Answer : The heat energy required to melt 2 kg of ice was, 667.7 kJ
Explanation :
First we have to calculate the moles of ice.
Now we have to calculate the heat energy.
As, heat energy required to melt 1 mole of ice = 6.01 kJ
So, heat energy required to melt 111.1 mole of ice = 111.1 × 6.01 kJ
= 667.7 kJ
Therefore, the heat energy required to melt 2 kg of ice was, 667.7 kJ
The Structure of polypropylene(C3H6)n is linear.
- The chemical formula for polypropylene is (C3H6)n.
- It is a polymer with complex structure and also known as polypropene.
- Polypropylene is similar to polyethylene which belongs to polyolefin groups.
- Generally the polymers are synthesized from the polymerization process.
- What is polymerization?
The process in which atom or small molecules joined together repeatedly to form a polymer with complex structure is called as polymerization.
The repeated unit of atom or small molecule is called monomer
<h3>Structure of polypropylene</h3>Polypropylene is synthesized from the polymerization of propylene which is the monomer unit.
It has a linear structure made of propylene hydrocarbon units.
