B. Lower elements have more energy levels
Explanation:
Ionization energy decreases down the group because lower elements have more energy levels. Therefore, the pull of the nucleus on the outermost shell electrons is not so great.
- Ionization energy is the energy required to remove an electron from an atom.
- It is a measure of the readiness of an atom to lose an electron.
- Down a group or family, atomic radius increases due to addition of more electronic shells or energy levels.
- As the atomic radius becomes larger, the ionization energy reduces.
- This is because of the increased shielding/screening effect of inner shell electrons on the electron to be removed from the nuclear attraction.
- This way, its takes a lesser amount of energy to remove them as shielding effects increases down the group.

Fermentation would occur in muscles because only your muscles can produce lactic acids, which cause pain or otherwise lactic acid fermantation
Answer:
0.034 M
Explanation:
1/[A] = kt + 1/[A]o
[A] = ?
k= 0.04556
t= 10.0 minutes or 600 seconds
[A]o = 0.50 M
1/[A] = (0.04556 × 600) + 1/0.50
[A] = 0.034 M
