A mineral contains only a metal, M, and sulfur. If analysis indicates that a 4.3 g sample of the mineral contains 1.56 g of M, w
1 answer:
Answer: 143.66 grams of M (g) is contained in 396 g of the mineral
Explanation:
Given : mineral contains metal M and sulphur
Mass of mineral = 4.3 g
Mass of metal M in mineral = 1.56 g
Thus if 4.3 gram of mineral contains metal = 1.56 g
Using unitary method for solving this :
1 g of mineral contains metal =
396 g of mineral contains metal =
Thus 143.66 grams of M (g) is contained in 396 g of the mineral

Answer : Electron P has greater energy difference than the Electron N.
Explanation :
Wavelength range of violet light = 400 - 500 nm
Wavelength range of orange light = 600 - 700 nm
The Planck's equation is,
where,
E = energy of light
c = speed of light
= wavelength of light
According to the Planck's equation, wavelength and energy follow inverse relation. As the wavelength increases, energy decreases.
From the given spectrum, the wavelength of violet light is less. We conclude that When electron P gives violet light on transition it means that energy difference between the energy level was high.
From the given spectrum, the wavelength of orange light is more. We conclude that When electron N gives orange light on transition it means that energy difference between the energy level was low.
So, Electron P which gives violet light on transition has greater energy difference than the Electron N.
