Answer:
Thermosphere
Explanation:
More specifically the ionosphere, since the ionosphere is the lower part of the thermosphere.
Hope this helps!
Answer:
First, the number of ammonium sulfide molecules should be calculated:
N = NA × n,
where NA - the Avogadro number, n - number of moles.
N (ammonium sulfide) = 6.022 × 1023 × 8.5 mol = 51.187 × 1023.
The moelcular formula of ammonium sulfide is (NH4)2S. It means that each molecule contains 8 hydrogen atoms.
As a result, 8.5 mol of (NH4)2S contain:
51.187 × 1023 × 8 = 41 × 1024 hydrogen atoms.
Answer: 41 × 1024 hydrogen atoms
Answer : Option C) Non metal.
Explanation : A non metal is the one which does has poor thermal conductivity, poor electrical conductivity, are usually brittle solids which are not malleable or ductile, they have little or no metallic luster at all, and they gain electrons easily.
These are the properties which are seen in a non metal.
Answer:
The correct answer is "two".
Explanation:
The main bondings that has an effect in a Lewis structure in NO2Cl are the double bondings occurring between the Oxygen atoms and the Nitrogen atom. Since the NO2Cl compound has two oxygen atoms attached to the nitrogen atom, two equivalent lewis structures will be necessary to describe it. I attached an example of two equivalent Lewis structure corresponding to a NO2 molecule.
