Chapter 6, Problem 156P(choose chapter or problem)
We hear a lot about how the burning of hydrocarbons produces the greenhouse gas \(\mathrm{CO}_{2}\), but what about the effect of increasing energy consumption on the amount of oxygen in the atmosphere required to sustain life. The figure shows past and projected energy world consumption. (a) How many moles of oxygen would be required to generate the additional energy expenditure for the next decade? (b) What would be the resulting decrease in atmospheric oxygen?

QUESTION:
We hear a lot about how the burning of hydrocarbons produces the greenhouse gas \(\mathrm{CO}_{2}\), but what about the effect of increasing energy consumption on the amount of oxygen in the atmosphere required to sustain life. The figure shows past and projected energy world consumption. (a) How many moles of oxygen would be required to generate the additional energy expenditure for the next decade? (b) What would be the resulting decrease in atmospheric oxygen?
ANSWER:
Step 1 of 3
Here, we calculate the moles of oxygen would be required to generate the additional energy expenditure for the next decade and What would be the resulting decrease in atmospheric.
Heat combustion of methane reaction is as follows.
Now, calculate the heat energy of the reaction.
=
-
= (-393.5kJ + 2(-285.8kJ))-(-74.85kJ)
= -890.3kJ
