Answer:
See explanations
Explanation:
a.	Molarity = moles/Volume in Liters = 5moles/2Liters = 2.5M in NaCl
b.	Freezing Pt Depression
      1.	Sprinkling salt on icy surfaces
     2.	Using antifreeze in automobile cooling systems
     3.	<em>Not an application
</em>
     4.	Using salt to make ice cream
c.	pOH = -log[OHˉ] = -log(1x10ˉ¹⁰) = -(-10) = 10 => pH = 14 – pOH = 14 – 10 = 4
d.	H₂O + NH₃ => NH₄⁺ + OHˉ => Bronsted Acid is H₂O  (proton donor)
 
        
             
        
        
        
Answer:
Iron remains = 17.49 mg
Explanation:
Half life of iron -55 = 2.737 years (Source)
 
Where, k is rate constant
So,  
 
 
The rate constant, k = 0.2533 year⁻¹
Time = 2.41 years
![[A_0]](https://tex.z-dn.net/?f=%5BA_0%5D) = 32.2 mg
 = 32.2 mg
Using integrated rate law for first order kinetics as:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D) 
Where,  
![[A_t]](https://tex.z-dn.net/?f=%5BA_t%5D) is the concentration at time t
 is the concentration at time t
![[A_0]](https://tex.z-dn.net/?f=%5BA_0%5D) is the initial concentration
 is the initial concentration
So,  
![[A_t]=32.2\times e^{-0.2533\times 2.41}\ mg](https://tex.z-dn.net/?f=%5BA_t%5D%3D32.2%5Ctimes%20e%5E%7B-0.2533%5Ctimes%202.41%7D%5C%20mg) 
![[A_t]=32.2\times e^{-0.610453}\ mg](https://tex.z-dn.net/?f=%5BA_t%5D%3D32.2%5Ctimes%20e%5E%7B-0.610453%7D%5C%20mg) 
![[A_t]=17.49\ mg](https://tex.z-dn.net/?f=%5BA_t%5D%3D17.49%5C%20mg) 
<u>Iron remains = 17.49 mg</u>
 
        
             
        
        
        
Answer:
thick, insulating fur
Explanation:
If an animal lives in a freezing climate, it makes sense logically that the animal would adapt and develop a layer of thick fur to keep its body insulated and maintain homeostasis.
