Answer:
-272.604 °C
Explanation:
The metals can conduct electricity, but this conduction has some resistance, and there're dissipations in the energy during the conduction. Some material has the ability, at very low temperatures, to conduce electricity without the resistance. This ability is called superconducting.
The mK corresponds to the miliKevin, and 1 K = 1000 mK, thus, the temperature in Kevin is 0.546 K.
T(K) = T(°C) + 273.15
T(°C) = T(K) - 273.15
T(°C) = 0.546 - 273.15
T(°C) = -272.604 °C
Answer:
In nature the atoms of noble gases do not bond either with other gases or with each other. Helium exists as atoms of Helium not as diatomic molecules. Some of the larger noble gases can be made to form molecules. This does not normally happen in natural conditions.
Explanation:Noble gases are odorless, colorless, nonflammable, and monotonic gases that have low chemical reactivity. The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons.
Answer:
Another name of activation energy is "Needed energy" .
Explanation:
Activation energy can be imagined of as the measurement of the potential barrier (seldom described the energy barrier) distributing minima of the potential energy surface concerning the initial and ultimate thermodynamic phase. For a chemical reaction or distribution to advance at a reasonable rate, the specific temperature of the operation should be high satisfactory so that there subsists an apparent number of particles with translational energy equivalent to or higher than the activation energy. The word Activation Energy was founded in 1889 by the Swedish expert Svante Arrhenius.
Magnesium is a metal found in grp 2 and oxygen is a nonmetal foumd in grp 6.
A nonmetal and metal form ionic bond. Thus, the bond between Magnesium and oxygen is ionic.
