Answer:
B) conducts electricity
Explanation:
Metals are conductors, literally meaning they conduct electricity.
One metal is liquid at room temp (there might be one more but I only know of mercury).
The reactivity depends on the placement in the periodic table.
If it conducts electricity, it can't be an insulator.
Iron (III) chloride catalyzes the decomposition of hydrogen peroxide because the decomposition of hydrogen peroxide is usually inhibited by the presence of ions such as phosphate ions in solution. The iron ions that would result from the dissolution of iron (III) chloride have a charge of 3+ and would bond with the -3 charged phosphate ions, creating a non-charged FePO4 molecule and removing the decomposition inhibitor from the solution. Potassium iodide and potassium chloride both are more strongly bonded than a transition metal compound and would lack the necessary charged iron ion when added to hydrogen peroxide.
Both in the phase of a liquid & has similar qualities like both molecules.
Hi, sorry this is late and you most likely no longer need it but the answer to this question is the Third one.. Boiling point.
Hopefully this helps somebody :)
D i hope it helps i not that smart
