Answer:

  • Sedimentation: Sedimentation is the process of allowing particles in suspension in water to settle out of the suspension under the effect of gravity.
  • Decantation: Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture

hope u liked the answer :)

(a) sedimentation ---> <em><u>the process of leaving sediment.</u></em>

(b)decantation ---> <em><u>a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension</u></em>

Lithosphere: Odd one out . Analyze each part of the rectangle. One of the parts will be different from the others. Shade the par
patriot [66]

The characteristics of the lithosphere found that the frame that is out of sequence is:  

       last frame: Iron

The lithosphere is the upper part of the Earth, it is composed of two parts: the crust and the upper part of the mantle, up to the ionosphere, an area of ​​material in a plastic state.

The lithosphere is the most important part for since all the life processes on the planet occur in it, the depth of the lithosphere is greater in the continental part about 250 km than in the oceanic part 150 km, this is It is because it is floating above the stratosphere.

Let's analyze each part of the picture

1. Rigid rocks in the upper part of the mantle.

The lithosphere is the coldest part of the plant, which is why the rocks have solidified, forming a rigid layer of rocks that floats on the mantle.

2. Crust.

It is another name given the uppermost part of the lithosphere, it is formed by a solid area,

3. Tectonic plates.

The lower part of the lithosphere is on an area in a very hot platic state, therefore there is a thermal gradient between the convection current of the asthenosphere and the thermal conduction of the lithosphere, these thermal gradients create breaks or divisions in the upper layer that we call plate tectonics

4.) solid crust of the Earth

The lithosphere is by definition the solid part of the Earth, which is why it is also called solid crust, but not rigid.

5) Continents.  

They are the highest parts of the lithosphere, they are above the average height of the oceanic that forms the liquid part that fills the lower spaces of the lithosphere, in general it is formed by rocks of granite composition

6) Earthquakes

The plates of the lithosphere can move between it, in some cases these plates are locked (stopped) accumulating energy at some point the rocks that form part and the plates move abruptly this movement is called an earthquake

7) Volcanoes

The lower part of the lithosphere is hotter, in some parts where the upper rock is more fragile, this heat can fragment them, which is why the molten rock called magna has an exit path towards the earth's surface, in general the fragmentation processes and rupture is accompanied by high pressures that make the surface rise in height, these structures are called volcanoes, the vast majority are near the contact zone of the tectonic plates,

8) Iron  

This is a chemical element that is one of the constituents of the lithospheres, but it is not an essential part of its structure. Iron, for being a heavy element, is believed to be fundamentally in the Earth's nucleus, in the lithosphere it only forms 4.7% of its structure. This is why this box is out of sequence of the second rectangle

Consequently with the characteristics of the lithosphere found that the frame that is out of sequence is:

              last frame: Iron

Blast furnaces extract pure iron from the iron(III) oxide in iron ore in a two step sequence.In the first step, carbon and oxyge
Alona [7]

Answer:

The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide:

2Fe_2O_3 (s) +6C (s) + 3O_2 (g)\rightarrow 4Fe (s) + 6CO_2 (g)

Explanation:

Step 1: Carbon and oxygen react to form carbon monoxide:

2C (s) + O_2 (g)\rightarrow 2CO (g)..[1]

Step 2: Iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:

Fe_2O_3 (s) + 3CO (g)\rightarrow 2Fe (s) + 3CO_2 (g)..[2]

The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide can be obtained by :

3 × [1] + 2 × [2]

2Fe_2O_3 (s) + 6CO (g)+6C (s) + 3O_2 (g)\rightarrow 4Fe (s) + 6CO_2 (g)+6CO(g)

CO gas will gas cancel out form both sides ans we will get the net chemical equation:

2Fe_2O_3 (s) +6C (s) + 3O_2 (g)\rightarrow 4Fe (s) + 6CO_2 (g)

According to reaction, 2 moles of ferric oxide reacts with 6 moles of carbon and 3 moles of oxygen gas to give 4 moles of iron and 6 moles pf carbon dioxide gas.

Urea is an organic compound widely used as a fertilizer. Its solubility in water allows it to be made into aqueous fertilizer so
skad [1K]

Answer:

3 hydrogen bonds.

Explanation:

This is because the urea molecule has an oxygen atom bound with double bonds to the central carbon atom, and this oxygen can form a hydrogen bond with water, as well as both terminal amine groups that can also form a hydrogen bond each because of the lone pair of electrons on the nitrogen group.
