The measure of the kinetic energy of the particles of a substance is called
heat
calorimetry
temperature
pressure
When temperature decreases
energy increases
molecules move faster
more collisions occur
molecules move slower
6CO2 + 6H20 + Energy ---------------> C6 H12 06 + 6O2
endothermic reaction
exothermic reaction
What happens in a chemical reaction?
Bonds between atoms break and/or are formed
New atoms are created and/or removed
Protons move from one atom to another
Electrons change into protons
Heat + Ice --> Liquid water
Endothermic
Exothermic
Both Exo and Endo
Neither Exo or Endo
Which statement describes the energy and bonding changes as two atoms of fluorine become a molecule of fluorine?
Energy is absorbed as a bond is broken
Energy is absorbed as a bond is formed.
Energy is released as a bond is broken.
Energy is released as a bond is formed.
Hydrochloric acid reacts faster with powdered zinc than with an equal mass of zinc strips because the greater surface area of the powdered zinc
decreases the frequency of particle collisions
decreases the activation energy of the reaction
increases the frequency of particle collisions
increases the activation energy of the reaction
Based on Table I, which equation represents a reaction with the greatest difference between the potential energy of the products and the potential energy of the reactants?
4Al(s) + 3O2(g) → 2Al2O3(s)
2H2(g) + O2(g) → 2H2O()
C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O()
C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O()
Given the equation on Table I :
C (s) + O2 (g) --> CO2 (g)
Choose the correct reaction including the Heat value.
C (s) + O2 (g) --> CO2 (g) + 393.5 KJ
393.5 KJ + C (s) + O2 (g) --> CO2 (g)
566 KJ + C (s) + O2 (g) --> CO2 (g)
C (s) + O2 (g) --> CO2 (g) + 566 KJ
