Explanation:
1. N/A
2. The difference in color
3. It is making the solution less concentrated, usually by adding more liquid.
4. You need to find the concentration of the solution before it was diluted. Add more of the solvent to the solute as per needed.
5.
a 1 molar solution cannot be made by adding one mole of solute to 1 L of solvent. • Solutions of a desired molality are usually prepared by placing the appropriate amount of solute

Explanation:
Potassium iodide reacts with oxygen in presence of water to produce potassium hydroxide and potassium diiodoiodate(I) .
5KI + 2H₂O + O₂ =4 KOH + I₂ + K(II₂) .
Answer:
The balance equation is
→ 
Explanation:
first, we have to make sure that the atoms are balanced
→ 
→ 
then we proceed to balance charges of each half-reaction
→
→ 
Now we multiply the half-reactions to match the number of electrons in each one
( → )x2
( → )x3
and now we do the sum of the half-reactions
2
→ 2
→ 3 
→
note: the only atom that needed to be balanced was I
