Metals like sodium, potassium, magnesium, etc. are extracted by electrolysis of their chlorides in molten state.

These metals are not extracted by reduction of their oxides with carbon because:

Carbon has less affinity for oxygen than these metals

Carbon is a weaker reducing agent than these metals

These metals easily form oxides with oxygen, their oxides are very stable. Affinity to the oxygen is one the greatest of all elements.

Reducing agent is element or compound who loose electrons in chemical reaction. Sodium, potassium, calcium and magnesium are very strong reducing agents because they easily loose one or two valence electrons.

Electrolysis is a chemical methode that uses electric currents for chemical reactions.

Answer:

covalent bonds

Explanation:

ionic transfer of e^- ions formed (charges)

ionic=non-metal+ metal

ex: F+Ca

covalent sharing e^- no true charges

covalent= non-metal+ non-metal

ex: F+P

C10H22 &gt; C8H18+C2H4 if only ethane can be sold what is the atom econmy of this process
insens350 [35]

Answer:

The atom economy of ethane in this process is 19.72 %.

What is atom economy?

The conversion efficiency of a chemical reaction in terms of all the atoms involved and the desired products produced is known as atom economy (atom efficiency/percentage).

Explanation:

C₁₀H₂₂ → C₈H₁₈ + C₂H₄

Molecular weight of C₁₀H₂₂ = 142.28

Molecular weight of C₈H₁₈ = 114.228
Molecular weight of C₂H₄ = 28.053

% Atom economy =     \frac {Molecular weight of C2H4} {Molecular weight of C10H22}

                             = \frac{28.053}{142.28}*100

                             = 19.716 %

                             ≈ 19.72 %
