Answer:
solar energy and chemical energy
Hi There! :)
<span>Which elements in the periodic table are metalloids or have semimetallic properties?
</span><span>Boron, Silicon, Germanium, Arsenic, Antimony, and Polonium are all metalloids. Some people consider Astatine a metalloid</span>
Explanation:
As molarity is the number of moles placed in a liter of solution. Therefore, no. of mole = Molarity × volume of solution in liter
Hence, moles of
will be calculated as follows.
No. of mole of
=
= 0.0168 mole
According to the given reaction, 2 mole of
react with 4 mole of KI.
Therefore, for 0.0168 mole amount of
required will be as follows.
=
= 0.0337 mole of KI
Hence, volume of KI required will be calculated as follows.
Volume = 
Volume of KI =
= 0.1614 liter
= 161.4 ml (as 1 L = 1000 mL)
Thus, we can conclude that 161.4 ml volume of a 0.2089 M KI is required for the given situation.
