For this system, we use Dalton's law of partial pressures where the total pressure of a gas mixture is said to be equal to the sum of the partial pressures of the gases. The partial pressure of each gas would be calculated by the product of the mole fraction and the original pressure of the gas. We do as follows:
Total pressure = x1P1 + x2P2
Total pressure = (2.0 / 7.0 )(3.5) + (1.5/7.0)(2.6)
Total pressure = 1.56 atm
Answer:
1- Option (A)
2- Option (A)
Explanation:
The pressure is often defined as the force per unit area. In the atmosphere, the pressure is maximum at the troposphere and is tightly packed near the ground surface. The troposphere is the region where the temperature decreases with the increasing height. The atmospheric pressure at sea level is nearly 1013.2 millibar (mb). The difference in the pressure in this layer causes the wind that is responsible for the occurrence of different types of weather patterns.
The earth and the sun maintains the shortest distance at its Perihelion position, which takes place in the month of January during the winter season in the northern hemisphere. And on the other hand, the earth is far away from the sun at its Aphelion position that takes place in the month of July.
Hence, the correct answers are given above.
The elements are identified by its aomic number and they are placed in the periodic table in ascending order of atomic number.
There is one unique element for a given atomic number.
For example, atomic number 1 identifies Hydrogen and there cannot be another different element with the same atomic number.
All the elements with atomic numbers from 1 to 118 have been discovered. So, you know that there is not room for new products with atomic number equal or less than 118.
Answer:By their movement, by their wastes, and by their metabolic.
Explanation:The nutrient cycle is a system where energy and matter are transferred between living organisms and non-living parts of the environment. This occurs as animals and plants consume nutrients found in soil, and these nutrients are then released back into the environment via death and decomposition.
