Answer:

Los combustibles fósiles son una serie de sustancias y gases formados a partir de restos descompuestos de animales y plantas. Estas sustancias se generan en ciertas capas del suelo durante el transcurso de millones de años. Precisamente, debido al tiempo necesario para generarse se considera que es un tipo de energía no renovable.

Explanation:

Los combustibles fósiles se forman mediante un proceso de descomposición parcial de la materia orgánica. Se trata de un proceso de transformación de millones de años debido a la presión y temperatura que varias capas de sedimentos ejercen sobre la materia orgánica.

Se han originado de forma natural por un proceso de fosilización en anoxia (falta de oxígeno) ambiental: la materia orgánica no se ha degradado por microorganismos (que no pueden vivir), sino que permanece en forma de moléculas orgánicas más complejas, sólidas (carbón), líquidas (petróleo) o gas (gas natural). La energía de estas moléculas es la que se libera en utilizarlos como combustible.

Este proceso de millones de años es el que convierte los combustibles fósiles en una fuente de energía no renovable, ya que se consume mucho más rápido que no se genera.

Answer:

Fossil fuels are made from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.

love history [14]

T_1=27°C
T_2=40°C
V_1=1L
V_2=?

Using Charles law

$\boxed{\sf \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}}$

$\\ \sf\longmapsto V_1T_2=V_2T_1$

$\\ \sf\longmapsto 1(40)=27V_2$

$\\ \sf\longmapsto V_2=\dfrac{40}{27}$

$\\ \sf\longmapsto V_2=1.48\ell$

How many of the following molecules have sp2 hybridization on the central atom? hcn so2 ocl2 xecl2.

GrogVix [38]

Only one molecule have sp2 hybridization on central atom and that is SO₂.

XeCl₂ have sp3d hybridization.

OCl₂ have sp3 hybridization.

HCN have sp hybridization.

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

Hybridization intermixing usually results in the formation of hybrid orbitals having entirely different energies, shapes, etc.

Why is mitosis a form of asexual reproduction?

sukhopar [10]

Asexual reproduction involves mitosis. It could be by a number of different ways, but all of them involve making new cells from the ones that are already there.

Note that mitosis is also valuable for repairing damaged tissue, replacing worn out cells, growing, and developing, not just asexual reproduction.

Asexual reproduction does not occur by meiosis.
