Consider two different ions. The anion has a valence of -2. The cation has a valence of +2. The two ions are separated by a dist

ance of 1 nm. Please calculate the force of attraction between the anion and cation. The force of attraction is given by: (9 x 109 V/C) (Z)(2)(e2) FA valence of the ions, e = charge of an electron 1.602 x 10-19 C Where Z1 and Z2 r distance between ions 1N 1 (V C/m)

Answer:

Force of attraction = 35.96 \times 10^{27}N

Explanation:

Given: charge on anion = -2

Charge on cation = +2

Distance = 1 nm = 10^{-9} m

To calculate: Force of attraction.

Solution: The force of attraction is calculated by using equation,

F = \dfrac{k \times q_1 q_2}{ \r^2} ---(1)

where, q represents the charge and the subscripts 1 and 2 represents cation and anion.

k = 8.99 \times 10^9 \ Nm^{2}C^{-2}

F = force of attraction

r = distance between ions.

Substituting all the values in the equation (1) the equation becomes

F = \dfrac{8.99 \times 10^9 \times 2 \times 2}{ \left ( 10^-9 \right )^2 }

Force of attraction = 35.96 \times 10^{27}N

What is the relationship between temperature and volume?
Lelu [443]

Answer:

Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant

The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles's law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law)

|||Good points and Brainliest||| Explain the biological pump <br> (have at least 3 sentences pls)
Ber [7]

Answer:

The biological pump or the marine carbon pump is the title for multiple processes leading to separation of carbon from multiple sources of water. Biological pumping is partially responsible for the cycling of organic matter. This process can lead to loss of contact between carbon and the atmosphere for thousands of years.
