Balance the combustion reaction between octane and oxygen. 2C8H18 + O2 → CO2 + H2O

Chemistry
2 answers:
Ber [7]3 years ago
6 0

Explanation:

A balanced reaction is a reaction where there are equal number of atoms on both reactant and product side.

For example, 2C_{8}H_{18} + O_{2} \rightarrow CO_{2} + H_{2}O

Number of atoms on reactant side are as follows.

  • C = 16
  • H = 36
  • O = 2

Number of atoms on product side are as follows.

  • C = 1
  • H = 2
  • O = 3

Therefore, in order to balance the equation we multiply O_{2} by 25 on reactant side and multiply CO_{2} by 16 and H_{2}O by 18.

Thus, the balanced chemical equation will be as follows.

       2C_{8}H_{18} + 25O_{2} \rightarrow 16CO_{2} + 18H_{2}O

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

Name the type of bond between atoms in ammonia molecule. Give a reason for your answer
Likurg_2 [28]

Answer:

Covalent bonds are formed when electrons are shared between elements that are nonmetals. The ammonium ion, NH+4 , would have covalent bonds because both nitrogen and hydrogen are nonmetals. ... The rest of the bonds all contain electrons from both hydrogen and nitrogen, so they would be considered ordinary covalent bonds.
