Cross-linked polymers are strong and heat - resistant hence they can be used for this purpose.
A polymer is obtained by the combination of small molecules called monomers. A polymer consists of a regular repeating unit of small molecules called monomers.
A cross-linked polymer is a polymer in which covalent bonds are used to join polymer chains together. Cross-linked polymers are strong and heat - resistant hence they can be used for this purpose.

Well if the change is reversible then it is a physical change, but if not then it is a chemical change.
<span>The transferred electron from lithium to fluorine provides each atom with a full outer energy level.</span>
Answer:
Do you need the definition or the equation to find it?
Explanation:
Equation:
Mass=volume x density
2Mg+ O₂= 2MgO
The charge of Mg is+2 and the charge of Oxygen is -2. 2 oxygen atoms will have a charge of -4 so the Mg atoms have to equal +4. A coefficient of 2 for the Mg atoms will balance it out
