Synthetic fibers, like plastic, are derived from organic compounds. These fibers have been chemically changed by humans to last longer for better storage and more effective uses. These fibers are stronger than naturally occurring fibers like cotton and wool. Which of the following is a downside to these synthetic fibers when compared to natural fibers?
A.
The longer lasting material is more difficult to break down.
B.
The longer lasting material is less useful in manufacturing.
C.
The longer lasting material is not able to withstand high temperatures.
D.
The longer lasting material makes the fibers more expensive to buy.

Answers

The downside of this is that the longer lasting material is more difficult to break down.

Both natural fibers and synthetic fibers are polymer materials. Polymer materials are materials that are made by the agglomeration of small molecules called monomers.

The natural fibers are less long lasting than the synthetic fibers. The downside of this is that the longer lasting material is more difficult to break down. As a result of these, synthetic fibers lead to environmental pollution problems.

why does a oxygen atom form a 2- ion

Answers

Answer:

It's because it has 2 electrons on its outer ring

Explanation:

It has a -2 ion due to it having 2 more electrons than protons making it an overall negative. It's well known in chemistry that the first ring can only hold 2 electrons while the second and furthermore can hold up to 8. But what happens when you have 9? a new ring starts and it would only contain 1 electron.. In our case here it has 2 more electrons than protons and those 2 electrons are located on the outer ring

how many molecules are in 122 grams of Cu(NO3)2

Answers

Answer:

3.917 x 10 ^ 23

Explanation:

You just want to use dimensional analysis to solve. So first start with 122g of copper(II) nitrite, and divide by the molecular weight to get it into moles. Then you know that 1 mole = 6.022 x 10 ^23 molecules (Avogadro's Number) so multiply that by your current moles. A hint for these problems always convert what you were given to moles since it is easy to get to a lot of things through them. ** Use the molar mass/molecular weight for going from grams to moles or moles to grams and use Avogadro's number when going from moles to atoms/molecules or reverse.

Answer:

12.5%

Explanation:

percent blurf = quantity of blurftotal quantity×100quantity of blurftotal quantity×100

So for percent by mass, both quantities are expressed as mass, and it’s the mass of NaCl divided by the total mass of the solution, then times 100%

What is a covalent bond?

Covalent bond is defined as a type of bond which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.

Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.

Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

What is a mixture ?

How do homogeneous & heterogeneous mixtures differ ?

Answers

1st question: A mixture is when the components of a mixture can be easily separated and that the components each keep their original properties.

2nd question:A phase is any part of a sample that has a uniform composition and properties.By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers.

Heterogeneous mixtures are not uniform in composition. Examples would be wood or blood. Homogeneous mixtures are uniform through out. Typically you can see through them.

Why does liquid move like it does when heated on the right side?

Answers

Answer:Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids.

Explanation:Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.

A scientist was in the field when he saw a mineral sample. He wanted to determine the relative hardness of the mineral, so he conducted scratch tests. He summarized his results in a table. A 2 column table with 4 rows. The first column is labeled Mineral with known hardness with entries: Chalcopyrite, pyrite, Orthoclase, Quartz. Second column is labeled Was a scratch produced? with entries: Yes, Yes, Yes, No. What conclusion can you make about the hardness of the mineral?.

Answers

The mineral hardness depends on its resistance to being scratched. Mohs scale is used to determine the hardness of an unknown mineral. The unknown mineral is harder than Orthoclase, but not harder than Quartz.

-------------------------

The hardness of a mineral is its resistance to being scratched or marked on the surface by another material.

Several elements are used to test the hardness of a mineral, like another mineral of known hardness.

Many different scales can be used to identify the mineral. However, the most commonly used is the Mohs scale.

Let us say that you have two minerals. You already know which mineral is one of them and its hardness.

If the unknown mineral scratches the known mineral, means that the first one is harder than the second one.

But if the unknown mineral does not get to scratch the known one, it means they are equally hard, or the known mineral is harder than the unknown one.

In the exposed example, the table must be as follows

    Mineral                     Was a scratch produced?              

Chalcopyrite                               YES

pyrite                                           YES

Orthoclase                                  YES                                          

Quartz                                          NO                                            

Quartz is the hardest of these minerals. Its hardness level is 7 according to the Mohs scale.

Because scratches were produced using Chalcopyrite, Pyrite, and Orthoclase, we can assume that the unknown mineral is harder than these three ones.

However, no scratch was produced using quartz, suggesting that the unknown mineral is between orthoclase and quartz in the Mohs scale.

The unknown mineral is harder than Orthoclase, but not harder than Quartz. It is between 6 and 7 hardness levels.
