These goats are eating grass on a sunny day. What is happening to the carbon in the air around the living things on the mountain
polet [3.4K]

Answer:

both

Explanation:

Carbon in the air around the living thing is moving in and out of its lungs. The movement is occurring at the same time. This is one of the most important gaseous exchange important to life.

  • The goats takes in oxygen gas from the surrounding and releases carbon dioxide in the process.
  • But, air is actually drawn in by the goat which is a mixture of several gases.
  • Air contains carbon dioxide which is a rich source of carbon
  • With the carbon dioxide from respiratory processes, the goat ejects and breathes out this waste carbon matter.
  • Therefore, the gaseous exchange in a goat involves the movement of carbon in and out of the air.

"how many molecules of carbon dioxide exit your lungs when you exhale 5.00 × 10−2 mol of carbon dioxide, co2?"
IrinaVladis [17]
We are going to use Avogadro's constant to calculate how many molecules of

carbons dioxide exist in lungs:

when 1 mole of CO2 has 6.02 x 10^23 molecules, so how many molecules in

CO2 when the number of moles is 5 x 10^-2

number of molecules = moles of CO2 * Avogadro's number

                                     = 5 x 10^-2  * 6.02 x 10^23

                                     = 3 x 10^22 molecules 

∴ There are 3 x 10^22 molecules in CO2 exist in lungs
