B. because the other options are different sciences (biology and entomology)
Hello,
Here is your answer:
The proper answer to your question is that "the particles will rather speed up or slow down depending on what type reaction".
If you new anymore help feel free to ask me!
Hope this helps!
I think it takes about 2 weeks to go from H to B on the diagram since H is the new moon and B is the full moon so going from H to B represents half of the lunar cycle and one lunar cycle takes about 28 days (which is about 4 weeks).
2 F atoms
Explanation:
A Ca atom has a valence number of +2, which means that when ionized, it will give up two electrons. In turn, a F atom has a valence number of -1, which means it can only accept 1 electron when ionized. So to accommodate the two electrons from Ca atom, we need 2 F atoms.
