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)

Using the equation above, how many moles of Na are produced when 2.75 moles of H2 react with excess NaCl? will give BRAINLIEST
almond37 [142]

Answer:

5.5 moles of sodium are produced

Explanation:

Given data:

Number of moles of hydrogen = 2.75 mol

Number of moles of Na produced = ?

Solution:

Chemical equation:

H₂ + 2NaCl      →       2HCl + 2Na

Now we will compare the moles of hydrogen and sodium from balance chemical equation:

                    H₂         :       Na

                     1          :       2

                   2.75      :       2/1×2.75 = 5.5 mol

Thus, 5.5 moles of sodium are produced.
