Behavioral Adaptation is something that is natural in animals that are used for survival. Example: Birds Migrating north during the winter.
Hey there!:
The 1s, 2s and 2p subshells are completely filled (a maximum of two electrons go into the 1s subshell and a maximum of two electrons go into the 2s subshell. The 2p subshell includes 3 orbitals, with 2 electrons maximum per orbital). The 3s subshell has only one of a maximum of two electrons.
Hope that helps!
Answer:
1,2,3
Explanation:
Heat gain implies that heat is absorbed by the system in order to make the stated phase transition possible.
Before a liquid changes to gas, intermolecular forces in the liquid are broken by energy supplied as heat.
Also, transition from solid to liquid requires energy to break intermolecular bonds.
Finally, sublimation requires input of energy in the form of heat.
Answer:
156.4g K
Explanation:
I'm not sure if it is correct but I think it should be this
What do we know so far?: 2K + 1Cl2 -> 2KCl, 2 mol of Cl2
What are we looking for?: #g of K
What is the ratio of K to Cl2?: 2:1
Set up equation: 2molCl2 x 
Cancel unwanted units: 2 x 
Answer we got: 2 x 2mol K = 4mol K
Converting moles to grams: 4 x 39.1 (molar mass of K) = 156.4g K
Answer:
0,0,0,0
Explanation:
The formal charge formula:

So:
Hydrogen: 1 elec. of valence and shares two electrons with the O

Oxygen: 6 elec. of valence, 2 lone pairs and shares two electrons with the H and two with the F

Fluorine: 7 elec. of valence, 6 lone pairs and shares two electrons with the O

Oxygen: 6 elec. of valence, 3 lone pairs

Note: the dative bond between F and the second O doesn't count as shared electrons.
