Question 10

  • Highest ionization energy: He

    The first ionization energy varies in a predictable way across the
periodic table. The ionization energy decreases from top to bottom in
groups, and increases from left to right across a period. Thus, helium
has the largest first ionization energy, while francium has one of the
lowest. Ionization Energy sciaü https://www.angelo.ed

Question 11

  • Ni2+ is light green



Question 15

  • Lewis acid-base reaction and coordination complex

    Metal-Ligand Bond This bond is formed between a Lewis acid and a
Lewis base. The ligands (Lewis bases) have nonbonding electrons. The
metal (Lewis acid) has empty orbitals. Che stry of Coordination

    The Lewis Acid-Base Concept:Coordination Compounds. In a Lewis
acid-base neutralization, the base donates a pair of electrons forming
a coordinate covalent bond which joins the two species together into
the reaction product. The Lewis Acid Base Concept: Coordination

Question 28

Esters General Formula: R-C-O-R' General Formula: R-O-R'

Question 34

  • Hydrogen bonding in N2H4


Question 40

  • Beta plus decay vs. Beta minus decay

    Carbon- 14 6 protons 8 neutrons Carbon- 1 0 6 protons Beta-minus
Decay Nitrogen- 14 Antineutrino Electron 7 protons 7 neutrons
Beta-plus Decay Boron- 1 0 5 protons Neutrino Positron
