Explanation:
Balanced chemical reaction equation will be as follows.
      
In human body, the neutral iron changes into 
(aq) cation. There will be an oxidation-half reaction and a reduction-half reaction. Equations for this reaction are as follows.
Oxidation: 2Fe^{2+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + 2e^{-}[/tex] .... (1)
Reduction: 
 ...... (2)
On adding both equation (1) and (2), the overall reaction equation will be as follows.
      
Therefore, neutral iron is a part of Heme - b group of Hemoglobin and in an aqueous solution it dissolutes as a part of Heme group. Hence, then it becomes an 
 cation.
 
        
             
        
        
        
Answer:
a
. eight tenths of her cookies
Explanation:
Let the total number of Lakesha's cookies be represented by x.
So that;
She gave three tenths to Bailey = 
 of x
                                                      = 
She gave five tenths to Helen = 
 of x
                                                   = 
Fraction of Lakesha's cookies given away = 
 + 
                                                       = 
                                                       = 
Thus, the fraction of cookies given away by Lakesha is 
.
