As the molecular weight increases, polymers tend to crystallize due to how harder it is for chains that are side by side to align due to the increasing length of the chain which makes it difficult to turn out the ordered atomic array.

Polymers can be natural or synthetic substances. Polymers can be crystalline or amorphous, depending on how their molecular chains are structured.

Polymers are found in proteins and nucleic acids. Crystalline polymers, have chains that are positioned together, they don't bend easily under pressure. A typical example of a crystalline polymer is a diamond-hard structure.

In summary, whenever there is an increase in molecular weight, there is always a notable decrease in crystallinity. The crystallinity of a polymer generally affects its properties which include properties such as the density of the polymer and its hardness.

The  map that would I bring with me as I navigate the wilderness is Topographic maps.

Because topographic maps use contour lines to indicate the geometry of landforms, they are excellent for wilderness navigation (mountains, valleys, ridges, saddles).

Reading topographic maps has somewhat lost some of its appeal with the development of reliable, accurate GPS devices and phone navigation apps.

However, no matter how sophisticated and costly your equipment is, it could still run out of batteries, malfunction due to excessive dampness, cease functioning in the cold (cough, iPhones), or fall off a cliff and smash.

Additionally, the satellite signal that your device requires to locate you will always decide to go out at the worst possible time.

Answer:

274.2 K

Explanation:

to get from Fahrenheit to Celsius you use your known value, 34 F, and subtract it by 32 = 2, then you multiply it by 5/9 (or .5556) = 1.1 C

to get from Celsius to Kelvin, you just add 273.15, therefore your Kelvin would be 274.2.

(no hablas ingles..)

para pasar de Fahrenheit a Celsius usas tu valor conocido, 34 F, y lo restas por 32 = 2, luego lo multiplicas por 5/9 (o .5556) = 1.1 C

para pasar de Celsius a Kelvin, solo sumas 273,15, por lo que tu Kelvin sería 274,2.

The value of molarity is 1.589mol/dm3.

While molarity is concerned with the moles of a solute in respect to the volume of a solution, molality discusses the moles of a solute in relation to the mass of a solvent.

The quantity of a material dissolved in a given mass of solvent is known as its molality (m), also known as molal concentration. The moles of a solute per kilogram of a solvent are how it is defined.

The quantity of a material in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity. The molar concentration of a solution is another name for molarity.

Molarity equation : M = moles solute / liters solution

Given data

liters of solution = 230ml

mass = 11.7g

    moles of solutes = mass/molar mass

    molar mass of CH3OH= C(12)+H(1*3) +O(16)+1 =32g

      so,  moles of solutes= 11.7g/32g =0.365mol.

Molarity= 0.365mol/230*10^-3 = 0.365mol/0.230L= 1.589mol/dm3.

Answer

Explanation

The given equation for number 2 is:

Note that: When a reactant loses electrons during a reaction, it is called oxidation. When a reactant accumulates electrons during a reaction, it is called reduction.

The percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of agcl when treated with excess ag⁺ is 17.2 percent.

What is mass percent?

The ratio of the mass of the solute contained in a solution to the mass of the solution as a whole is known as the mass percent.

Explanation:

Given:

Mass of sample = 2. 500 g

Mass of AgCl = 1. 750 g

The percent of chloride ion in a sample is calculated as,

Molar mass of AgCl = 143.32 g/mol

[tex]Molar mass of Chlorine atom = 35.45 g/mol[/tex]

Assume that all of the sample's chlorine has precipitated into silver chloride. As a result, the amount of chlorine in silver chloride will match the amount of chlorine in the sample.

First we have to find mass of chlorine,

[tex]In 143.32 g of silver chloride, mass of chlorine present is 35.45 gSo, in 1.3487 g of silver chloride, mass of chlorine present will be =35.45g/143.32 g * 1.750 g = 0.43 g[/tex]

Therefore, the percent of chloride ion in a sample is

[tex]Mass of pure chloride compound = 2.500 gMass of chlorine = 0.43 g%Chlorine = 0.43/2.5 *100%Chlorine = 17.2 %[/tex]

Hence, the percent of chloride ion in a sample is [tex]17.2%[/tex] percent.

Iron – Ferrum (Fe)

Iron's Latin name, 'ferrum', gives it its symbol Fe; it simply means 'iron' or 'sword', and is possibly of Semitic origin.

Explanation:

We have to balance the following equation:

__ H₂O + __ F₂ -------> __ HF + __ O₂

First we have to determine the number of atoms of each element that we have on both sides of the equation.

__ H₂O + __ F₂ -------> __ HF + __ O₂

O: 1 O: 2

H: 2 H: 1

F: 2 F: 1

We have 2 atoms of O on the right side and 1 atom of O on the left side. To balance the O atoms we can change the coefficient for H₂O and write a 2 in front of it.

2 H₂O + __ F₂ -------> __ HF + __ O₂

O: 2 O: 2

H: 4 H: 1

F: 2 F: 1

Then we have 4 atoms of H on the left and 1 atom of H on the right side of the equation. We can change the coefficient for HF to balance the H atoms.

2 H₂O + __ F₂ -------> 4 HF + __ O₂

O: 2 O: 2

H: 4 H: 4

F: 2 F: 4

And finally we have 2 atoms of F on the left and 4 atoms of F on the right. We can change the coefficient for F₂ and write a 2 there.

2 H₂O + 2 F₂ -------> 4 HF + __ O₂

O: 2 O: 2

H: 4 H: 4

F: 4 F: 4

The equation is balanced.

Liquids have characteristics that fall somewhere in between those of solids and gases, yet they resemble solids more. Intermolecular forces, as opposed to intramolecular forces, such as the covalent bonds that bind atoms in molecules and polyatomic ions, keep molecules in a liquid or solid together. In comparison to covalent bonds, intermolecular forces are often significantly weaker. For instance, in 1 mol of water, the intramolecular forces must be overcome in order to break both O-H bonds, while the intermolecular forces must be overcome in order to turn 1 mol of liquid water into water vapor at 100 °C, which needs just around 41 kJ. (Despite this figure appearing to be modest, the intermolecular forces in liquid water are some of the highest intermolecular forces ever measured.
