Helga [31]

Polyester is a condensation polymer of dicarboxylic acid and diol. Example : Polethylene terphthalate is polymer of ethylene glycol and tere phthallic acid. When a strong acid like HCl or a strong base like NaOH comes in contact with polyester (like spilled on slacks) it causes hydrolysis of polyester and it get converted back to dicarboxylic and diol(the monomers). the general reaction will be RCOOR' ---> RCOOH + R'OH Thus slacks will get teared.

Ammonia is produced by the chemical reaction of hydrogen and nitrogen
MaRussiya [10]

Answer:

3.6 mol H₂

Explanation:

  • N₂ + 2H₂ → 2NH₃

In order to convert from N₂ moles to H₂ moles we need to use a conversion factor. This conversion factor has to have<u> N₂ moles in the denominator and H₂ moles in the numerator</u>, using the <em>stoichiometric coefficients</em> of the reaction, as follows:

  • 1.8 mol N₂ * \frac{2molH_2}{1molN_2} = 3.6 mol H₂
