AND ANSWERS EXPERT VERIFIED
●● Electron configuration for anions.
Answer: Add 1 to closest orbital
Cl- = [Ne]3s^2 3p^6
●● Atomic orbitals.
Answer: s, p, d, f
●● Primary vs secondary structures of proteins.
Answer: Primary - AA chain (linked by peptide bonds)
Secondary - stabilized by non-covalent bonds (alpha helices & beta
sheets)
●● Most bonds in organic compounds are.
Answer: covalent
●● Properties of water.
,Answer: 1. polar
2. capable of adhesion and cohesion
3. high heat capacity (so it's hard to raise its temp)
4. great solvent
5. high heat of vaporization (allows humans to cool off via sweat)
6. water is less dense as a solid than a liquid
●● Intermolecular forces of water.
Answer: hydrogen bonding
●● Solution components.
Answer: 1. solvent (product being dissolved)
2. solute (medium for dissolving solvent)
●● Molarity.
Answer: the number of moles of solute per liter of solution
●● Solubility rules.
Answer: SOLUBLE
1. alkali metals (group 1) & NH4+ cations
2. NO3- or CH3COO- anions
3. Cl, Br, I (except when bonded to Ag+, Pb2+ or Hg2+)
,4. sulfate ions (except when with Ca2+, Sr2+, Ba2+, Pb2+)
INSOLUBLE
1. Metal oxides (except CaO, SrO, BaO)
2. Hydroxides (except when with Ca2+, Sr2+, Ba2+)
3. Carbonates, phosphates, sulfides, and sulfites (unless bound to alkali
metal or NH4+)
●● Solubility product.
Answer: Ksp = [A]^a[B]^b
**only products because we don't include solids in the equilibrium
expression
for NaCl
- Ksp = x^2
for PbCl2
- Ksp = 4x^3
for Cr(OH)3
- Ksp = 27x^4
, ●● Large Ksp means.
Answer: strong electrolyte (more soluble)
●● Strong acids.
Answer: So I brought no clean clothes
1. H2SO4
2. HI
3. HBr
4. HNO3
5. HCl
6. HClO4
7. HClO3
●● Strong bases.
Answer: 1. NaOH
2. LiOH
3. KOH
4. CsOH
5. RbOH
6. Ba(OH)2
7. Ca(OH)2
