Answer:
The water potential of a solution of 0.15 M sucrose solution is -3.406 bar.
Explanation:
Water potential = Pressure potential + solute potential 


We have :
C = 0.15 M, T = 273.15 K
i = 1 
The water potential of a solution of 0.15 m sucrose= 
 (At standard temperature)


The water potential of a solution of 0.15 M sucrose solution is -3.406 bar.
 
        
             
        
        
        
Planck suggested that light/energy was absorbed/released in certain amounts, called quanta.
        
                    
             
        
        
        
Ionic or electrovalent compounds support the theory of ionic bonding because they are compounds composed of charged particles formed when an atom gains or loses electrons. 
Electrovalent compounds posses:
- High boiling and melting points.
 - Form crystals.
 
<h3>What is ionic bonding?</h3>
This is the transfer of valence electrons from metals to non metals to form ionic compounds. It also refers to a chemical bond formed between two ions with opposite charges.

Answer:
Nuclear fusion is when two atomic nuclei combine and form one nucleus. Nuclear fusion generates all of the Sun's energy. Inward pulling by the Sun's gravity is counteracted by outward pushing by the Sun's nuclear fusion; this balance keeps the sun from collapsing or exploding.
