Answer:

A positive and negative ion.

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.

Both bonded atoms have very large electronegativity difference.

The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Sodium have one valance electron while chlorine have 7 valance electrons. In order to complete the octet chlorine require one electron while sodium need to lose its one electrons. That's why when both atom combine sodium lose its electron and becomes positive ion i.e cation while chlorine accept its electron and becomes negative ion called anion and bond between them is ionic bond.

Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOx") that are of interest to atmospheric che

Helga [31]

Answer:

Partial pressure of dinitrogen tetroxide after equilibrium is reached the second time is 0.82 atm.

Explanation:

$2NO_2(g)\rightleftharpoons N_2O_4(g)$

Initially

3.0 atm 0

At equilibrium

(3.0-2p) p

Equilibrium partial pressure of $NO_2=2.1atm=3.0-2p$

p = 0.45 atm

The value of equilibrium constant wil be given by :

$K_p=\frac{p_{N_2O_4}}{(p_{NO_2})^2}=\frac{p}{(3.0-2p)^2}$

$K_p=\frac{0.45}{(2.1)^2}=0.10$

After addition of 1.5 atm of nitrogen dioxide gas equilibrium reestablishes it self :

$2NO_2(g)\rightleftharpoons N_2O_4(g)$

After adding 1.5 atm of $NO_2$ :

(2.1+1.5) atm 0.45 atm

At second equilibrium:'

(3.6-2P) (0.45+P)

The expression of equilibrium can be written as:

$K_p=\frac{p'_{N_2O_4}}{(p'_{NO_2})^2}$

$0.10=\frac{(0.45+P)}{(3.6-2P)^2}$

Solving for P:

P = 0.37 atm

Partial pressure of dinitrogen tetroxide after equilibrium is reached the second time:

= (0.45+P) atm = (0.45 + 0.37 )atm = 0.82 atm

Partial pressure of dinitrogen tetroxide after equilibrium is reached the second time is 0.82 atm.

When oxygen accepts electrons, water is produced as a byproduct. <br> a. True <br> b. False?

scZoUnD [109]

The answer is true. oxygen, the terminal electron acceptor, and water is formed as the product. pass through special proton channel proteins called ATP synthase. Arrange the following electron acceptors in the proper order in which they participate in electron transport. When oxygen accepts electrons, water is produced as a byproduct.

The solar corona has a temperature of more than a million kelvins; the photosphere has a temperature of only about 6000 K. Why i

kicyunya [14]

Answer & explanation:

Despite the huge difference in temperature between the solar corona and the photosphere, in addition to the fact that the solar corona is the largest and outermost layer of the solar atmosphere (about 13 million kilometers), the photosphere becomes a visible surface region due to to the gases present in it, causing the body to stop being transparent, becoming opaque to light.

However, it is still possible to observe the solar corona in total eclipses, where the opacity to light extends across the sun, facilitating the visibility of the corona and other layers.
