Answer:

Mafic minerals contain more dark-colored, high-density minerals.

Explanation:

Mefic and felsic minerals represent two kinds of minerals or lava.

For example, mefic lava is more viscous than felsic lava.

The other difference is that word mafic is related to presence of Magnesium and iron minerals more while in felsic (Feldspar) silica content is more.

Mefic minerals are associated with dark color while felsic are lighter in color.

A mixture of H2 and water vapor is present in a closed vessel at 20. 00°C. The total pressure of the system is 755. 0 mmHg. The
MAVERICK [17]

The partial stress of H2 is 737.47 mmHg Let's observe the Ideal Gas Law to find out the whole mols.

We count on that the closed vessel has 1L of volume

  • P.V=n.R.T
  • We must convert mmHg to atm. 760 mmHg.
  • 1 atm
  • 755 mmHg (755/760) = 0.993 atm
  • 0.993 m.1L=n.0.082 L.atm/mol.K .
  • 293 K(0.993 atm 1.1L)/(0.082mol.K /L.atm).
  • 293K = n
  • 0.0413mols = n

These are the whole moles. Now we are able to know the moles of water vapor, to discover the molar fraction of it.

  1. P.V=n.R.T
  2. 760 mmHg. 1 atm
  3. 17.5 mmHg (17.5 mmHg / 760 mmHg)=0.0230 atm
  4. 0.0230 m.1L=n.0.082 L.atm/mol.K.293 K(0.0230atm.1L)/(0.082mol.K/L.atm .293K)=n 9.58 × 10 ^ 4 mols = n.
  5. Molar fraction = mols )f gas/general mols.
  6. Molar fraction water vapor =9.58×10^ -four mols / 0.0413 mols
  7. Sum of molar fraction =1
  8. 1 - 9.58 × 10 ^ 4 × mols / 0.0413 ×mols = molar fraction H2
  9. 0.9767 = molar fraction H2
  10. H2 pressure / Total pressure =molar fraction H2
  11. H2 pressure / 55mmHg = =0.9767 0.9767 = h2 pressure =755 mmHg.
  12. 737,47 mmHg.
<h3>What is a mole fraction?</h3>

Mole fraction is a unit of concentration, described to be identical to the variety of moles of an issue divided through the whole variety of moles of a solution. Because it's miles a ratio, mole fraction is a unitless expression.

Thus it is clear that the partial pressure of H2 is 737,47 mmHg.
