Then as the electrons in the atoms fall back down, they emit electromagnetic radiation (light). The amount of light emitted at different wavelengths, called the emission spectrum, is shown for a discharge tube filled with hydrogen gas in Figure 12.6 below.
Answer:
The molar mass and atomic mass are essentially the same for an element
Explanation:
The molar mass of a substance can be obtained by dividing the mass of the substance by the no of moles of the substance present.
The atomic mass of an element is the number of protons and neutrons present in the substance.
These two measurements usually give the same values because they both make reference to the 1/12th the mass of carbon-12 for their measurement.
Because they both have the same reference point, though they have different calculating procedures, the results obtained will be similar.
Answer:
A: rift
Explanation:
Divergent boundaries within continents initially produce rifts, which produce rift valleys.
Answer:
i=1.62 .
Explanation:
Let, i be the Van't Hoff Factor.
Moles of benzamide,=
Molality of solution, m=
Now, we know
Depression in freezing point, 
.....1
It is given that,
Putting all these values we get,
Now, moles of ammonium chloride=
molality =
Putting all these values in eqn 1.
We get,
i=1.62 .
Hence, this is the required solution.
