Answer: It’s producing 75% of it’s potential.

Example: If I were to be playing basketbal, and my body was working at 75%, then there is 25% of energy that I’m not using, making me worse than if I was using 100%.

Choose the pair of substances that are most likely to form a homogeneous solution.

oksano4ka [1.4K]

Answer is: a. c6h14 and c10h20.
This pair will most likely form a homogeneous solution because they are both nonpolar substances and "like dissolves like".
Other pairs will not form homogeneous solution because nonpolar substances have low solubility in polar or ionic substances (for example LiBr is ionic and C₅H₁₂ is nonpolar).

The partial pressure of N2 in a mixture of gases, where the total pressure is 1.50 atm, is 300. torr. What is the mole fraction

makvit [3.9K]

Answer:

The mole fraction of N₂ is 0.26.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

PT = PA + PB

This relationship is due to the assumption that there are no attractive forces between the gases.

Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture. The mole fraction is a dimensionless quantity that expresses the ratio of the number of moles of a component to the number of moles of all the components present.

So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:

PA = XA * PT

In this case:
