Why is the Nucleus' charge postive?
The Nucleus' charge is positive b/c it contains Protons with a positive charge and Neutrons with no charge.
Is this a Type I or Type II Binary Ionic Compound (BIC)?
"Calcium Hydroxide"
Type I b/c Calcium is a Main Group Element (A Gp).
Reaction where two smaller Compounds combine to form one larger Compound.
Synthesis Reaction

Identify what the shielding Effect is equal to.
Shielding Effect (SE) is equal to the # Core Electrons (#CE).
Name the BIC.
Ca(BrO3)2
Calcium Bromate
Which Reaction Type is this
P4(g) + 3O2(g)----> 2P2O3(g)
Synthesis Reaction
Write the fractions you would need to complete this calculation. Calculate the #mol H2 needed if 66.9 g O2 are used.
BCE=2H2(g)+ O2(g) ----> 2H20(g)
MM(H2)=2.02 g/mok, MM(O2)=32.00 g/mol
Fraction #1: (66.9 g O2 / 1)
Fraction #2: (1 mol O2 / 32.00 g O2)
Fraction #3: (2 mol H2 / 1 mol O2)
What is the equation to find the pH of a solution?
pH=-log[H+]
Explain trend for Atomic Radius (AR) going down a Group and why.
AR increases going down a Group because Valence Electrons (VE) occupy higher Principal Energy Levels (PEL), which extend further away from Nucleus.
Name the compound.
Si3N6
Trislilicon Hexanitride
Will this Reaction occur?
MgCl2 + 2Sn ---> 2SnCl+ Mg
NR
Why is calculating the limiting reactant important?
Calculating the limiting Reactant allows us to calculate the exact amount of Product produced.
What is the equation to find the pOH of a solution?
pOH=-log[OH-]
Describe the Trend in Ionization Energy (IE) as you move down a Group and why.
IE decreases as you move down a Group b/c VE are further away from the Nucleus due to increased Atomic Radius, making VE removal easier.
Which chemical Bond type do Type III Binary Compounds consist of?
Covalent Bonds
Separate each Reactant into its Cation and Anion, then determine the 2 Products using Ion Interchange.
NH4NO3(aq) + HCl(aq) ---> ?
Reactant #1: NH4+1(aq) + NO3-1(aq)
Reactant #2: H+1(aq) + Cl-1(aq)
Product #1: NH4Cl(aq)

Define a Bronsted-Lowry Base.
A Bronsted-Lowry Base accepts Protons from a Bronsted- Lowry Acid to form a Conjugate Acid and Conjugate Base.
What is the pH and pOH of a neutral solution?
Determine the #Atoms (#A) of each Element in the Compound: Pt(C6H5COO)3
Pt = 1
C = 18 + 3 = 21 (C is in 2 spots.)
H = 15
O = 3 + 3 = 6 (O is in 2 spots.)
