How many repeat units are required to make a nylon polymer with a formula weight of 15,000 amu?

Chemistry

This problem is giving information about a nylon polymer whose molar mass is 15,000 amu (atomic mass units).

The first subject of matter here, is to recall the monomeric molecular formula of nylon which is C₁₂H₂₂N₂O₂, and the definition of monomer (basic molecule able to react and form a polymer) and polymer (assembling of monomers).

Next, we calculate the molar mass of the monomer of nylon:

12*12.01+22*1.01+2*14.01+2*16.00=226.31amu

Finally, the number of units is calculated by dividing the molar mass of the polymer and the monomers:

n=\frac{15000}{226.31} =66.2

Which is about 66 monomers.

Cytotoxic t cells can attack target cells with which chemical weapons?
Aneli [31]

Answer:

secrete cytotoxic substance which triggers apoptosis of target cell.

Explanation:

Cytotoxic T cells have cell surface receptor which recognizes the antigen present on the receptor of target cell. This interaction initiates the process of killing of target cell.

After interaction cytotoxic t cell release cytotoxic substance called granzyme and perforin. Granzyme triggers apoptosis through the activation of caspases or by making the release of cytochrome c and activation of the apoptosome.

Perforin make pores in the cell and its action is similar to complement membrane attack complex. Therefore cytotoxic substances are released by Tc cells which trigger apoptosis of target cell.
