Which statement best describes the polarity of SCL4F2?
a. The molecule is always polar.
b. The molecule s always nonpolar.
c. Depending on the arrangement of outer atoms, this molecule could be polar or nonpolar.

Answers

Answer 1

Answer: Depending on the arrangement of outer atoms, this molecule could be polar or nonpolar.

Explanation:

Polarity is when the electric charge that is leading to a molecule is being separated.

The polarity of SCL4F2 can either be polar or non polar and this depends on the arrangement of outer atoms. It is the arrangements of these outer atoms that'll help in the determination of its polarity.

Answer 2

The molecule SCl4F2 could be polar or nonpolar depending on the arrangement of outer atoms.

The molecule SCl4F2 could have different arrangements of outer atoms. That means that there are two possible arrangements of the molecule. Depending on which arrangement the outer Cl and F atoms have, the molecule cold be polar or nonpolar.

In the arrangement of SCl4F2  which could be polar is the one in which the dipoles in the molecule do not cancel out. In the other arrangement, the dipoles cancel out and the molecule is nonpolar.

What angle is needed to spread 4 bonds as far apart as possible?

Answers

Answer:

109°

Explanation:

According to Valence Shell Electron Pair Repulsion Theory, electron pairs on the valence shell of the central atom of a molecule must be positioned as far apart in space as possible to minimize repulsion between valence shell electron pairs.

The shape of a molecule depends on the number and type of electron pairs on the valence shell of its central atom. Lone pairs generally cause more repulsion than bond pairs of electrons.

The ideal bond angle for a molecule with four bonds is 109° which corresponds to a tetrahedral geometry. This enables the four bonds to spread as far apart in space as possible.

A 0.500 g sample of tin (Sn) is reacted with oxygen to give 0.534 g of product. What is the empirical formula of the oxide?

Answers

Answer:

[tex]Sn_2O[/tex]

Explanation:

Hello,

In this case, given the mass of the sample and mass of tin we can compute the mass of oxygen via:

[tex]m_O=0.534g-0.500g=0.034g[/tex]

Thus, by using the atomic bas of tin and oxygen we can compute their moles:

[tex]n_{Sn}=0.500gSn*\frac{1molSn}{118.8gSn} =0.00421mol\\\\n_O=0.034gO*\frac{1molO}{16gO}=0.002125mol[/tex]

Next, we need to divide both moles by the moles of oxygen as those are the smallest in order to compute the subscript in the chemical reaction:

[tex]Sn=\frac{0.00421}{0.002125}=2\\ \\O=\frac{0.002125}{0.002125}= 1[/tex]

Therefore, empirical formula of the oxide should be:

[tex]Sn_2O[/tex]

substance A is a nonpolar liquid and has only dispersion forces among its constituent particles. Substance B is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles as substance A. When substance A and substance B are combined, they spontaneously mix. Why

Answers

Explanation:

The substance A and B will mix into one solution as it is a solvent interactions which is greater than or equal to the solute- solute and the solvent-solvent interactions. Thus when such interactions occurs, it is greater or equal to the some of the other two possible interactions. And here both have the same kind of interaction, and same magnitude, so they will makes to form a solution and mixes properly and spontaneously.

Express 2.99 x 108 m/s (the speed of light) in decimal notation (i.e., express the

number without using scientific notation

Answers

Answer:

speed of light = 299,000,000 m/s

Explanation:

The speed of light in vacuum, denoted as c,  is a universal physical constant which unlike space and time, is independent of the observer. It is a constant that is important in many fields of science. Its exact value is given as 299,792,458 metres per second.

In scientific notation, it is approximately given as 2.99 x 10⁸ metres per second.

2.99 x 10⁸ metres per second = 2.99  x 100000000 = 299,000,000 m/s

Therefore, when expressed in decimal notation, the speed of light = 299,000,000 m/s.

From a 2.875 g sample containing only iron, sand, and salt, 0.660 g of iron and 1.161 g of sand were separated and recovered. What was the percent of salt in the original sample

Answers

Answer:

36.66%

Explanation:

Step 1: Given data

Mass of iron: 0.660 gMass of sand: 1.161 gMass of the sample: 2.875 gMass of salt: ?

Step 2: Calculate the mass of salt

The mass of the sample is equal to the sum of the masses of the components.

m(sample) = m(iron) + m(sand) + m(salt)

m(salt) = m(sample) - m(iron) - m(sand)

m(salt) = 2.875 g - 0.660 g - 1.161 g

m(salt) = 1.054 g

Step 3: Calculate the percent of salt in the sample

We will use the following expression.

%(salt) = m(salt) / m(sample) × 100%

%(salt) = 1.054 g / 2.875 g × 100% = 36.66%

The percent of salt in the original sample containing only iron, sand, and salt is 36.66%.

What is salt?

Salt is a mineral made up of primarily sodium chloride.

Seawater contains a vast amount of salt.

Given,

The total mass of the sample is 2.875 g

Mass of iron is  0.660 g

Mass of sand is 1.161 g

Step 1: To find the mass of salt

The total mass of the sample = the sum of the masses of the compounds

m(sample) = m(iron) + m(sand) + m(salt)

2.875 g =  0.660 g + 1.161 g + m(salt)

m(salt) = 2.875 g - 0.660 g - 1.161 g

m(salt) = 1.054 g

Step 2: Calculate the percent of salt in the sample

[tex]\%(salt) = \dfrac{m(salt) }{m(sample)} \times 100\%\\\\\\\%(salt) = \dfrac{1.054 g }{2.875 g} \times 100\% = 36.66\%[/tex]

Thus, the percentage of salt in the sample is 36.66%.

Answers

Answer:

The shape of an atom is not important so it is easier to treat atoms as spheres.

Explanation:

In considering the shape of an atom, we do not consider the shape of the orbitals individually.

Hence, we do not seek to determine the exact shape of the atom, rather we simply treat the atom as spheres. Even though most orbitals are not spherically shaped.

The density of water at 40°C is 0.992 g/mL. What is the volume of 2.69 g of water at this temperature? V= mL​

Answers

Answer:

[tex]\boxed {\tt 2.71169355 \ mL}[/tex]

Explanation:

Density can be found using the following formula:

[tex]d=\frac {m}{v}[/tex]

Rearrange the formula for v. Multiply both sides by v, then divide both sides by d.

[tex]d*v =\frac {m}{v}*v[/tex]

[tex]d*v=m[/tex]

[tex]\frac{d*v}{d}=\frac{m}{d}[/tex]

[tex]v=\frac{m}{d}[/tex]

The volume can be found by dividing the mass by the density. The mass is 2.69 grams and the density is 0.992 grams per milliliter.

[tex]m= 2.69 \ g\\d= 0.992 \ g/mL[/tex]

Substitute the values into the formula.

[tex]v=\frac{2.69 \ g}{0.992 \ g/mL}[/tex]

Divide. Note that the grams, or g, will cancel each other out.

[tex]v=\frac{2.69}{0.992 \ mL}[/tex]

[tex]v= 2.71169355 \ mL[/tex]

The volume of the water is 2.71169355 milliliters.

A peregrine falcon dives 176 meters through the air in 8 seconds. Its
average speed during the dive is 22 m/s. *

Answers

Answer:

This question is asking to find the average speed during the dive. The answer is 22m/s.

Explanation:

Average speed of a substance can be calculated knowing it's distance over a particular amount of time.

The formula for average speed is:

Average speed (s) = Distance (d) / time (t)

In the case of this question where A peregrine falcon dives 176 meters through the air in 8 seconds, the distance of the falcon is 176m, while the time is 8s. Hence;

Average speed = 176/8

Average speed = 22

Therefore, the average speed of the falcon diver is 22m/s.

What is element?

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

Fireworks has many different types of element. When any element is given an energy. Then the process of excitation of electrons takes place from its outermost shells. Every element absorb characteristic wavelength of energy and releases light to the corresponding wavelength.

Therefore, energy is the only factor that  determines the color of light of fireworks.
