So the molarity equation is moles of solute/liters of solution. so i’m pretty sure the answer should be 0.63/0.70= .9
Answer:
2= its color
Explanation:
Transition elements are present in the middle of periodic table. These are d-block elements.
These are 38 elements.
All transition elements have partially filled d orbitals.
They showed color in compound because of d-d transition.
During the d-d transition electron absorbed the energy and emit the reminder energy. The emission is usually in the form of color light.
The color of ion is complementary to the absorbed color.
The transition elements are used as a catalyst in industries such as polymer, petroleum industries.
They are ductile, conduct heat and electricity.
The monomers that react together to form polyurethane polymer are diisocyanate and diol.

What are polymers?</h3>
- Polymers are a class of natural or synthetic substances
- It is made up of small units called monomers arranged in a repeated pattern to form large molecules called macromolecules
- Cellulose and resins are examples of natural polymers
- Polyethylene and polychloroprene are examples of synthetic polymers.
Polyurethane polymer is made up of monomers diisocyanate and diol. It is mostly used in home furnishing in flexible form. The structures of monomers are as follows:
