Draggable item		Corresponding Item
C2H4 + O2 --> CO2 + H20		Combustion
NABR + HPO4 --> NA3PO4 + HBR		Double Displacement
PBSO4 --> PBSO3 + O2		Decomposition
MG + FE2O3 --> FE + MGO

Required

What happens if the activation energy in a chemical reaction is not reached?

Required

1

Which side of a chemical equation are the reactants?

Required

1

What type of reaction is shown below?
CA(OH)2 + AL2(SO4)3 --> CASO4 + AL(OH)3

Required

1

Why is it important to balance a chemical equation?

1

What is this graph displaying?

Required

1

Which accurately describes the function of a catalyst in a chemical reaction?

Required

1

What would likely happen if you remove a catalyst from a chemical reaction?

5

Explain the graph above to me. (Including het vocabulary terms catalyst, activation energy, exothermic/endothermic)

Required

1

Are catalysts consumed in the chemical reactions they facilitate?

1

If you change the concentration of a substance, that means you are adding more of that substance to the same given volume. This will make the reaction slow down.

1

In an endothermic reaction, the products have less energy than the reactants because energy is released.

1

All reactions must have enough energy to start the reaction.

1

Increasing the surface area of the reactants will decrease the rate of the reaction.

1

Heat gives the reactant particles more energy. You can increase the surface area and concentration or also use a catalyst it speed up the reaction

When we increase the amount of concentration of a substance, how are we affecting the rate of reaction?

Required

Draggable item		Corresponding Item
Exothermic		An increase in this will typically increase the rate of reaction. It is measured by hot hot or cold a substance is.
Concentration		A material is used to decrease the speed of a chemical reaction.
Surface Area		The amount of substance in a given volume.
Endothermic		Lowers activation energy for the reaction to begin
Inhibitor		The minimum amount of energy needed for a reaction to take place.
Catalyst		This reaction will release heat into the surrounding area.
Temperture		This reaction will absorb heat from the surrounding area.
Activation Energy		The area of the chemical substances used in a chemical reaction.
