Draw the structures of the two monomers that react together to form this polyurethane polymer
matrenka [14]

The monomers that react together to form polyurethane polymer are diisocyanate and diol.

<h3>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:

denpristay [2]

<span>For number two, the equation is balanced. Na in the reactant side has one atom and also in the product side. O has only one atom in the product and in the reactant. There are 2H’s in the reactant and in the product side (present in H2O, the 2 in H stands for 2 atoms of H). One atom of Cl is present in the reactant and product side.</span>

 

For number three, the reactants are NaOH-sodium hydroxide and HCl-hydrogen chloride(hydrochloric acid). The products are NaCl-sodium chloride and H2O-water.

An atom of sodium -23 has a net charge of +1 identify the number of protons, neutrons, and electrons in the atom. Then explain h
nikitadnepr [17]

Number of protons is 11

Number of neutrons is 12

Number of electrons is 10

For a neutral Na, Sodium atom:

The mass number P+N = 23

Atomic number (E or P) = 11

A charged Na atom that has lost an electron is positively charged and so:  Number of Protons = 11 (Still the same)

Number of neutrons = 12

Number of electrons = 11-1=10 (the atom has lost an electron)

If an atom loses electron, it becomes positively charged ie. P>E
