Answer:
Nitrogen emissions such as ammonia, nitrogen oxide and nitrous oxides contribute to particulate matter and acid rain. Nitrous oxide is a particularly potent greenhouse gas as it is over 300 times more effective at trapping heat in the atmosphere than carbon dioxide.
Explanation:
These atoms are bonding to increase their stability and decrease their energy levels by bonding into electron configurations that follow the Octet Rule. The Octet Rule relates to atoms wanting to have 8 valence electrons in their outer-most electron shell. Noble gases are the only elements to already have 8 valence electrons before bonding. For this reason, Noble gases are usually already stable low energy atoms that are less likely to form bonds than all the other elements on the periodic table.
Answer: This is called fulfilling the Octet Rule.

Answer:
Percent yield = 94.62%
Explanation:
Given data:
Actual yield of BeBr₂ = 1.23 mol
Theoretical yield of BeBr₂ = 220 g
Percent yield = ?
Solution:
Theoretical yield in moles:
Number of moles = mass/molar mass
Number of moles = 220 g/168.82 g/mol
Number of moles = 1.30 mol
Percent yield:
Percent tiled = actual yield / theoretical yield × 100
by putting values,
Percent yield = 1.23 mol / 1.30 mol × 100
Percent yield = 0.9462 × 100
Percent yield = 94.62%
The molality of the lithium ions is calculated as 0.906 m
<h3>What is the molality of lithium ions?</h3>
Given that the compound is written as Li₃PO₄, the dissociation of the compound is given by the equation;
Li₃PO₄ -----> 3Li^+ + PO₄^3-
Since there are three mole of lithium ions in the compound, it the follows that the molality of the lithium ions is;
3 * 0.302 m = 0.906 m
