The spontaneous intermingling of atoms among different substances is accomplished by _____.-molecular kinetic energy
-diffusion
-displacement
-condensation
Answers
Answer: The spontaneous intermingling of atoms among different substances is accomplished by diffusion.
Explanation:
Diffusion means to spread out. In diffusion, the molecules or atoms move from a region of high concentration to low concentration.
In other words, we can say that the spontaneous intermingling of atoms among different substances is accomplished by diffusion. Diffusion depends on the random walk of an atom or molecule.
Molecular kinetic energy is the energy of a gas at ordinary temperature in which the atoms or molecules are in rapid motion.
Displacement is the property in which a reactive element displaces less reactive element from its position.
Condensation is the process of changing water vapor into liquid.
Thus, it can be concluded that the spontaneous intermingling of atoms among different substances is accomplished by diffusion.

Answer: The balloon will not survive.
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 1 atm
= final pressure of gas = 0.05 atm
= initial volume of gas = 4.0 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
As the balloon has the capacity to expand to a 50 liter volume before bursting, it can not survive as it occupies volume higher than 50 L

Answer;
From highest to lowest is Li>Na>K>Rb.
Explanation;
- Ionization energy is the energy that is required to dislodge or remove an electron from the outer most energy level or energy shell. The first ionization energy is the energy required to remove the first electrons from the outermost energy shell.
- Lithium will have the highest first ionization energy, as the outer electron is closer to the pull of the nucleus and not shielded by full shells. This means that rubidium will be the lowest.

the hydrogen end
Answers
Answer:
the hydrogen end
Explanation:
In H - F molecules there is a charge separation. Hydrogen has partial positive charge on them and Fluorine has a partial negative charge on it.
- The bonds between H - F molecule is a covalent bond.
- In this bond, both atoms share their electrons to attain a stable configuration
- But the electrons are not shared equally.
- Fluorine is more electronegative compared to the hydrogen.
- Fluorine therefore, attracts the shared electrons more closely to itself.
- This makes fluorine more negative and hydrogen positive.
