Sulfur is the element used to cross-link the hydrocarbon chains when natural rubber undergoes vulcanization.
The invention relates to cross-linking hydrocarbon polymers with aromatic polyazides in the presence of sulfur. It has been discovered that hydrocarbon polymers can be cross-linked when heated with aromatic polyazides.
Answer:
In the reaction between p-aminophenol and acetic anhydride to form acetaminophen, 4.5 ml of water were added. This was done to recover the product out the container. Water was used as a means of carrying out the product out the container. However, it should be noted that we would want a small amount to be added in order to avoid the product dissolving onto it.
Explanation:
<u>Given:</u>
Moles of CS2 (it cannot be CO2 as mentioned in the question, since O2 reacts with CS2 and not CO2) = 34.5 mol
<u>To determine:</u>
Moles of O2 undergoing the reaction
<u>Explanation:</u>
The reaction is-
CS2 + 3O2 → CO2 + 2SO2
Based on the stoichiometry: 3 moles of O2 reacts with 1 mole of CS2
therefore the moles of O2 that would combine with 34.5 moles of CS2 are
= 3 moles O2 * 34.5 moles CS2/1 mole CS2 = 103.5 moles
Ans: Around 104 moles of O2 would react with 34.5 moles of CS2
