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:
78.125ml
Explanation:
Number of moles in 250ml of 2.5M KCl is (250÷1000)litres×2.5M so we divide these moles by 8M. The answer gotten will be in litres so multiply by 1000 to get it in ml
Heat: describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows.
Temperature:describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).Sep
