Technetium, with atomic number denoted Z43, is the lowest-numbered element in the periodic table of which all isotopes are radioactive
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:
Option O = H₂O
Explanation:
Chemical reaction:
2K + 2H₂O → 2KOH + H₂
In this balanced chemical equation we can see that water is the only compound that consist of two hydrogen atom and one oxygen atom. H : O
2 : 1 .
In case of KOH two hydroxyl and two potassium atom are present and ration is K:OH 1:1.
