The volume = 6.71 L

<h3>Further explanation</h3>

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

V₁=7 L

T₁=25 °C(room temperature) + 273 = 298 K

T₂=12.5(halved) + 273 = 285.5 K

\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\\dfrac{7}{298}=\dfrac{V_2}{285.5}\\\\V_2=6.71~L

What test would be done to prove the color of specific compounds is due to metal ions apart from flame test
bulgar [2K]

Answer:

Borax bead test

Explanation:

Another test that can be used to identify colored ions in a specific compound such as salt is called "Borax bead test".

This test involves use of a clear glassy bead of borax that is joined together in a wire loop which is going to be involved in chemical reaction with the salts of certain metals.

This reaction will produce colors that we can use to identify the exact metal ions that are present.
