A classmate has balanced the following reaction. Explain why their equation is not correctly balanced, and tell the correct way to balance the equation.
6 LiBr + 2 Fe_3(PO_4)_2 = 2 Li_3PO_4 + 3 FeBr_2

See below

Explanation:

Coefficient on Fe₃(PO₄)₂ is incorrect => such means sum of mass reactants does not equal sum mass of products. Violates Law of Conservation of Matter in chemical reactions.

Correct balance is ...

6LiBr + Fe₃(PO₄)₂ => 2Li₃PO₄ + 3FeBr₂

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

wher is the rest of the question
