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.

An alkyne with the molecular formula C5H8 was reduced with H2 and Lindlar's catalyst. Hydroboration-oxidation of the resulting a
irinina [24]

Since the addition of the H2O in the last step of hydroboration is anti-Markovnikov, the starting material is 1-pentyne.

The addition of H2 to C5H8 yields an alkene when a Lindlar catalyst is used. Recall that the Lindlar catalysts poisons the process so that the addition do not go on to produce an alkane.

When hydroboration is carried out on the alkene, we are told that a primary alcohol was obtained. We must note that in the last step of hydroboration, water is added in an anti- Markovnikov manner to yield the primary alcohol. Hence, the starting material must be 1-pentyne as shown in the image attached.

A solution containing CaCl2 is mixed with a solution of Li2C2O4 to form a solution that is 3.5 × 10-4 M in calcium ion and 2.33
Burka [1]

Answer:

B. A precipitate will form since Q > Ksp for calcium oxalate

Explanation:

Ksp of CaC₂O₄ is:

CaC₂O₄(s) ⇄ Ca²⁺ + C₂O₄²⁻

Where Ksp is defined as the product of concentrations of Ca²⁺ and C₂O₄²⁻ in equilibrium:

Ksp = [Ca²⁺][C₂O₄²⁻] = 2.27x10⁻⁹

In the solution, the concentration of calcium ion is 3.5x10⁻⁴M and concentration of oxalate ion is 2.33x10⁻⁴M.

Replacing in Ksp formula:

[3.5x10⁻⁴M][2.33x10⁻⁴M] = 8.155x10⁻⁸. This value is reaction quotient, Q.

If Q is higher than Ksp, the ions will produce the precipitate CaC₂O₄ until [Ca²⁺][C₂O₄²⁻] = Ksp.

Thus, right answer is:

<em>B. A precipitate will form since Q > Ksp for calcium oxalate</em>
