Vocabulary
The substances formed during a chemical reaction
What are products?
The number written in front of a chemical formula to balance a reaction
What are coefficients?
Al + O₂ → Al₂O₃ is an example of this type of equation
What is synthesis?
Equilibrium is the state in which the forward and reverse reactions occur at the same _____
What is rate?
3 signs of a chemical reaction
What is color change, temperature change, gas, bubbles, light, fire, etc...
These numbers are not changed when balancing chemical equations
What are subscripts?
This chemical reaction has the generic formula of: AB → A + B
What is a decomposition reaction?
If more reactant is added, equilibrium shifts in this direction
What is towards the products (to the right)?
In the chemical reaction, Mg + O → MgO, the Mg and O are called these
What are reactants?
These are the 2 products of a combustion reaction
What are CO2 and H2O?
If product is removed from a system at equilibrium, the reaction shifts in this direction
What is towards the products (to the right)?
A disturbance to a system at equilibrium is called this
What is a stress?
This type of reaction: 2Na + 2H₂O → 2NaOH + H₂
What is a single replacement reaction?
If there are 2 oxygen atoms on the reactant side but 4 on the product side, you would place this coefficient in front of O₂ on the reactant side.
What is 2?
When ions from 2 compounds switch places, this type of reaction occurs.
What is a double replacement reaction?
Heat is on the product side in this type of reaction (releases heat)
What is exothermic?
This term refers to a substance that has been dissolved in water
What is an aqueous solution (aq)?
SiO₂ + HF → SiF₄ + H₂O is an example of this type of equation
What is double replacement?
The balanced form of the reaction H₂ + O₂ → H₂O
What is 2H₂ + O₂ → 2H₂O?
These two reactions are opposites of each other
What are synthesis and decomposition?
A + B ⇌ C. Adding more C causes the reaction to shift this direction
What is to the left?
