The correct answer would be option 3. I order for a single displacement to occur there must be a single element and one compound. From then, the single element will then swap places with one of the elements in the compound (or in this case single circle and combined circles). Hope this helped!

adell [148]

Fluids used for an intravenous fluid transfusion must be isosmotic with bodily fluids.

Intravenous fluids, sometimes abbreviated as "IV fluids," are liquids that are administered to replace water, sugar, and salt that you may need if you're ill or having surgery and are unable to eat or drink regularly. Through a drip, Intravenous fluids are administered directly into a vein.

In order to treat or prevent dehydration, Intravenous fluids are carefully prepared liquids that are injected into a vein. They are applied to patients of all ages who are ill, hurt, becoming dehydrated from physical activity or the heat, or who are having surgery. Rehydrating intravenously is a straightforward, risk-free treatment that is frequently used.

How many repeat units are required to make a nylon polymer with a formula weight of 15,000 amu?
Y_Kistochka [10]

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.
