Hello student in this question in the first part okay it is given that k2 s4 okay k2 s of 4 react with c and it is n o 3 and it is 2 okay and this is react when they both react okay they both react and this give both this give 2 kno3 plus this is cn s o 4 okay so this is what type of reaction so here it is double displacing okay this one is double displacement we have to find the precipitation so this is what this is double displacement so this is not a required answer.

Now if we consider for the second part, this is n -a -c -l -4, okay, plus it is reacting with n -h -42 -s, it is in a quos form.
00:41
And this gives 4 this gives to n -h -4 -4 plus this is n -a2s.

So what type of reaction is this? so this is again what? double displacement reaction, okay? double displacement reaction, right? so this is also not our required answer.

Now if we consider for the third part, okay, the reaction is mg n -o -3 and 2, okay, and it is reacting with n -a -2 -c -o -3, and this gives what? this gives m -g -c -o -3 and this form the precipitate plus this is 2 -a -no3...
