(i) Hydrogen chloride gas is prepared by treating Sodium chloride with concentrated sulphuric acid. The HCl gas is passed through a drying agent to remove moisture where concentrated sulphuric acid plays the role of dehydrating agent as well.
(ii) NaCl+H2
SO4 →NaHSO 4

Hope it helps :)
Hola!
→ Your query:
Atoms of one element easily changes to atoms of another element. Is it True? or False?
→ The answer is: TRUE
→ Reason :
We can change atom of one element to other atom by adding more particles into them. ex : Neutron, Protons and Electrons.
This is how nuclear fusion works.
hope it helps!
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.
