<u>Answer:</u> The beta-particle is being released in the reaction and the nucleus is changing from to nitrogen.
<u>Explanation:</u>
Carbon-14 undergoes a radioactive decay by the process of beta-minus decay.
In beta-minus decay, a neutron gets converted to a proton and an electron.
The equation for the beta-minus decay of carbon-14 follows the reaction:
In this reaction beta-particle is being released carrying -1 charge. Another name for this particle is known as electron.
In this decay process, the nucleus is changing from carbon to nitrogen. The property of the nucleus is changing completely as number of protons is getting increased.
<span>The
list of phases of H2O that is arranged in order of increasing entropy is from
solid then liquid then gas. Gaseous water has the most entropy because of the
random movement of water molecules. And Solid having the least entropy because the
water molecules are arranged in a specific order.</span>
Answer:
Option C.
Explanation:
The arrangement of electrons in their orbital follows certain rules.
The Hund's rule practically explained how electrons are distributed in their orbitals.
The Hund's rule states that electrons distributed among the orbitals of the same shell singly (without partner) before pairing occurs.
In the filling of these electrons in their orbitals, we fill in the electron without pairing first because electrons tends to repel each other before filling with the opposite spin as shown in the attached photo.
Answer:
water, host
Explanation:
Clathrate hydrates are the crystalline water-based solids which physically resembles with the ice, in which the small non-polar molecules or smaller polar molecules with the large hydrophobic moieties are usually trapped inside the "cages" of the hydrogen bonded as well as frozen water molecules.
<u>Clathrate hydrates are the clathrate compounds in which water creates the cage and the water behaves as a host molecule and guest molecule is typically a gas or liquid.</u>
Benzene
- Benzene has low density than the water itself of about 0.9 g/cm³
Low denisty object than the water usually <u>floats on the water</u>.
Another example: orange peel which floats on water has density of about 0.84 g/cm³
