If molten sodium chloride is split by electrolysis, which reaction occurs at the anode?

mariarad [96]

Answer: $2Cl^-(l)\rightarrow 2e^-+Cl_2(g)$

Explanation:

Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.

In the electrolysis of molten sodium chloride, sodium metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.

$2NaCl(l)\rightarrow 2Na^++2Cl^-$

At anode : $2Cl^-(l)\rightarrow 2e^-+Cl_2(g)$

At cathode : $2Na^+(l)+2e^-\rightarrow 2Na(l)$

The density of water at 400C is 0.992 g/mL What is the volume of 27.0 g of water at this temperature?

pantera1 [17]

Answer:

Volume of water at this temperature is 27.2 mL

Explanation:

We know that $density=\frac{mass}{volume}$

Here density of water is 0.992 g/mL

Here mass of water is 27.0 g

So $volume=\frac{mass}{density}$

= $\frac{27.0g}{0.992g/mL}$

= 27.2 mL
