What type of bonding occurs in a sample of pure chromium, cr? in other words, how is one chromium atom held to another chromium
spayn [35]

Chromium is a metal in nature. So when one chromium is bonded to another chromium, there is a weak intermolecular forces which helds them together which we call as “metallic bonding”.

Metallic bonding is the intermolecular force of attraction which exist between valence electrons and the metal atoms. It is considered as the sharing of various detached electrons between many positive ions, whereby the electrons serve as a "glue" which gives the substance a definite structure.

Which net ionic equation best represents the reaction that occurs when an aqueous solution of barium chloride is mixed with an a
vovangra [49]

Answer : The net ionic equation will be:

Ba^{2+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced molecular equation will be,

BaCl_2(aq)+Li_2SO_4(aq)\rightarrow 2LiCl(aq)+BaSO_4(s)

The complete ionic equation in separated aqueous solution will be,

Ba^{2+}(aq)+2Cl^-(aq)+2Li^+(aq)+SO_4^{2-}(aq)\rightarrow 2Li^+(aq)+2Cl^-(aq)+BaSO_4(s)

In this equation the species, Li^+\text{ and }Cl^{-} are the spectator ions.

By removing the spectator ions , we get the net ionic equation.

The net ionic equation will be:

Ba^{2+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)
