Benzene lacks a polar O-H bond, but ethanol does. Benzene C6H6 with ethanol C2H6O.
Benzene fails the iodoform test, whereas ethanol does.
While ethanol burns with a non-luminous flame, benzene produces a sooty flame.
Iodoform testing shows that ethanol passes whereas benzene does not.
In contrast to benzene, which generates a sooty flame, ethanol burns with a non-luminous flame.
Water does not mix with benzene, but organic solvents do.
It is a colorless liquid with a pleasant scent.
Benzene has a high melting point and a moderate boiling point.
It burns with a sooty flame and is quite flammable.
A clear, colorless liquid, ethanol has a distinct flavor of burning with a nice aroma. It has high flammability. Ethanol combines easily with water and a variety of organic liquids and is used to dissolve other chemical compounds.

When sodium carbonate decomposes, it also leaves behind carbon dioxide, or CO2. You can find this out without knowing about carbonate reactions though. Chemical equations must be balanced, so whatever is on the left must also be on the right. There are 2 atoms of sodium, one atom of carbon, and three atoms of oxygon on the left. On the right, there is two atoms of sodium and one atom of oxygen. We are still missing one atom of carbon and one two atoms of oxygen, which, when combined, make a molecule of carbon dioxide.
Explanation:
Sulfuric Acid (H2SO4) is a strong mineral acid that has is colorless when pure. This chemical is used as a chemical intermediate to manufacture other chemicals and cleaning metal surfaces. The formula for sulfuric acid is H2SO4. The molar mass of sulfuric acid is 98.07848 g mol.
<span>These are the rules of the quantum numbers that you have to use to dilucidate the validity of a set of quantum numbers:
</span><span />
<span>1) Main quantum number, n: 1, 2, 3, 4, 5, 6, 7
</span>
<span /><span /><span>
2) Second quantum number, ℓ: 0, 1, 2, ... n-1
</span><span />
<span>3) Third quantum number (magnetic quantum number), mℓ: -l,...0,,,,+l
</span><span />
<span>4) Fourth quantum number (spin): ms: +1/2 or -1/2
</span>
<span /><span /><span />
Answers:
<span>i) 3,2,0,1/2: valid, because 0<= l < n; - l <= ml <= +l; and ms = +1/2 or -1/2
</span>
<span /><span /><span>
</span><span>ii) 2,2,-1, 1/2 invalid because l = n (violates second rule)</span><span /><span>
</span><span>
</span><span>iii) 4,3,-4,1/2 invalid because ml is less than - l (violates third rule)</span><span /><span>
</span><span>
</span><span>iv) 1,0,0,1/2 valid: meet the four rules</span><span /><span>
</span><span>
</span><span>v) 2,2,1,-1/2 invalid because l = n (violate the second rule)</span><span /><span>
</span><span>
</span><span>vi) 3,2,1,1 invalid because ms can be only +1/2 or -1/2 (fourth rule)
</span>
<span /><span /><span>vii) 0,1,1,-1/2 invalid because l > n (violates rule 2)
</span>
<span /><span /><span>viii) 3,3,1,1/2 invalid because l = n (violate rule 2)
