Hi , basically dominant alleles are always expressed in the organism , while recessive traits   tend to be expressed only when the dominant allele is not present. 
        
             
        
        
        
In a <u>Saturated </u>solution, the rate of dissociation equal to the rate of crystallization
Explanation:
A saturated solution is one than cannot dissolve any more solute because the solutes inter-molecular spaces are filled with the solute molecules at that temperature. When an attempt is made to dissolve more solute into the solution, the rate at which the solute is dissolved into the solution is equal to the rate at which excess solute is precipitated and crystallized. 
 
        
             
        
        
        
Because they are not on the periodic tsble they are on the back and they goes together
 
        
                    
             
        
        
        
Molarity=Moles of solute/Volume of solution in L
So
- 0.56M=moles/2.5L
- moles=0.56(2.5)
- moles of Iodine=1.4mol
Mads of Iodine
- Moles(Molar mass)
- 1.4(126.9)
- 177.66g
