Slide 1
• The individual pictured here came up with the concept that a mole contains 6.02 x 1023 particles of that substance. This number was also named after him.
Slide 1
Decreasing the temperature under which a chemical reaction takes place will do this
to the rate of the reaction
Slide 1
Increasing the surface area of the reactants that are exposed to each other in a
chemical reaction will usually do this to the rate of the reaction
Slide 1
This machine would do this to the rate of the
chemical reaction between the stains in your clothes and the
detergent
Slide 1
A lower concentration of reactants in a chemical reaction would result in this type
of change in the rate of the reaction
Slide 1
In the following chemical formula the Vanadium oxide (V2O5) acts as this in this
chemical reaction.
V2O5
2SO2 + O2 → 2SO3
Slide 1

Who is Avagadro
• The individual pictured here came up with the concept that a mole contains 6.02 x 1023 particles of that substance. This number was also named after him.
Slide 1
For 40 points: What is 1.5 moles
This is the number of moles contained in 270 grams of glucose
C6H12O6
Slide 1
For 10 points: What is 4 moles
This is the number of moles of H2SO4
I would have if I had 392 grams of this substance
Slide 1
For 10 points: What is an exothermic reaction
This type of chemical reaction releases energy into the environment
Slide 1
For 30 points: What is an endothermic reaction
This type of reaction takes energy from the environment
Slide 1
For 10 points: What is slow down the reaction
Decreasing the temperature under which a chemical reaction takes place will do this
to the rate of the reaction
Slide 1
For 20 points: What is speed up the reaction
Increasing the surface area of the reactants that are exposed to each other in a
chemical reaction will usually do this to the rate of the reaction
Slide 1
For 30 points: What is speed up the reaction
This machine would do this to the rate of the
chemical reaction between the stains in your clothes and the
detergent
Slide 1
For 40 points: What is reverse or slow down the reaction
A lower concentration of reactants in a chemical reaction would result in this type
of change in the rate of the reaction
