Answer:
Partial pressure O₂ = 1.78 atm
Explanation:
We can apply the mole fraction to solve the question:
Moles of gas / Total moles = Partial pressure of gas / Total pressure
Total moles = 1 H₂ + 2.5 He + 2O₂ = 4.5 moles
2 mol O₂ / 4.5 mol = Partial pressure O₂ / 4 atm
(2 mol O₂ / 4.5 mol ) . 4 atm = Partial pressure O₂ → 1.78 atm
Answer:
The generation of a magnetic field by an electric current is called electromagnetism.
Explanation:
Explanation:
Because the salt is a charged, ionic compound, whereas the parent is purely covalently bounded, therefore, the salt of an organic acid or base is much more water soluble than the parent acid or base.
This is important because water molecules can "dissolve" a charged molecule, which means that it can be surrounded and stabilized by water molecules.
In contrast, water molecules are not drawn to parent acid or base nonpolar substituents, and the molecule's total polarity is determined by the relative electronegativity of the polar group and molecule surface area.
In other words, a long chained molecule in water are usually insoluble whereas a short chain is likely to be soluble.

Answer:
The pressure from the weight of the glacier generates a layer of water that helps the ice glacier move downslope. This process is called basal sliding. Also, the glacier begins to move under its own weight. The glacier is so heavy and exerts so much pressure that the firn and snow melt without any increase in temperature.
