Answer:
Freezing point is -2.81°C
Explanation:
34g/342gmol^-1 = 0.0994mol
n = m/mr
Molarity= 0.994/ 0.66 = 1.51M
◇T = -i × m ×Kf
Where ◇T is freezing depression 
i= Vant Hoff factor
m = molarity
Kf = freezing content = 1.
860kgmol^-1
◇T =-1 × 1.51 × 1.860 = - 2.81°C
 
        
             
        
        
        
Unlikely. It's unlikely for ammonium ion 
 to accept a proton 
 and act as a Bronsted-Lowry Acid. 
<h3>Explanation</h3>
What's the definition of Bronsted-Lowry acids and bases?
- Bronsted-Lowry Acid: a species that can donate one or more protons 
 in a reaction.  
- Bronsted-Lowry Base: a species that can accept one or more protons 

 
Ammonium ions 
 are positive. Protons 
 are also positive. 
Positive charges repel each other, which means that it will be difficult for 
 to accept any additional protons. As a result, it's unlikely that 
 will accept <em>any</em> proton and act like a Bronsted-Lowry Base.
 
        
             
        
        
        
D, since the anther is a male organ
        
             
        
        
        
N = cv 
1.46 = 0.1 x v
v = 1.46/0.1
v = 14.6 (litres if it’s moles per litre)
