A mixture of He, Ne, and N2 gases has a pressure of 0,898 atm. If the pressures of He and Ne are 0.336 atm and 0.106 atm, respec
Alchen [17]

Answer:

Pressure for N₂ = 0.456 atm

Explanation:

There is law for gases which states that the sum of partial pressures of each gas in a mixture, is equal to the total pressure of the system.

For this case, we have a mixture of He, Ne and N₂

Then Total pressure is 0.898 atm

He's pressure + Ne's pressure + N₂'s pressure = 0.898 atm

N₂'s pressure = 0.898 atm - 0.336 atm - 0.106 atm

Pressure for N₂ = 0.456 atm

This is called the Dalton's law of partial pressures.

What is mean by saturated solution and unsaturated solution​
zvonat [6]

•Saturated Solution: A solution in which no more solute can be dissolved in a definite amount of solvent at a given temperature is called a saturated solution.

Example: A soda is a saturated solution of carbon dioxide in water. This is why, when the pressure is released, carbon dioxide gas forms bubbles.

•Unsaturated solution: It is a solution in which more of solute can be dissolved at a given temperature. In this, addition of solute is possible till the solution reaches the point of saturation.

Example: Salt dissolved in water even sugar dissolved in water is an Unsaturated solution if the quantity of dissolved Salt/Sugar is below the saturation point.

Which element would you expect to be more metallic?<br> (a) Ca or Rb (b) Mg or Ra (c) Br or I
svlad2 [7]

Explanation:

When we move across a period from left to right then there will occur an increase in electronegativity and also there will occur an increase in non-metallic character of the elements.

As calcium (Ca) is a group 2A element and rubidium (Rb) is a group 1A element. Hence, Rb being an alkali metal is more metallic in nature than calcium (alkaline earth metal).

Both magnesium (Mg) and radium (Ra) are group 2A elements. And, when we move down a group then as the size of element increases so, it becomes easy of the metal atom to lose an electron.

As a result, there occurs an increase in metallic character of the element. Hence, Radium (Ra) is more metallic in nature than magnesium (Mg).

Also, both bromine and iodine are group 17 elements. Since, both of them are non-metals and non-metallic character increases on moving down the group.

Therefore, bromine (Br) is more metallic than iodine.
