   When  sodium chloride  is formed  from a positively charged sodium atom and a  negatively  charged  chlorine  atom,  the charge  on the salt becomes  neutral   is true
  Explanation
 Sodium  ion ( positively  charged)  combine with chloride  ion ( negatively charged)  to  sodium chloride which  is neural  according  to equation below.
 Na⁺   +  Cl⁻    →  NaCl  (<em>neutral</em>) 
Equal  number  of positive  and negative  charges  add up to make neutral  Nacl therefore the statement above is true.
 
        
                    
             
        
        
        
Answer:
Decrease in competition from other plants.
Explanation:
Decrease in competition from other plants is the environmental factors likely leaf to the exponential growth seen in fireweed after the Yellowstone wildfires because decrease in population from other plants will lead to a particular species dorminating a particular geographical area and this dorminating species are Dorminant when competition has been reduced by wild fire and this will lead to exponential growth where the available resources will be abundance or unlimited or resources increases.
