Answer :
The rate of appearance of o2 at that moment is 2.80 mol/min.
Calculation :
Recall
aA+bB→ cC+dD
[tex]\frac{d[A]}{a.dt}[/tex] = [tex]\frac{d[B]}{b.dt}[/tex] = [tex]\frac{d[C]}{c.dt}[/tex] = [tex]\frac{d[D]}{d.dt}[/tex]
Then
[tex]\frac{d[NO_{2} ]}{2.dt}[/tex] = [tex]\frac{d[NO_{2} ]}{4.dt}[/tex]
Replacing :
[tex]\frac{1.4}{2}[/tex] = [tex]\frac{d[NO_{2} ]}{4.dt}[/tex] ....... [tex]\frac{d[NO_{2} ]}{dt}[/tex] = 2.8
Degradation is the first step in the recycling of nutrients that an organism (plant or animal) uses to build its body. This is the process by which dead tissue is broken down and transformed into simpler organic forms.They are the food source for many species that underlie ecosystems.
Decomposition or putrefaction is the process by which dead organic matter breaks down into simple organic or inorganic matter such as carbon dioxide, water, simple sugars and inorganic salts. This process is part of the nutrient cycle and is essential for recycling the finite substances that occupy the physical space of the biosphere. An organism's body begins to decompose shortly after death. Animals such as earthworms also help break down organic matter.
