Required

1

This image above best represents what type of chemical reaction? Explain your answer.

Required

1

What does activation energy refer to in a chemical reaction?

Required

1

How does a catalyst affect the activation energy of a reaction?

Required

1

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

Required

1

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

Required

1

Match the vocabulary terms to the correct definition.

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

The human body has chemical reactions happening all the time. If we increase this in your saliva the food in your mouth will break down faster.
