Chemical Equations
Rates of Change
100
A substance that undergoes a chemical change.
What is a reactant?
100
A + B --> AB
What is synthesis reaction
100
XA + B --> BA + X
What is a single displacement
100
an equation that uses chemical formulas and symbols to show the reactants and products in a chemical reaction.
What is chemical equation?
100
A substance that changes the rate of chemical reactions without being consumed.
What is a catalyst?
200
The energy stored within atoms and molecules that can be released when a substance reacts.
What is chemical energy?
200
AB --> A + B
What is decomposition reaction?
200
AX + BY --> AY + BX
What is double-displacement?
200
Fe + S --> FeS
What is balanced equation
200
A protein that speeds up a specific biochemical reaction.
What is an enzyme?
300
A reaction in which energy is absorbed.
What is endothermic?
300
This refers to the decomposition of a compound by an electric current.
What is electrolysis?
300
A reaction that occurs when electrons are transferred from one reactant to another.
What is reduction/oxidation (redox) reaction?
300
2Mg + O2 --> MgO
What is unbalanced equation?
300
The state in which a chemical reaction and its reverse occur at the same time and at the same rate.
What is equilibrium?
400
A substance that is the result of a chemical change.
What is a product?
400
A reaction in which a compound and oxygen burn.
What is combustion reaction?
400
The fragments of molecules that have at least one electron available for bonding.
What are radicals?
400
CH4 + 2O2 --> CO2 + 2H2O
What is balanced equation?
400
The specific substance affected by an enzyme
What is substrate?
500
A reaction that releases energy (usually heat).
What is exothermic?
500
A reaction of at least two substances that forms a new, more complex substance.
What is synthesis reaction?
500
A reaction in which a gas, a solid precipitate, or a molecular compound is formed from the exchange of ions between two compounds.
What is double-displacement?
500
The smallest relative number of moles of the substances involved in a reaction.
