What is the pressure (in Pascals) of a sample of nitrogen that is at 625 mmHg?

Liquid nitrogen is cold and can be used to cool objects to -196°C. If you put the bottle of warm air in liquid nitrogen at this

vampirchik [111]

Answer:

Explanation:

It depends on how this is done. If you raise the pressure, the nitrogen will disappear (liquify) and all that will be left will be the 21 % oxygen and the 1% argon.

The process is very complicated because the boiling point of nitrogen keeps on changing. The boiling point is unstable.

The buildup of sediment where a river empties into a slow-moving or nonmoving body of water is known as a/an

777dan777 [17]

The buildup of sediment in which a river empties right into a slow-transferring or non transferring frame of water is referred to as a Delta.

<h3>What is Delta ?</h3>

Deltas are wetlands that shape as rivers empty their water and sediment into some other frame of water, together with an ocean, lake, or some other river.

A form of soil made nearly completely of windblown sediment is referred to as Loess.

The natural count number in soil comes from decaying flora and animals and their waste products.

Clay, that's made of tiny debris and drains water very poorly, is one of the essential additives of soil.

A form of soil referred to as peat is maximum probably to shape in a/an Coastal surroundings in Tropical placing.

Water enables withinside the improvement of soil with the aid of using carrying Mineral and vitamins from higher layers to decrease layers.

The Richness of nutrients from soil is not unusualplace in moist environments, like rain forests.

Quartz-wealthy determine cloth results in the improvement of Sandy soils.

The layers of soil composed specifically of natural count number are referred to as the O and A horizon.

A layer of soil wherein clay, iron, and different factors from the overlying soil accumulates is referred to as the B horizon, or subsoil.

Delta is stated to be a frame of sediments deposited whilst a river flows into a status water, together with the ocean or a lake.

Loess are wind blown deposits of silts and clay composed of quartz, feldspar and different minerals . Loess dominantly have excessive porosity.

Organic subjects compose specifically of stays of animal and flora . After this flora and animals dies they shape natural count number that provides to soil vitamins.

Clayey soil represent very tiny debris which have a bad draining cappotential because of it tiny bad spaces .

Tropical placing in a coastal surroundings affords the important environments for soils like peat to shape . It has plentiful of plant stays . Moreover peat is the primary degree of coal formation, containing wet and unconsolidated plant substances.

Minerals part of what help withinside the improvement of the soil .And additionally it is carried right all the way down to the earth with the aid of using water thru a procedure referred to as Leaching.

Richness of nutrient are not unusualplace in tropical surroundings which are moist and help plentiful life.

Sandy soil are fashioned from dad and mom substances containing minerals together with feldspar and quartz.

Horizon O and A are referred to as topsoil and are specifically compose of animal and flora stays and big quantity of minerals.

The subsoil or B Horizons consists of mineral together with irons , clay minerals because of percolation from the pinnacle soils and it has a tendency to build up here(subsoil).

Which of the following are true statements about equilibrium systems? For the following reaction at equilibrium: CaCO3(s) ⇌ CaO(

Grace [21]

Answer:

The first, third and fourth statements are correct.

Explanation:

1) For the following reaction at equilibrium: CaCO3(s) ⇌ CaO(s) + CO2(g) adding more CaCO3 will shift the equilibrium to the right.

⇒ Le Chatellier says As the CaCO3 concentration is increased, the system will attempt to undo that concentration change by shifting the balance to the right. <u>This statement is true.</u>

<u />

2) For the following reaction at equilibrium: CaCO3(s)⇌ CaO(s) + CO2(g) increasing the total pressure by adding Ar(g) will shift the equilibrium to the right.

⇒ Le chatellier says that if we increase the pressure, the equilibrium will shift to the side with the least number of particles.

Since the molar densities of CaO and CaCO3 are constant, they don't appear in the equilibrium expression. This is why only changes to the pressure (concentration) of CO2 affect the position of the equilibrium.

If the pressure in the container is increased by adding an inert or non-reacting gas, nothing happens to the amounts of CO2, CaO or CaCO3. The added gas won't affect the partial pressure of CO2. <u>This statement is false. </u>

3)For the following reaction at equilibrium: 2 H2(g) + O2(g) ⇌ 2 H2O(g) the equilibrium will shift to the left if the volume is doubled.

⇒ Le Chatellier says if we increase the pressure, the equilibrium will shift to the side with the most particles.

In this case we have 2 moles of H2 and 1 mole of O2 on the left side and 2 mole of H2O on the right side. This means on the left side are more particles. So the equilibrium will shift to the left, so <u>this statement is true.</u>

4) For the following reaction at equilibrium: H2(g) + F2(g) ⇌ 2HF(g) removing H2 will increase the amount of F2 present once equilibrium is reestablished. Increasing the temperature of an endothermic reaction shifts the equilibrium position to the right.

⇒ Le chatellier says if H2 will be removed (this means the left side will get less particles) so the equilibrium will shift to the left, to increase the amount of F2.

⇒Le chatelier says if we increase the temperature of an exotherm reaction , there will be less energy released. The equilibrium will shift to the side of the reactants (the left side).

If we increase the temperature of an endotherm reaction, the equilibrium will shift to the side of the products (the right side). <u>This statement is true.</u>
