a gas mixture is exerting a pressure of 1.04 atm inside a sealed container. The gas was found to be a mixture of carbon dioxide and nitrogen gas. If the mixture is 42% CO2, what is the partial pressure of nitrogen

Partial pressure of Nitrogen = 0.6032 atm

Explanation:

According to Dalton's law of partial pressure, at constant temperature, the total pressure exerted by a mixture of gases that do not react with one another is a sum of the partial pressures of the individual gases. And the partial pressure of each gas is proportional to their percentage composition. The partial pressure of each as is given as

Partial Pressure = (Percentage composition) × (Total pressure)

In this question, a gas mixture of Carbon dioxide and Nitrogen exerts a total pressure of 1.04 atm

The mixture contains 42% CO₂, meaning it contains 100-42 = 58% of Nitrogen.

Partial Pressure of Nitrogen = 0.58 × 1.04 = 0.6032 atm

Hope this Helps!!!

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

explanation:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
