<h2>Answer:</h2>

The entropy decreases in <u>B. a gas condensing</u>.

<h2>Explanation:</h2>

Entropy refers to phenomenon which measures the spreading of energy in a system. The energy of the system is spreading it has high entropy, whereas if the energy of the system remains concentrated it is said to have decreased entropy.

In case of air escaping from the tire the energy is spreading out that's why the air is moving out of the tire. Thus, it has high entropy. In case of gas condensing which leads to the formation of liquid, the energy of the gaseous particles remains concentrated such that it may lead to the formation of liquid. Thus, this system has decreased entropy.

If you can answer as many of these as possible that would be great, will give thanks, 5 stars, and brainliest :)

Answer:

The nucleus of the atom as suggested by "nuclear" chemistry.
Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons.
An excessive amount of protons or neutrons.
Periodic table, table O, and table N.
Personal opinion question.
The atomic number.
It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge).
Protons ---- element.
Random, self-generated.
Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass.
Neutrons and Gamma radiation.
Gamma radiation.
Electrons and Beta particles.
To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element.
The number of protons because they are what define the identity of an element.

Goodluck!

Ivenika [448]

Answer:

a. in supernovae and star collisions

Explanation:

The periodical table contains some heavier elements, which are formed as neutron stars pairs hit eachother and erupt cataclysmically.

The star emitts very large quantities of energy and neutrons during supernova, which allow for the production of heavier elements than iron, such as uranium and gold. All these elements are ejected into space during the supernova explosion.
