Answer:
3.87 mol N
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
Explanation:
<u>Step 1: Define</u>
54.2 g N
<u>Step 2: Identify Conversions</u>
Molar Mass of N - 14.01 g/mol
<u>Step 3: Convert</u>
<u /> = 3.86867 mol N
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
3.86867 mol N ≈ 3.87 mol N
Explanation:
option A:
is an anion and
is also an anion.So,there is no reaction.
option B:
reacts with
to form
.
Since is a first group element,all its salts are soluble in water.
Hence no precipitate is formed.
option C:
reacts with
to form
.
Since is a first group element,all its salts are soluble in water.
Hence no precipitate is formed.
option D:
reacts with
to form
.
Solubility of sulphates of second group elements decrease down the group.
So, is a precipitate.

Answer:
The melting of the caps increases the concentration of CO2 in the water, making its absorption faster.

Explanation:
<h2><u>CO2 absorption</u><u> </u></h2>The polar caps of our planet have in their composition several elements, among them the CO2 that is absorbed by the atmosphere. Cold waters, which are present in the Arctic, have an easier time absorbing CO2 compared to other waters.
When glaciers melt, the CO2 that is present in the mixture is dissolved in the ocean, increasing its concentration. The cold waters that came from the ice caps increase the absorption of CO2.
