In case of a shortage in petroleum and natural gas, a company should find a way to make nylon without using natural resources.

Nylon is a very important material used in numerous applications. As a result of this, the demand for nylon as a raw material has genuinely been on the high side ever since.

However, nylon production depends on petroleum and natural gas. It is possible that there could be a shortage of these resources since they are obtained from the environment. In such cases, a company should  find a way to make nylon without using natural resources.

Explanation:

1)  I personally would want to learn more about how the waves in the ocean move. About what causes high tide. What causes low tide. Why some waves are big and some small.  

I know it has something to do with the gravitational pull of the moon. But that is as far as my knowledge extends on the subject. I have always been fascinated with the secrets of the ocean and the secrets of space. To me learning, this is a little of both.

2)  The nature of the interaction between neutrons and protons in the atomic nucleus, which binds the nucleons together, is the biggest wonder in the inside of the atom that I would like to really know. Protons have a positive charge, but neutrons do not. What form of interaction between a charged particle and an uncharged particle is possible? That is what I expect to learn more about as a result of my explorations into the inner workings of the atom.

The inside of the atom is made up of the nucleus and electrons that travel about in orbits. The nucleus is made up of protons and neutrons. Electrons have a negative charge, protons have a positive charge, and neutrons have none. The nucleus is held together by electrostatic interaction between electrons and protons. The majority of the mass of an atom is made up of protons and neutrons.

I'm interested in finding out more about ocean waves travel. regarding the reason for high tide. what brings on a low tide. Although some waves become also large while others are smaller.

Ocean waves seem to be alterations to the ocean's surface. They could be produced by water being moved by the wind, gravity, as well as other forces.

A disturbance that moves from one place to another across a medium has been referred to as a wave. As an illustration of a wave, think of a sinuous wave.

Answer:

Even though the two substances possess many similarities, they have some unique properties. In turn, since they have the same properties, if they were the same substance, it would make matters worse, if the same chemical was in two different places, there would not be a difference between them since they are the same, just as it is with are two different chemicals would have differing properties since they are two properties would vary from one another since they are 2 totally different things!

The neutral atom is isoelectronic with N⁻³ is Neon (Ne).

Isoelectronic are those which have same number of electrons or we can say that same electronic structure.

For finding out that the species are isoelectronic , we just have to count there no. of electrons of atoms and if they have same no. of electron then they said to be isoelectronic species.

no. of electrons in Nitrogen N = 7 ( atomic no.)

no. of electrons in Nitride ion N⁻³ = 7 + 3 = 10

no. of electrons in Neon Ne = 10 ( atomic no. and neutral atom)

so, no. of electrons in Nitride ion N⁻³  = no. of electron in Neon Ne

this means , N⁻³ , Nitride ion is isoelectronic with Neon Ne.

Thus, The neutral atom is isoelectronic with N⁻³ is Neon (Ne).

Answer:

how much matter is in an object

Explanation:

Answer:

17550g

Explanation:

You want to use the equation D=M/V. You are given density in g/mL, so you just need to multiply that by 9L, but first you want the mL and L to match, so you change the 9L to 9000mL (knowing there is 1000mL in 1L). Then solve algebraically by multiplying the 9000mL and the 1.95g/ml, making the mL cancel, leaving you with your answer in grams.

The mass of oxygen required for complete utilization of 4 mol of Mg has been 64 g. Thus, option B is correct.

The balanced equation for the reaction has been:

[tex]\rm 2\;Mg\;+\;O_2\;\rightarrow\;2\;MgO[/tex]

From the balanced chemical equation, for complete utilization of 2 moles of Mg, 1 moles of oxygen has been used.

The given moles of Mg has been 4 mol. The moles of oxygen required can be given as:

[tex]\rm 2\;mol\;Mg=1\;mol\;O_2\\4\;mol\;Mg=2\;mol\;O_2[/tex]

Thus, the moles of oxygen required has been 2 mol for complete utilization of 4 mol Mg.

The mass from moles can be calculated as:

[tex]\rm Mass=Moles\;\times\;molecular\;mass[/tex]

The molecular mass of oxygen has been 32 g/mol.

The mass of oxygen has been:

[tex]\rm Mass=2\;\times\;32\;g\\Mass=64\;g[/tex]

The mass of oxygen required for complete utilization of 4 mol of Mg has been 64 g. Thus, option B is correct.

One possible reason why many studies on antioxidant supplements do not show a health benefit is because antioxidants tend to work best in combination with other nutrients, plant chemicals, and even other antioxidants.

Explanation:

Answer:

There are four natural states of matter: Solids, liquids, gases and plasma. ... Solids have a definite shape, as well as mass and volume, and do not conform to the shape of the container in which they are placed. Solids also have a high density, meaning that the particles are tightly packed together.

There are 0.436 moles of nitrogen dioxide, NO2, present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L.

The number of moles of nitrogen dioxide (NO2) in this question can be calculated by using the ideal gas law equation as follows:

PV = nRT

Where;

According to the reaction conditions given in this question;

2.46 × 4.8 = n × 0.0821 × 330

11.81 = 27.093n

n = 11.81 ÷ 27.093

n = 0.436mol

Therefore, there are 0.436 moles of nitrogen dioxide, NO2, present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L.

Rebekah reports the volume of sugar solution using metric system as 39.1 mL. Thus, option D is correct.

The metric system has been the measurement system introduced in 1790s. The system has mediated the units for the measurement of volume, mass, length.

The volume has been the space that has been occupied by matter. The volume can be denoted with SI unit L. However, the another accepted unit for volume has been mL.

Thus, the volume of sugar solution has been reported in mL.

The given sugar solution has volume of 1.32 fl. Oz

The volume in mL can be given as:

[tex]\rm 1\;fl\;Oz=29.6\;mL\\1.32\;fl\;Oz=1.32\;\times\;29.6\;mL\\1.32\;fl\;Oz=39.1\;mL[/tex]

The volume of the sugar solution reported by Rebekah on the metric scale has been 39.1 mL. Thus, option D is correct.
