Question

Forests and soils contain roughly 2160 Gton of carbon in the form of wood, leaves, and humus. (The actual value is not known this accurately, but this choice makes the numbers work out well.) Suppose that all of the world’s forests were to burn down instantaneously and that all of the soil carbon was oxidized as well.By how much would atmospheric CO₂ increase? By how much would O₂ decrease? Express your answers in percentages. Assume that the burning equation is same as that for respiration and decay:

CH2O + O2 --> CO2 + H2O.

Express your answer in a percentage.

Answer 1

Answers Page nooo 70 Given, Forests and soils contain roughly 2160 Giton of Carbon in the form of wood, leaves. and humus. Rorests contain 600 gigatons of carbon in the form of wood and leaves. If all these woods and leaves burn automatically the Carbon levels will increase and oxygen levels decreases. If the outrospherie Carbon dioxide implies 7944.82 gica tory of Carbon dioxide. That means 2017,93 ppm. 1017,93 ppm constitutes 0.1007 %. by volume of the atmosphere The atmosphere consists of 0.04% of Carbon dioxide, if the woods burn this rate is increased by 0.100 and becomes total of 0.1407 % in the atmosphere. This situation result in the decrease in the levels onggen. Atmosphere Contains of nearly 21% of Oxygen. Generally when the woods and leaves burn they releases some amount of carbon dioxide into the air at the same time how much they release

Page No- the Carbon dioxide that much amount of ouygen they take so nearly 0.1007 % of the aggen forest takes during the burning proces. The amount of oxygen present in the atmosphere is nearly 21% from that if we Subtract the reduced onygen levels, then the amount of Onygen present in the nature is 20.89 %
