Answer:
The total pressure of the mixture is 5, 53 atm.
Explanation:
The sum of the partial pressures of the gases that make up a gaseous mixture is equal to the total pressure of said mixture, according to Dalton's law. We convert the unit of pressure in mmHg into atm:
760 mmHg----1 atm
785 mmHg----x= (785 mmHgx 1 atm)/760 mmHg=1, 03 atm
P total= P 02 + P N2
P total= 4, 5 atm + 1,03 atm=<em>5, 53 atm</em>
Answer:
Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another. This transported material is called sediment.
