<span>What are some examples of monomers and oligomers?
</span>Organic molecules, such as proteins, carbohydrates, lipids and nucleic acids, are made of simple subunits called monomers. <span>Plasticizers are </span>oligomeric esters widely used to soften thermoplastics such as PVC and <span>urethane acrylate </span>.

</span><span>If a chemical compound accelerates and regulates metabolic reactions, which type of role does it play - structural or physiological?
</span>I believe the function that it plays would be physiological since it focuses more on the regulation of the reactions inside the body.
Answer: By performing the flame test
Explanation:
The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.
The reaction for burning of charcoal or complete combustion is as follows:
From the above balanced reaction, 1 mole of carbon releases 1 mole of 
gas.
Converting mass of charcoal into moles as follows:
Molar mass of pure carbon is 12 g/mol thus,
The same moles of is released. Converting these moles into mass as follows:
m=n×M
Molar mass of is 44 g/mol thus,
Converting mass into kg,
Thus, total mass of gas released is 5.5 kg.
