Answer: Diamond is covalent crystal. It has the highest melting point because high energy covalent bonds hold the crystal together.

Explanation: Covalent bonds are very strong, so covalent network solids typically have the highest melting points out of all four types of solids.

Answer:

giant covalent solids

Ionic solids also have high melting points, often over 1000 degrees but they can vary. Some are often low enough to melt in the lab with a Bunsen burner:

Answer:

C.

Explanation:

The molecules in hot air are moving faster than the molecules in cold air. Because of this, the molecules in hot air tend to be further apart on average, giving hot air a lower density. That means, for the same volume of air, hot air has fewer molecules and so it weighs less.

How is hotter air different than colder air?

Option C :- In hotter air, the molecules are farther apart and moving more rapidly.

causing the particles to move faster and farther apart.

Explanation:

As the kinetic energy possessed by the particles of matter increases and so does the distance, hence particles tend to move faster.

Kinetic energy is "a form of energy that an object or a particle has by reason of its motion".

Particle is "a small portion of matter".

What is matter?

Matter is "anything that occupies space and has mass".

What is distance?

Distance of "an object can be defined as the complete path travelled by an object".

Hence, the kinetic energy of particles of matter increases with the increase in the distance between the particles.

Explanation:

As the earth revolves around the sun, and the moon revolves around the earth, the intensity of sunlight hitting the moon changes over time. This explains why we get the phases of the moon. The answer as to why, is because the moon was moving towards a state of being a "full moon."

Answer:

78.68g Na

121.32 Cl

Explanation:

This one is more easy than the wording makes it seem. Since there are 60.66g of sodium (Na) and 39.34g of Chlorine (Cl) it adds up to 100g, so in this case you can just double each amount, and get what each would be in a 200g sample.

Answer:

It is equal to the number of moles of acid that reacted. When Oxalic acid is your limiting reactant it is the # of moles of oxalic acid used. When NaOH is your limiting reactant it is equal to the number of moles of NaOH used.

The  moles of OH⁻ that reacted in the titration can be found by;

The moles of OH⁻ used in the titration experiment is dependent on the number of moles of the limiting reactant, used during the Titration in the laboratory.  

From the data contained in the table, the limiting reactant is the oxalic acid. therefore the number of moles of OH⁻ is equal to the number of moles of oxalic acid used during titration.

Hence we can conclude that the  moles of OH⁻ that reacted in the titration can be found by determining the number of moles of oxalic acid used in the titration

Answer:

1.9 x 10⁻¹³M

Explanation:

Given 0.027M Ca(OH)₂(aq) => 0.027M Ca⁺²(aq) + 2(0.027M) OH⁻(aq)

2(0.027M) OH⁻(aq) = 0.054M OH⁻(aq).

from [H⁺][OH⁻] = 1 x 10⁻¹⁴ at STP Conditions (0°C, 1Atm)

∴{H⁺] = [H₃O⁺] = (1 x 10⁻¹⁴/0.054)M = 1.85 x 10⁻¹³M or 1.9 x 10⁻¹³at 0°C & 1Atm pressure.

Considering the definition of polar molecule, Br has a negative partial charge and H a ​​positive partial charge.

The bond dipole moment can then be defined as the magnitude of the polarity in a bond. This moment represents the distribution of electron density in a bond.

The distribution of charges is due to the fact that the atoms that form them have different electronegativity, in such a way that when a covalent bond is created and the electrons are shared, the electrons of the bond are attracted with different force by the atoms that share them.

Then, a polar molecule is one that is neutral, that is, it does not have a net charge. But it has an internal distribution of charges that form a partially positive region and a partially negative region.

That is, polar bonds are established between atoms of different electronegativity, so that the atom with higher electronegativity will attract the electrons towards itself, giving rise to two opposite charges in the bond and  creating a negative charge on the atom because the electrons have negative charge.

In this way, in a polar molecule there is separation between positive and negative charges. The bonds will be the more polar the greater the electronegativity difference between the bonded atoms.

In this case,  bromine Br has a higher electronegativity and attracts electrons shared with hydrogen H more strongly. Then Br has a negative partial charge and H a ​​positive partial charge.

The age of the rock can be calculated from the half life of Uranium - 238. The age of the rock sample is 9 million years.

The term radioactivity refers to the sponteanous decay of a material which leads to the production of daughter nuclei. We know that uranium 238 decays to lead 206  with a half life of 4.5 billion years.

Using;

0.693/t1/2 = 2.303/t log(No/N)

t1/2 = half life of uranium 238

t = age of the rock sample

No = initial amount of uranium 238

N = amount of uranium 238 after time t

Now;

0.693/4.5 * 10^9 = 2.303/t log (No/0.25No)

0.693/4.5 * 10^9 = 2.303/t log(1/0.25)

0.693/4.5 * 10^9 =1.387/t

1.54 * 10^-10 = 1.387/t

t =  1.387/1.54 * 10^-10

t = 9 million years

The age of the rock sample is 9 million years.

Answer:

only certain wavelengths of the light can be absorbed.

There are no transitions in the hydrogen atom that corresponds to the wavelength of yellow or orange light.

Each color corresponds to a particular wavelength. The wavelengths that are observed for a given atom depends on the transitions that are possible for electrons of the atom.

In the hydrogen atom, there is no transition whose wavelength corresponds to the wavelength of yellow or orange light. None of the lines in the hydrogen spectrum has such wavelength.

For instance, yellow light corresponds to 590 nm - 560 nm but this wavelength is missing from the spectrum of hydrogen(crosscheck in the image attached).

As such, we do not see yellow or orange lights in the hydrogen spectrum.

[tex][H_2]_{eq}=0.183M[/tex]

[tex][I_2]_{eq}=0.183M[/tex]

[tex][HI]_{eq}=0.025M[/tex]

Explanation:

Hello.

In this case, for this equilibrium problem, we first realize that at the beginning there is just HI, it means that the reaction should be rewritten as follows:

[tex]2HI\rightleftharpoons H_2+I_2[/tex]

Whereas the law of mass action (equilibrium expression) is:

[tex]Kc=\frac{[H_2][I_2]}{[HI]^2}[/tex]

That in terms of initial concentrations and reaction extent or change [tex]x[/tex] turns out:

[tex]Kc=\frac{x*x}{([HI]_0-2x)^2}\\\\54.3=\frac{x^2}{(0.391M-2x)^2}[/tex]

And the solution via solver or quadratic equation is:

[tex]x_1=0.183M\\\\x_2=0.210M[/tex]

Whereas the correct answer is 0.183 M since the other value yield a negative concentration of HI at equilibrium (0.391-2*0.210=-0.029M).This, the equilibrium concentrations are:

[tex][H_2]_{eq}=0.183M[/tex]

[tex][I_2]_{eq}=0.183M[/tex]

[tex][HI]_{eq}=0.391M-2*0.183M=0.025M[/tex]
