Oooooxidation
Rule #1?
The Free Element Rule: If an element is alone (N, Fe, Ti, H), its charge can be assumed 0
What is a group of slow bears called?
A sloth, or a sleuth
Binary Covalent Compounds
Two Nonmetals bonded
1C + 1O2 -> 1CO2
The abbreviation for Oxidation Numbers is not ON, because this looks too much like Oxygen Mononitride. Instead, it is OXN.
Rule #2 is called the Ion Rule. What does this mean?
The amount of electrons needed to be lost or gained dictates the charge. F needs one more, so 1-. Mg needs to lose two, so 2+
Despite us using it to describe many different animals, a 'swarm' is specific to what flying creature?
Bees
Oxyanions:
Two-element ions with an Oxygen
AlN + OH -> NO2 + AlH2
1 AlN + 2 OH -> 1 NO2 + 1 AlH2
The fifth Oxidation Rule states that polyatomic ions get their charge from all the elements within combining their charges.
Does this compound follow or break Rule #3? Why?
AlO2
The sum of the charges in a compound must be zero.
Al is 3+, O is 2-. These combine to be -1. NOPE.
Perhaps due to their rhythmic chest drumming, a group of gorillas is called a
Band
Hydrates / Anhydrous
Has an H2O
Does not have any H2O
Diatomic Nitrogen combines with Carbon Dioxide to create NO3 and Non-Diatomic Carbon Gas
1 N2 + 3CO2 -> 2NO3 + 3C
NO!
All of everything is always written so it can be balanced!
Give the oxidation number of each element:
H2SO4
H = 1+
S = 6+
O = 2-
We get a figure of speech AND a game from the name for a group of monkeys:
A barrel!
Binary Acid, Ternary Acids
Hydrogen and another nonmetal
Hydrogen, Oxygen, and another nonmetal
2Fe + 1H2O2 -> 2FeO + 1H2
A metal bonded with an Oxygen must have a charge of 2+
NO!
Al2O3 : Each O has a 2-, but each Al has a 3+.
Rule 4 says that Oxygen has an oxidation number of ____, unless it is ____________ or it is ______________. In the latter two, the charge is either _____ or _____.
2-
Peroxide (H2O2)
OF
1- or 2+
Due to their dark nature, a group of ravens is called:
An unkindness
Oxidation Number
The number of electrons an atom must gain or lose to become neutral
Al2S3 breaks down into Aluminum and Octasulfide.
8 Al2S3 -> 16 Al + 3 S8
Lithium and Flourine create LiF2, due to alkali metals slightly changing charge when in the presence of highly electronegative elements.
Falso
