A given mass of oxygen at room temperature occupies a volume of 500. 0 ml at 1. 50 atm pressure. what pressure must be applied t
andreev551 [17]

5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

<h3>Given</h3>

Mass of oxygen at room temperature =500.0 ml

Volume of pressure = 50 atm pressure.

The gas to a volume = 150.0 ml

<h3>Explanation</h3>

The volume decreases by the factor = 500.0 mL / 150.0 mL

                                                             = 10 / 3

The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to

P_{final} = \frac{10}{3} * 1.50 atm

          = 5.00 atm

So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

What is the role of pH in the maintenance of DNA inside a nucleus? How can pH be disrupted?
inysia [295]

Answer:

heyooooo!!!!!!

Hydrogen ions play a central role in the lives of cells. For example, changes in hydrogen ion concentration are intimately tied to the charge of side chains in proteins. This charge state, in turn, affects the activity of enzymes as well as their folding and even localization. Further, the famed ATP synthases that churn out the ATPs that power many cellular processes are driven by gradients in hydrogen ions across membranes.

hope this helps!!

Describe two ways polar bears are well adapted to surviving during the Arctic winter.
cricket20 [7]
They are well at surviving because of their thick white coat. The white fur helps them blend in with the snow and ice. The polar bear also has a layer of fat under their skin so they can survive harsh temperatures.
