict products? Balance?
magnesium + phosphorus
What is combination?
6 Mg + P4 --> 2 Mg3P2
These two things must occur in for two molecules to react when they collide.
What is proper orientation and enough energy/speed?
Type of reaction? Predict products? Balance?
iron (II) phosphide + aluminum nitrate --> ??
Double replacement
Fe3P2 + 2 Al(NO3)3 --> 3 Fe(NO3)2 + 2 AlP
Balance the equation: C6H6 + O2 --> CO2 + H2O
2, 15, 12, 6
Type of reaction? Predict products? Balance?
iron (III) oxide + carbon --> ??
What is single replacement (smelting)?
2 Fe2O3 + 3 C --> 4 Fe + 3 CO2
When this is decreased there are less reactant particles present, thus less collisions take place and the reaction rate is slower.
What is concentration?
Balance this equation (difficult)
Cu + HNO3 --> Cu(NO3)2 + NO + H2O
3 Cu + 8 HNO3 --> 3 Cu(NO3)2 + 2 NO + 4 H2O
