In the process of ionization, what is the relationship between the second ionization energy (I2) and the third ionization energy
dimulka [17.4K]
<span>The first ionization energy is the energy that is obligatory in order to eliminate the first electron from an atom(neutral) in the GAS phase
, the second ionization energy is defined as  the energy required to remove the second electron from an atom(+1 ion) in the GAS phase.
</span>the third ionization energy is the energy it takes to remove an electron from a 2+ ion. (That means that the atom has already lost two electrons, you are now removing the third.) 
<span> Ionization energy will normally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods
hope it helps</span>

Carbon and oxygen combine to form carbon dioxide. What are the reactants, or what
MariettaO [177]

Answer:

The correct option is d: carbon and oxygen.

Explanation:

The reaction between carbon and oxygen to form carbon dioxide is:

C + O₂ → CO₂    (1)

 

On the left side of the above reaction (1), we have the reactants, which are carbon (C) and oxygen (O₂) that react to form carbon dioxide (CO₂), which is the only product of the reaction (on the right side of the reaction).      

     

Hence, the correct option is d: carbon and oxygen.

I hope it helps you!
