Explain how metallic bonding causes metals to conduct electricity?

1 answer:

3 0

In a metallic bond, atoms of the metal are surrounded by a constantly moving "sea of electrons". This moving sea of electrons enables the metal to conduct electricity and move freely among the ions.

If 1.0 M HIM HI is placed into a closed container and the reaction is allowed to reach equilibrium at 25∘C∘C, what is the equili

sattari [20]

The given question is incomplete. The complete question is

If 1.0 M HI is placed into a closed container and the reaction is allowed to reach equilibrium at 25∘C∘C, what is the equilibrium concentration of H2 (g). Given the equilibrium constant is 62.

Answer: The equilibrium concentration of $H_2$ is 0.498 M

Explanation:

Initial concentration of $HI$ = 1.0 M

The given balanced equilibrium reaction is,

$2HI(g)\rightarrow H_2(g)+I_2(g)$

initial (1.0) M 0 0

At eqm (1.0-2x) M (x) M (x) M

The expression for equilibrium constant for this reaction will be,

$K_c=\frac{[H_2]\times [I_2]}{[HI]^2}$

Now put all the given values in this expression, we get :

$62=\frac{(x)^2}{1.0-2x}$

By solving we get :

$x=0.498M$

Thus the equilibrium concentration of $H_2$ is 0.498 M

Why do non-metal aroms form covalent bonds e.g. H2O

Oksana_A [137]

Answer:

Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. ... Covalent compounds tend to be soft, and have relatively low melting and boiling points.
