1. because eventually the grass/food they are eating will loose its nutrients from eating it all the time and they need to migrate to find better food
2. the weather
3. their predators may migrate to the place they are and they need to migrate in order to have a better chance of survival
hope this helps these are just some reasons just ask if you need anymore
Answer:
B.) 6
Explanation:
Attached below is the Lewis structure of PCl₃ . Since phosphorus (P) has 5 valence electrons and chlorine (Cl) has 7 valence electrons, there should be 26 valence electrons (5 + 7(3) = 26) in the Lewis structure.
Bonding electrons are the electrons present in the chemical bonds between two atoms.
There are 2 electrons shared in every single bond. Within PCl₃, there are 3 single bonds. As such, there are 6 bonding electrons in the Lewis structure of PCl₃.
Explanation:
0.00208 is the correct standard form
V= d/t
v=speed
d=distance
t=time
So v= 422/3
v =140.667m/s
<span>Majorly there are four types of inter molecular forces:
Permanent dipole (like in HCl or NaCl)
Ion dipole and Ion induced dipole
Hydrogen bonding
Van der Waals forces (Keesom, Debye, and London dispersion force)</span>
