Answer:
- Lipids: used for long-term energy storage
- Nucleic acids: used for storing and transmitting genetic information
- Protein: used for tissue repair and growth
- Carbohydrates: used for energy
Explanation:
These terms simply have to be memorized, but understanding their structure can help you gain a better grasp of their functions. Lipids have fatty acid chains with lots of bonds, so they are high energy. Nucleic acids have pieces that can be rearranged into many combinations that can be read by certain structures. Proteins are composed of different building blocks with different properties. The sum of these properties is the function of the protein. Lastly, carbohydrates have compact monomers that are extremely easy to break apart into energy.
Answer:
V = 0.23 Lt
Explanation:
Data: O₂ 4.50 g = 0.14 mol (considering a molecular mass of 32 g for O₂)
V₁ = 15.0 Lt , T₁ = 203 K , P₁ = 5.0 atm
V₂ = ? , T₂ = 303 K , P₂ = 15.0 atm
If we consider that this gas beahves as an ideal gas, then:
PV = nRT
V = nRT/P
V₂ = nRT₂/P₂ , where R gas constant = 0.082 Lt*atm/K*mol
V₂ = (0.14x0.082x303)/15.0 ⇒ V₂ = 0.23 Lt
Which is consistent, considering that the gas is subjected to a high pressure (from 5 atm to 15 atm), its volume should decrease (from 15 Lt to 0.23 Lt)
