CICLOS BIOGEOQUIMICOS: lugares en que encontramos el elemento del ciclo separando en bioticos y abioticos
scoundrel [369]

Answer:

Los ciclos biogeoquímicos son definidos como la circulación de los elementos químicos entre organismos biológicos (es decir, el factor biótico del ciclo), y componentes geológicos inorgánicos del sistema (factores abióticos). En el ciclo del agua, por ejemplo, este elemento se encuentra esparcido en los ríos y arroyos, como así también en la atmósfera, desde donde fluye como lluvia hasta el suelo y puede ser ingerida por organismos vivos terrestres y es utilizada para llevar a cabo diversas funciones celulares.

Explanation:  

Los ciclos biogeoquímicos establecen un vinculo entre los factores bióticos y abióticos del ecosistema, de modo que la energía puede fluir libremente a través de ambas partes del sistema. Los seres vivos necesitan diferentes elementos químicos para sobrevivir, los cuales forma parte de los ciclos biogeoquímicos. En los ciclos biogeoquímicos los elementos se conocen como 'nutrientes' (micro y macronutrientes). Estos elementos se encuentran esparcidos tanto en la corteza de la tierra como en la biósfera. Los nutrientes son indispensables porque de ellos depende de que la energía fluya entre el componente inorgánico y orgánico del ciclo. Por otra parte, los nutrientes también circulan dentro del ciclo entre componentes bióticos de la cadena trófica, con lo cual no sólo los nutrientes sino también la energía fluye entre organismos, desde aquellos más basales en el sistema tales como plantas (ecosistemas terrestres) o algas (marinos), hasta los niveles superiores representados por especies animales hervívoras y carnívoras de tales ecosistemas.

The heat equation, as given in the introduction, can also be rearranged to calculate the mass or temperature change for a substa
notka56 [123]

Answer:

The correct answer is 281.39 grams.

Explanation:

To arrive at this answer you must first keep in mind the basic equation:

<em>Q = m*Cp* ΔT</em>

Now, in order to calculate the necessary aluminum mass that absorbs 2138 J when passing from 14.83 to 23.31 ° C you must "clear" <em>m</em> of the previous equation.

This means, leave only the mass on one side of the equation, and "pass" <em>Cp</em> and <em>ΔT</em> to the other side dividing <em>Q</em>.  This would look like this:

m= Q/ (Cp*ΔT)

Then, <u>you need the value of specific heat of aluminum</u> in the correct units, that is J / g ° C, the approximate value is 0.896.

ΔT is calculated by doing the mathematical operation:

23.31 °C - 14.83 °C = 8.48 °C

<em> Finally, the values of: Q (data provided in joules), Cp (J / g ° C) and ΔT (calculated in ° C) are replaced in the last equation and the mass (in grams) is calculated resulting in 281.39 grams.</em>
