The minimum volume of 0.2M sodium sulfide that will precipitate out aluminum from 50.0 mL, 0.25 M aluminum nitrate would be 0.094 L or 94 mL
<h3>Stoichiometric calculation</h3>
From the equation of the reaction:
Mole ratio of Na2S and Al(NO3)3 = 3:2
Mole of 50.0 mL, 0.25 M Al(NO3)3 = 50/1000 x 0.25
= 0.0125 mole
Equivalent mole of Na2S = 3/2 x 0.0125
= 0.0188 mole
Volume of 0.2M, 0.0188 mole Na2S = 0.0188/0.2
= 0.094 L or 94 mL

<span>FIXATION.In the nitrogen cycle, nitrogen is converted into many chemical forms through biological and physical processes like nitrogen fixation, ammonification, nitrification and denitrification.During ammonification, ammonium ions are released after decomposition of plants.During nitrogen fixation, nitrogen gas is changed to nitrates by nitrogen fixing bacteria in the soil.These are used by vegetation.</span>
Hurricanes always originate over oceans. The correct answer is choice C.
<span>An atom is the most basic form
of life. Also, an atom can represent an element. The element can be different
such as oxygen, nitrogen, everything that is present in the periodic table. We
can also classify an element into a metal, nonmetal or metalloid. The very core
of an atom is the nuclei. Protons and neutrons are present inside the nuclei. A combination of elements is a compound. When formed,
they can be very stable. The answer is D.</span>
