When heated, kclo3 decomposes into kcl and o2. if this reaction produced 88.4 g of kcl, how much o2 was produced (in grams)? > 2kcl+3o_2. a) 2(kclo_3)=245.096 b) 2kcl=149.102g c) 3o_2=95.995

Mass of KCl=          88.4g 
Molar mass of KCl=39+35.5 
                                =74.5 
 The Moles of KCl= 88.4/74.5
                            =1.186
If for  the 2 moles of KCl there are 3 moles of oxygen
so

1 mole of KCl will  give=3/2=1.5 moles of oxygen 

1.186 moles of KCl will give =1.5*1.186=1.779 oxygen
32 the molar mass of oxygen
so its mass will be
1.779 *32=56.928

Hence, closer is the number of neutrons to the number of protons more stable will be the nucleus. Thus, we can conclude that a nuclei with 10 protons, 12 neutrons would be the most stable.
