A 187.4g sample of C3H5(NO3)3 decomposes to produce carbon dioxide, water, diatomic oxygen, and diatomic nitrogen.
Radda [10]

Answer:

Answer:

Kc = 0.20        

Explanation:

                 N₂O₄     ⇄    2NO₂

moles       5.3mol          2.3mol

Vol               5L                5L

Molarity    5.3/5M        2.3/5M

               = 1.06M     = 0.46M

Kc = [NO₂]²/[N₂O₄] =  (0.46)²/(1.06) = 0.1996 ≅ 0.20

Note:

All credit goes to  <em>drpelezo </em>(Ace) who created and explained the answer.

Have a nice day, and I hope this helps

Which substance would have the highest melting point, based on electronegativity?
kenny6666 [7]

Water, H₂O, will have the highest melting point.

Explanation:

So here we have listed the hydrides of oxygen, sulphur, selenium and tellurium.

From this elements oxygen have the highest electronegativity and as a consequence the oxigen hydride (water, hydrogen dioxide) it is able to form hydrogen bonds between molecules. So you need more energy to overcome the interactions between molecules in water that for the other compounds.

Water, H₂O, will have the highest melting point between the listed hydrides.

You are given two closed containers. Each containing a liquid solvent. Ammonia and table salt will dissolve in container A. Hexa
snow_tiger [21]
Ammonia and table salt dissolves in polar solvents, so A is water,
CO2 and hexane are non-polar substances, so they are going to be dissolved in non-polar solvent, so I think it is going to be carbon tetrachloride

Answer is <span>A) A - water; B - carbon tetrachloride

Table salt does not dissolve in oil and CCl4, and Br2 is too active and it is going to react with NH3.</span>
