Answer:
Explanation:
Anything oxide is a compound with oxygen, and since oxygen is -2, it requires two of the metal's +1 to make it zero
In other words:
2(+1) + (-1) = 0

B. 100 meters is only equal to 1 hectometer.
According to
Graham's Law of Diffusion,"the rates of diffusion of two gases are inversely proportional to the square root of their Molar masses or Densities at the same pressure and temperature".
r₁ / r₂ =
Where,
r₁ = Rate of Fluorine
r₂ = Rate of Bromine
M₂ = Molar mass of Bromine = 159.8 g/mol
M₁ = Molar mass of Fluorine = 37.98 g/mol
Putting values,
r₁ / r₂ =
r₁ / r₂ =
r₁ / r₂ =
2.04Result: Fluorine effuses
2 times faster than Bromine gas.
Answer the correct answer out of the four is option c spectroscopy
Explanation- The interaction between electromagnetic radiation and matter studied. This study is commonly known as spectroscopy. It can also be named as study of absorption spectra or emission spectra.
The former spectrum is formed when energy is absorbed from Photons or light energy by electrons while the latter spectrum is formed due to a wavelength of light that is released when electrons jump from higher to lower level.
