Answer:
Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don't move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.
<span>There's a trend in electronegativity. The bottom left of periodic table is the lowest (0.7) and the upper right is the highest (4.0). The most polar is the greatest difference in electronegavity.

Answer:
0.264 mol/L
Explanation:
Data obtained from the question includes:
Volume = 5.74L
Mass of FeCl3 = 246 g
Molarity =?
Next, we shall determine the number of mole in 246g of FeCl3.
This is illustrated below:
Mass of FeCl3 = 246g
Molar mass of FeCl3 = 56 + (35.5x3) = 162.5g/mol
Number of mole of FeCl3 =..?
Mole = Mass /Molar Mass
Number of mole of FeCl3 = 246/162.5
Number of mole of FeCl3 = 1.514 mol
Now, we can obtain the molarity of the solution as follow:
Molarity = mole /Volume
Volume = 5.74L
Mole of FeCl3 = 1.514 mol
Molarity = 1.514/5.74
Molarity = 0.264 mol/L
Partial pressure is the pressure that would be exerted by one of the gases in a mixture if it occupied the same volume on its own. For a mixture of gases, each gas has a partial pressure which is the hypothetical pressure of that gas if it alone occupied the volume of the mixture at the same temperature.
