Answer:
C. Solubility
Explanation:
Solubility. A physical property does not change the chemical compostion. Solubility can be observed, unlike the others.
The reaction for the decomposition of Manganese(II) iodide when exposed to light to form manganese and iodine is MnI2 → Mn + I2.
<h3>THE DECOMPOSITION OF MANGANESE (II) OXIDE:</h3>
- Manganese II iodide has the chemical formula of MnI2. Manganese II iodide can be decomposed in the presence of light to form manganese and iodine.
- The balanced chemical equation of the decomposition is as follows:
MnI2 → Mn + I2
Therefore, the reaction for the decomposition of Manganese(II) iodide when exposed to light to form manganese and iodine is MnI2 → Mn + I2.

Answer:
M = 33.6M .
Explanation:
Hello there!
In this case, according to the definition of molarity which is computed by dividing the moles of solute by the liters of solution, it is possible to realize that the moles of the solute are 12.6 mol and the liters of solution are 375/1000= 0.375 L and therefore the molarity of the solution can be calculated as follows:
Which has molar units, M.

Answer:
pOH = 5
pH = 9 → Solution is basic
Explanation:
We need to know that:
pH + pOH = 14
< 7 ⇔ pH = 7 ⇔ > 7
Acidic Neutral Basic
pOH = - log [OH⁻] → - log 9.8×10⁻⁶ = 5.00
pOH = 5
pH = 14 - 5 = 9
