alexandr1967 [171]

Answer:

Phosphorus Mineralization

Explanation:

Organisms are bound to die when they do, they undergo decomposition which breaks down complex organic matter into simpler organic matter. The simpler organic matter also undergoes other processes that result in the production of simple inorganic matter; One of such processes is Phosphorus mineralization, it is the process by which phosphorus contained in organic matter is converted to simple inorganic phosphates.

The sun supplies about 1.0 kilowatt of energy for each square meter of surface area (1.0 kW/m^2 where a watt = 1 kJ/s) Plants pr

kaheart [24]

Answer:

0.092 %

Explanation:

The equation of the reaction can be computed as :

$12CO_2_{(g)} + 11H_2O_{(l)} \to C_{12}H_{22}O_{11} + 12O_{2_(g)}$

$\Delta H = 5645 \ kJ$

recall that; the number of moles = $\dfrac{mass}{molar \ mass}$

By applying the method of enthalpy of combustion for sucrose at the same time changing the time from hours to seconds, we can determine the total energy output.

i.e

$=\dfrac{0.20g \ of \ sucrose }{m^2 \ 3600 \ s}\times \dfrac{1 \ mol}{342.34 \ g}\times 5.645 kJ/mol$

$= 9.16 \times 10^{-4} \ kJ/m^2 s$

Given that the sun supplies about 1.0 kilowatt, to KJ/m² s, we have:

$1.0 \dfrac{kW}{m^2 }= 1.0 \dfrac{kJ}{m^2 s}$

Finally, the percentage of sunlight used to produce sucrose :

= $\dfrac{9.16 \times 10^{-4} \ kJ/m^2 \ s}{1.0 \ kJ/m^2 . s} \times 100\%$

= 0.092 %
