Answer:

-) Oxidizing agent: 
-) Reducing agent: 
Explanation:
The first step is separate the reaction into the <u>semireactions</u>:
A.
B.
If we want to balance in <u>basic medium </u>we have to follow the rules:
1. We adjust the oxygen with 
2. We adjust the H with 
3. We adjust the charge with 
Lets balance the first semireaction A. :

Now, lets balance semireaction B:

Finally, we have to add the two semireactions:

Cancel out the species on both sides:

Simplifying the equation :

The
is <u>oxidized</u> therefefore is the <u>reducing agent</u>. The
is<u> reduced</u> therefore is the <u>oxidizing agent</u>.
The most common isotope of hydrogen is H¹ and this isotope has 0 neutrons
The equation ΔHsoln = ΔH1+ΔH2+ΔH<span>3 means that either the solution is endothermic (</span>ΔH < 0, the resulting reaction is cold) or exothermic (ΔH>0, the resulting reaction is hot). The lattice energy can be solve through this equation,
<span>lattice energy = </span>ΔHsolvation - IMF - ΔHsoln<span>
</span>
Answer:
Explanation:
A group of atoms bonded together and the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. They are made up of atoms that are held together by chemical bonds. These bonds exchange electrons among atoms.
