There is no reaction. In water the both salts will dissociate in there ions. Na+, Cl- , K+ and Br-.

The Link is broken.

How to get Ion like S 2-. The 2- in exponent.
Attachment of PDF is it possible?

Impossible.
You can attach img, or URL. Icon on top.

What is CH_1.74 O_0.323 N_0.07? Better is to give the formula of the fuel like C8H18 Octane.

You need 1 mol of the given organic compound and 6 mol of oxygen according the equation. This gives a Ratio 1:6.

1:6

CO2 to O2 1:1
C4H9OH to O2 1:6

Nitrogen and water mainly developed.

Google helps

Magnesium and sodium exchange each other. So get magnesium phosphate and sodium sulfate.
Now its your work.

Check the specific gravity. If both peace same volume then you can weight it. Chemical analyses are more complicated and Beryllium is very poisson and carcinogen better don't touch it or work with. It.
