Explanation:
Usually to identify halide ions in solution you use silver nitrate which readly react with Cl⁻, Br⁻ and I⁻ ions to form silver halide salts with different colors depending on the ion present in the solution.
Now, because the silver halide salts are insoluble in water and have a density higher that the water they will stay in the lower part of the test tube.
Answer:
25
Explanation:
25 may or may not be right im not the best with measuring math stuff but i did
50x2 which is 100 i then divided that by 2 for the 50 again which was a little pointless then i just divided 50 by 2 which we all know to be 25
hope this helped if not really really sorry
I guess it is called an Equation !!
Answer:
