The total pressure of the mixture of gases is equal to the sum of the pressure of each gas as if it is alone in the container. The partial pressure of a component of the mixture is said to be equal to the product of the total pressure and the mole fraction of the component in the mixture.<span>

Partial pressure of hydrogen gas = 1.24 atm x .25 = 0.31 atm
<span>Partial pressure of the remaining = 1.24 atm x (1-.25) = 0.93 atm </span></span>

Answer:

0.31 atm

Explanation:

According to the Dalton's law of partial pressure, the total pressure of the gaseous mixture is equal to the sum of the pressure of the individual gases.

Also, the partial pressure of the gas is equal to the product of the mole fraction and total pressure.

Given, for hydrogen gas, it is 25% of the total moles.

So, Mole fraction = 0.25

Total pressure = 1.24 atm

<u>Partial pressure of hydrogen = 0.25 * 1.24 atm = 0.31 atm</u>

hat is the best way to compare a concentrated solution to a dilute solution, given the same volume of solution?
xxMikexx [17]

Answer:

Using the molarity of the solution

Explanation:

The concentration of the two solutions can be compared by the use of the number of moles of solute present in each of the solutions. The solution with a higher molarity will be concentrated while the solution with a lower molarity will be dilute.

Where are many foods imported from during our winter? Why can they grow food when we can't?
Mashutka [201]

It’s obvious to anyone who visits an American supermarket in winter — past displays brimming with Chilean grapes, Mexican berries and Vietnamese dragon fruit — that foreign farms supply much of our produce.

Imports have increased steadily for decades, but the extent of the change may be surprising: More than half of the fresh fruit and almost a third of the fresh vegetables Americans buy now come from other countries.

Although local, seasonal and farm-to-table are watchwords for many consumers, globalization has triumphed in the produce aisle. And despite the protectionist “America First” message coming from the Trump administration, the growth in imports appears likely to continue.

So this is an apt moment to examine how the shift happened, and what it portends — good or ill — for American consumers and farmers.

“I had no idea that more than half our fruit is imported, and it shocks me that this has happened so quickly,” said Michael Pollan, a professor of journalism at the University of California, Berkeley, whose best-selling books have analyzed the tensions between local and global food systems

A rigid container of gas has a pressure of 1.72 atm and temperature of 21 oC. If the temperature increases to 85 oC, what is the
Vinil7 [7]

Answer:

the new pressure is 2.09 atm

Explanation:

you have to use gay lussac's law so the formula is

p1/t1 = p2/t2

and convert C to Kelvin k=C+273.15

1.72atm/294.15 = p2/358.15

solve for p2 by multiplying 358.15 on both sides

p2=2.09 atm
