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.
The volume of one mole of any gas at STP is 22.4 L. So, at STP, the volume of 2.00 moles of hydrogen gas would be (22.4 L/mol)(2 mol H2) = 44.8 L.

A pure substance refers to an element or a compound that has no component of another compound or element. Pure substances are made of only one type of atom or molecule. Hydrogen gas and pure iron are examples of pure substances. Hydrogen consists of hydrogen atoms only while iron consists of only iron atoms. Mixing two pure substances results in a mixture. To separate the two, scientists use a method known as filtration. Mixtures can either be homogeneous or heterogeneous. The measure used to determine how pure a substance may be called purity. Besides hydrogen and iron, other pure substances include gold, diamonds, sugar, and baking soda.
