Is the following chemical equation balanced? kclo4 2kcl 2o2 yes no

No, the given chemical equation is not balanced.

Explanation:

A balanced chemical equation is defined as the equation in which number of atoms remains same on the reactant side as well as on the product side. The balanced chemical equation always follow Law of conservation of mass.

This law states that total mass on the reactant side is equal to the product side.

For the given equation,

Total mass on the reactant side =

Total mass on the product side =

As, the total mass on the reactant side is not equal to the total mass on the product side. Hence, the given equation does not follow Law of conservation of mass. Therefore, the given chemical equation is not balanced.

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.
