What is The Octet Rule?
Every MGE wants to have 8VE to be stable.
For most Atoms, Energy builds up more Energy when VE is added to Atom.
True or False?
False
Energy is released when VE is added to Atom.
What is a Synthesis Reaction?
Rxn where 2 simple substances combine to form 1 Compound.
What is the UBCE of 4Ga(s) + 3S2(g)?
UBCE = 2Ga2S3
Due to Gravity, what happens in the Atmosphere?
Lower Air Density, Higher Altitude.
#P+ = #e-
True Or False?
False
#P+ does not = #e-
higher Energy Affinity (EA) has higher negative EA value.
True or False?
False
Energy is released, EA value decreases.
What is the Product of Fe+2(aq) + 2Cl-1(aq)
How much heat does Earth's surface absorb?
Absorbs heat to 35o C. higher than otherwise.
#A GP = #VE
True or False?
True
What is the Periodic Table trend for MGE?
Group of EA moves down
Period moves right
What does Cation + Anion make?
Ionic Compound (IC)
What are the Hydrogen Ions (H+1) in an Aqueous Solution?
Where do most GGE originate from?
GGE originates mostly from Housing, Transportation, Food, and Related Industries.
What is the Electronegativity range?
EN range = 0.7 - 4.0
Cation is a Metal
Anion is a Nonmetal
What is a Double Displacement Reaction (SDR)?
Rxn where 1 Metal replaces another Metal in a Compound.
What is the base in a Bronsted-Lowry Model?
What is true about the 2 major components of Earth's Atmosphere, N2 and O2.
N2 and O2 do not contribute to Atmospheric warming due to their molecular structure.
What is the definition of Valence Electrons (VE)?
Outer e- farthest from Nucleus that forms CB with other Atoms.
What is the BIC for Zinc (II) Arsenite?
Zn+2 AsO3-3
What operation do we use to convert from #mol A --> #mol B?
Mole Ratio
What is the BCE of Na+1(aq) + SO4-2(aq) + Pb+2(aq) + 2NO3-1(aq)
BCE:
Na2SO4(aq) + Pb(NO3)2(aq) ---> 2NaNO3(s) + PbSO4(aq)
What is Le Chatelier's Principle?
If a Chemical System at Eq experiences a disturbance, it changes the way it counteracts the change as if it returns to CEq.
