The best explanation, though it's controversial, is that a great flood had once covered the earth for a brief period of time.
I believe the answer is an explosion
They speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.
Explanation:
- F Cl Br
- ionization energy decreases we move down the group
- so Br<Cl<F
2. Na K Li
- ionization energy decreases we move down the group
- so K<Na<Li
3. C N O F
- ionization energy increases as we move across the peroid
- so C<N<O<F
