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
Nitrogen oxides help cause some kinds of air pollution. Nitrogen dioxide combines with other chemicals to make smog. It also combines with water droplets in the air to make nitric acid. Nitric acid is one of the kinds of acid in acid rain. Volcanoes and lightning make some of the nitrogen oxides in Earth's atmosphere. Humans make lots of nitrogen oxides, too. When fuel burns, nitrogen in the air combines with oxygen to make nitrogen oxides. The engines of cars, trucks, and buses make lots of nitrogen oxides. Nitrogen oxides are not all bad. Humans use nitric oxide to make nitric acid. Nitric acid is used to make fertilizer and some kinds of explosives.
The combination of decay processes that would convert U-239 into PU- 239 is beta decay followed by another beta decay. Beta decay involves the emission of an electron [positron]. There are two types of beta decay; positive and negative beta decays and both occur simultaneously in order to move the atoms towards stability.
The number of different bond angles is 6 and here you have the different angles:
Br(ax)-P-Br(eq) ..... greater than 90 degrees (axial to equatorial)
<span>Br(eq)-P-F(ax) ...... greater than 90 degrees (equatorial to axial) </span>
<span>Br(ax)-P-F(eq) ...... less than 90 degrees (axial to equatorial) </span>
<span>F(ax)-P-F(eq) ........ less than 90 degrees (axial to equatorial) </span>
<span>F(eq)-P-F(eq) ........ less than 120 degree (equatorial) </span>
<span>Br(eq)-P-F(eq) ...... greater than 120 degrees (equatorial) </span>
