Answer:

<em><u>universal law of </u></em><em><u>gravitation</u></em>

Explanation:

According to Newton's law of gravitation, every particle in universe attracts every other particles with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between their centres!

Consider two particles having masses m1 and m2 and are apart r units, then the gravitational force acting between them is given by

F = G \cdot \frac{m1\cdot \: m2}{ {r}^{2} }

Where G is universal gravitational constant or proportionality constant!!

List the subshells that hold the 25 electrons in a<br> manganese atom in order of increasing energy
jonny [76]

Answer:

1s2 2s2 2p6 3s2 3p6 4s2 3d5

Explanation:

According to the Aufbau principle, electrons are filled in orbitals in order of increasing energy. The energy of orbitals in the electronic configuration of manganese increases from left to right, hence 3d orbital is much greater in energy than a 3p orbital.

The arrangement of orbitals in order of increasing energy is shown in the answer above.

The overall reaction of ozone reacting to form oxygen has been proposed to occur in a reaction mechanism of: What is the role of
LekaFEV [45]

Answer:

3) O(g) is an intermediate; 2O3(g)→3O2(g)

Explanation:

The decomposition of ozone to yield oxygen occurs in a sequence of steps. The various non-elementary reactions involved constitute the reaction mechanism. In the sequence of reaction steps O(g) serves as an intermediate.

The overall reaction involves the conversion of two moles of ozone to three moles of oxygen as shown in the answer. Thus the O(g) is merely a reaction intermediate.

Which type of reaction occurs in the following equation?
aniked [119]

Answer:

The right choice is → a reduction reaction

Explanation:

From the balanced equation

  • 3CIO⁻₍aq₎ → CIO⁻ ₍aq₎ + 2Cl⁻ ₍aq₎

we can calculate the change in oxidation number of Cl in reactant and product

in reactant ClO⁻

let x= oxidation number of Cl

and oxidation number of oxygen in its compound is (-2)

and the total charge on the ClO⁻ ion = -1

  • ∴x + (-2) = -1 →→→ x = +1

in product Cl⁻

let x= oxidation number of Cl

and the total charge on the Cl⁻ ion = -1

  • ∴x = -1

so the oxidation number of Cl decreases from +1 in reactant to -1 in product so it is reduction reaction.

But, disproportionation reaction is defined as the chemical reaction in which a single substance gets reduced as well as oxidized.

For a disproportionated substance  , it should contain at least three oxidation states. which isn't the case here.

<u>So, the right choice is: </u>

→ a reduction reaction
