<u>Answer:</u>

option A is correct option.

Explanation :

A spontaneous method is capable of continuing during a given direction while not having to be driven by an outdoor supply of energy.

The laws of physical science govern the direction of a spontaneous method, guaranteeing that if a sufficiently sizable amount of individual interactions are concerned, then the direction can perpetually be within the direction of enhanced entropy.

Associate in Nursing endergonic reaction (also referred to as a nonspontaneous reaction) may be a chemical change during which the quality change in free energy is positive and energy is absorbed.

Endergonic processes will be pushed or force by coupling them to extremely exergonic reactions.

ΔG = ΔH - TΔS , ΔG is amendment within the free energy, ΔH is that the amendment in total heat, ΔS is that the amendment in entropy and T is temperature in kelvin.

Spontaneity of reaction Vs total heat Vs entropy

When ΔH is negative and ΔS is positive, ΔG are going to be negative over all temperatures.

When ΔH is negative and ΔS is negative, ΔG are going to be negative at low temperatures.

When ΔH is positive and ΔS is negative, ΔG won't be negative at any temperature. There would be no spontaneous reaction.

When ΔH is positive and ΔS is positive, ΔG are going to be negative at high temperatures.

Therefore, finally it's the amendment in free energy of a reaction which may predict if a reaction is possible.

Sidana [21]

Number of coulombs of positive charge in 250cm^3 water is 1.3×10^7 C

The volume of 250 cm^3 corresponds to a mass of 250 g since the density of water is 1.0 g/cm^3

This mass corresponds to 250/18 = 14 moles since the molar mass of water is 18. There are ten proton (each with charge q = +e) in each molecule of H_{2}O So,

Q = 14NA  q =14(6.02×10^23)(10)(1.60×10^−19C) = 1.3×10^7 C.

Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies.

How many electrons in the same atom can share the quantum number n = 2?
melisa1 [442]
With the principle quantum number being 2, the maximum number that can share this is 8. You can use the general formula 2n^2 to calculate this number (n=quantum level), or you can use the concept of quantum numbers (n, l, m, s) to justify this answer.

The electronic configuration of an atom of element X is 2,8,2 what will be the valency of the element x
KIM [24]

The element is Magnesium

  • It has total 12 electrons

it has electronic configuration

\\ \sf\longmapsto 2,8,2

or

\\ \sf\longmapsto 1s^22s^22p^63s^2

In valence cell it has 2 electrons and therefore its valency is 2
