CORNELL NOTES 4.1
LEARNING OBJECTIVES Notes
Explain the different chemical
reactions.
Predict expected products in a
particular chemical reaction. CHEMICAL REACTIONS
Chemical Reactions
– These are chemical changes
What are Chemical Reactions? that result in the
transformation of one or more
substances into one or more
new substances.
What law does Chemical Chemical Reactions always follow
reactions follow? the Law of Conservation of
matter, wherein no atom both in
the reactant and product side is
changed.
What are the types of TYPES OF CHEMICAL
Chemical Reactions? REACTIONS:
• Oxidation-reduction (Redox)
reaction
• Precipitation
• Acid-base
REFLECTION
Chemical Reactions are chemical changes that result in the change of
composition or transformation of one or more substances into a new
substance.
Types of Chemical Reaction include Redox, Precipitation, and Acid-Base.
, REDOX REACTIONS
What are Redox Reactions? Oxidation-Reduction (Redox)
Reactions
– Chemical reactions involving
oxygen to form oxides.
What is the difference between PROPERTIES OF OXIDATION
Oxidation and Reduction? AND REDUCTION:
• In Oxidation:
What happened to the · Electrons and Hydrogen
electrons in Oxidation? atoms are Lost.
· Oxygen Combine and the
Does the Oxidation number Oxidation number
decrease or increase in increase.
Oxidation? ·
• In Reduction:
What happened to the · Electrons are gained and
electrons in Reduction? Hydrogen atoms are
combined.
Does the Oxidation number · Oxygen atoms are lost
decrease or increase in and the Oxidation
Reduction? number decrease.
Oxidation Number (O.N.)
What is O.N.
– The oxidation state of an
element in a compound.
The Oxidation number is also the
What does Oxidation Number
charge of its atoms that would
possess?
possess if the compound was ionic.
REFLECTION
Redox Reactions commonly involves oxygen to form oxides, but not all the
time.
Redox Reactions involves Oxidation (Loses electrons) and Reduction (gains
electrons.
Oxidation Number (O.N.) is the oxidation state of an element in a compound.
