Answer:
0.11mole
Explanation:
Let us assume that the condition is at standard temperature and pressure(STP); 
  Given parameters: 
         Volume of water  = 2.45L 
 
    Unknown: 
        Number of moles found in this volume of water  = ? 
Solution; 
  At STP; 
                  Number of moles  = 
  Input the parameters and solve; 
                   Number of moles of water  =  = 0.11mole
   = 0.11mole
The number of moles of water found is  0.11mole
 
        
             
        
        
        
It would have a solubility substance and surface
        
             
        
        
        
The species that is the conjugate acid is HC₂H₃O₂(aq). The correct option is d.
<h3>What are conjugate acid?</h3>
Conjugates acids are those acids which are made when an acid donates a proton to a base according to Bronsted Lowry theory.
In other words, we can say that it is an acid with hydrogen ion. An example is  water (base) reacting with an acid to form the hydronium ion (conjugate acid).
Thus, the correct option is d, HC₂H₃O₂(aq).

Answer:
cis-3-hexene and trans-3-hexene
Explanation:
Hydroboration oxidation is a method of preparation of alcohol from alkene. 
Hydroboration follows anti-Markovnikoff rule in which alcohol group attached to less substituted carbon. Stereochemistry of the product is always syn that is H and OH attached to the same side of the double bond. 
cis-3-hexene and trans-3-hexene undergoes hydroboration to form 3-hexanol.
