Chemical Eqs.
This arrow in a chemical equation means this.
What is "yields" or "produces?"
Balance the following equation:
__LiCl + __Br2 --> __LiBr + __Cl2
2LiCl + Br2 --> 2LiBr + Cl2
An endothermic reaction is one that does this.
What is absorbs heat?
What is temperature?
C2H2 is burned in the presence of oxygen.
Complete the chemical equation:
__C2H2 + O2 -->
Balance if necessary, classify the type of reaction.
2C2H2 + 5O2 --> 4CO2 + 2H2O
Combustion
Each substance on the LEFT side of a chemical equation is one of these.
What are "reactants?"
Balance the following equation:
__KClO3 --> __KCl + __O2
2KClO3 --> 2KCl + 3O2
N2 + O2 --> N2O5 is this type of reaction.
What is synthesis?
What is concentration?
The numbers that go before symbols and formulas in a chemical equation are called this.
What are coefficients?
Balance the following equation:
__N2 + __O2 --> __N2O5
2N2 + 5O2 --> 2N2O5
KClO3 --> KCl + O2 is this type of reaction.
What is decomposition?
Crushing would increase this factor and allow particles to interact with each other and react more frequently.
What is surface area?
The Law of Conservation of Mass states this.
What is matter cannot be created or destroyed?
Balance the following equation:
__CH4 + __O2 --> __CO2 + __H2O
CH4 + 2O2 --> CO2 + 2H2O
LiCl + Br2 --> LiBr + Cl2 is this type of reaction.
What is single replacement?
Increasing this factor decreases the volume which makes collisions and reactions more frequent. This factor only affects gaseous reactants.
What is pressure?
Write the chemical equation for the following:
Magnesium reacting with chlorine to produce magnesium chloride.
Mg + Cl2 --> MgCl2
Balance the following equation:
__Ca(OH)2 + __H3PO4 --> __Ca3(PO4)2 + __H2O
3Ca(OH)2 + 2H3PO4 --> Ca3(PO4)2 + 6H2O
Ca(OH)2 + H3PO4 --> Ca3(PO4)2 + H2O is this type of reaction.
What is double replacement?
Adding one of these lowers the activation energy, allowing reactions to start more easily.
What is a catalyst?
