<u>Answer:</u>

<em>B. Cotton</em>

<em></em>

<u>Explanation:</u>

A polymer is a macro molecule or gaint molecule which is formed as a chain from  many small molecules(which is called as a monomer).

Polymer is a repeating unit of many monomers.

For example  

Ethylene or ethane formula is C2H4.

Many ethane molecules under particular temperature and pressure conditions undergo the polymerization process to form polyethene. During this process the double bond breaks and becomes single bond and produces a long chain which we call it as a polymer.

The repeating unit of Cotton polymer is called as Cellubiose which is made up of 2 glucose units.

The number of units which forms the polymer (degree of polymerization) is about 5000 cellubiose units.

The combustion of Ibuprofen C13H18O2 produces water and carbon
prohojiy [21]

Answer:

277.7 g of CO2

Explanation:

Equation of reaction

C13H18O2 + 11O2 ---> 13CO2 + 9H2O

From the equation of reaction

1 mole of ibuprofen produces 13 moles of CO2

Molar mass of ibuprofen is 206g

Molar mass of CO2 is 44g

13 moles of CO2 weighs 572g

Therefore, 100g of ibuprofen will produce (100×572)/206 of CO2

= 277.7g
