Answer:
The liquid collected during distillation when the evaporated substance condenses. A separation technique that uses evaporation to separate substances. The mixture is heated so that one substance evaporates. The vapour is collected and condenses into a liquid.
The mass of water is calculated as follows
find the moles of each reagent
that is moles = mass/molar mass
for H2s = 84.7/ 34= 2.485 moles
O2 = 78.4 / 32 = 2.45 moles
since 2 moles of H2S react with 3 moles of O2 therefore 2.45 moles of oxygen will be used up therefore O2 is the limiting reagent and H2S is in excess
2H2S + 3O2 ----->2So2 + 2H2O
by use of mole ratio between O2 and H20 which is 3:2 the moles of H2O is therefore = 2.45 x2/3= 1.63 moles of H2O
mass of H2O = moles x molar mass
= 1.63 g x 18g/mol = 29.4 g
In the given question according to the information the process of polymerization is an addition polymerization.
<h3>What is polymerization?</h3>
Polymerization is a process in which addition of many small molecules takes place for the formation of a large three dimensional substance known as polymer.
In the polymerization of polyethene the small repeating molecule is ethene and in this process product formed due to the addition process to the double bond of the ethene.
- In condensation polymerisation removal of water molecule or any other molecule takes place.
- In dehydrogenation polymerisation removal of hydrogen molecule takes place.
- In dehydrohalogenation polymerisation removal of hydrogen halide molecule takes place.
Hence given process is an addition polymerisation.
