Answer 2

The plate is moving away from me in the figure of volcanoes. Therefore, the correct option is B.

What are volcanoes?

Volcanoes are geological formations that form when magma, ash, and other elements erupt from beneath the Earth's surface. Both on land and in water, they come in a wide variety of shapes and sizes. Volcanoes often develop along the boundaries of tectonic plates or at "hot spots" where plumes of hot mantle flow upward from the Earth's core and are associated with tectonic activity.

Volcanic eruptions can cause a variety of hazards, such as waves, pyroclastic flows, ash clouds, and lava flows. Volcanoes can be devastating, but they can also create new areas and provide healthy soil, which benefits the ecology.

Therefore, the correct option is B.

Uranium hexafluoride is a solid at room temperature, but it boils at 56C. Determine the density of uranium hexafluoride at 60.C and 745 torr.

Answers

Answer: The density of Uranium Hexafluoride at 60 °C and 745 torr is 0.0127 g/ml

Explanation:

Uranium Hexafluoride is only present as gas at 60 °C and 745 torr.

So, we know PV = nRT, from that

n/V = P/ RT = (745 torr)/(62.36 L-torr/mol*K)(337 K) = 0.0354 mol/L.

Density = (352.02 g/mol)(0.0354 mol/L)/(1000 cm³/L) = 0.0127 g/cm³

Answers

In a mass spectrometer, the ion with the highest abundance in the mass spectrum that is assigned a relative abundance of 100% is referred to as the base peak.

What does a mass spectrum base peak represent?

The base peak is the greatest peak in the mass spectrum that corresponds to the most prevalent ion or the strongest peak in the spectrum. It could be the parent peak or a fragment ion peak, depending on the type of molecule. Sometimes the base peak may be the molecular ion peak.

What does a spectrophotometer's base peak mean?

The base peak, which is the peak with the highest intensity in the spectrum, is given a value of 100 percent, and the intensities of the other peaks, including the molecular ion peak, are expressed as a percentage of the base peak (height x sensitivity factor). In addition to producing positive ions, bombarding a sample with electrons can also produce negative ions.

What is a redox reaction?

Redox reactions, also known as oxidation-reduction reactions, involve the simultaneous oxidation and reduction of two different reactants.

The Half-Equation Method is one technique used to balance redox processes. The equation is divided into two half-equations using this technique: one for oxidation and one for reduction.

By changing the coefficients and adding [tex]H_{2}O[/tex], [tex]H^{+}[/tex], and [tex]e^{-}[/tex] in that order, each reaction is brought into equilibrium:

By putting the right number of water ([tex]H_{2}O[/tex]) molecules on the other side of the equation, the oxygen atoms are brought into balance.By adding [tex]H^{+}[/tex] ions to the opposing side of the equation, one can balance the hydrogen atoms (including those added in step 2 to balance the oxygen atom).Total the fees for each side. Add enough electrons ([tex]e^{-}[/tex]) to the more positive side to make them equal. (As a general rule, [tex]e^{-}[/tex] and  [tex]H^{+}[/tex]are nearly always on the same side.)The [tex]e^{-}[/tex] on either side must be made equal; if not, they must be multiplied by the lowest common multiple (LCM) in order to make them equal.One balanced equation is created by adding the two half-equations and canceling out the electrons.

Answers

The concentration of acetic acid:

The concentration of the acetic acid before titration is 0.128 M

What is titration?

Titration is a quantitative analytical procedure that works by allowing a known analyte to gradually react with a titrant until an endpoint is reached.

Titration for weak acid and strong base:

Moles of acetic acid =  moles of NaOH

Given:

Concentration of NaOH = 0.1067 M

Volume of NaOH = 30.07 ml = 0.03007 L

Calculation:

So, by using the formula, Concentration = Moles/Volume

Moles of NaOH = concentration x volume = 0.1067 x 0.03007 = 0.0032

Therefore, the moles of acetic acid  = 0.0032 mole

Now, using the formula again for determining the concentration of acetic acid, we get,

Silver bromide is the photosensitive material in 35 mm photographic film. When monochromatic light falls on film, the photons are recorded if
they contain sufficient energy to react with silver bromide in the film. The minimum energy needed to do this is approximately 57.9 kJ/mol. What
is the wavelength of this energy in nm?

Answers

The minimum energy needed by the photons to react with silver bromide in the film is approximately 57.9 kJ/mol. Then, the wavelength is 206 nm.

What is wavelength?

Wavelength of a wave is the distance between two consecutive crests or troughs of the wave.

To find the wavelength of the energy in nm, we can use the equation:

E = hc/λ

where E is the energy in joules, h is Planck's constant (6.626 x 10⁻³⁴ J s), c is the speed of light (2.998 x 10⁸ m/s), and λ is the wavelength in meters.

First, we need to convert the energy from kJ/mol to J/photon:

57.9 kJ/mol = 57.9 x 1000 J/mol / 6.02 x 10²³ mol^-1

= 9.626 x 10²⁰ J/photon

Now we can use the equation above to find the wavelength:

9.626 x 10²⁰ J/photon = (6.626 x 10⁻³⁴ J s)(2.998 x 10⁸ m/s) / λ

Solving for λ, we get:

λ = hc/E = (6.626 x 10⁻³⁴ J s)(2.998 x 10^8 m/s) / 9.626 x 10⁻²⁰J/photon

  = 2.06 x 10⁻⁷ m

Finally, we convert the wavelength from meters to nanometers:

λ = 2.06 x 10⁻⁷ m x (10⁻⁹ nm/m)

  = 206 nm

Therefore, the wavelength of the energy needed to react with silver bromide in 35 mm photographic film is approximately 206 nm.

Which law was used to determine the relationship between the volume and the number of moles in this equation?
Boyle’s law
Charles’s law
Avogadro’s law
Gay-Lussac’s law

Answers

C. The law that was used to determine the relationship between the volume and the number of moles is Avogadro’s law.

What is Avogadro’s law?

Avogadro's law states that equal volumes of any gas contain the same number of molecules at the same temperature and pressure.

V ∝ n

where;

V is volume of the gasn is number of moles

Thus, the law that was used to determine the relationship between the volume and the number of moles is Avogadro’s law.

Answer: C. Avogadro’s law

Explanation:

In each of the following substances nah, h2, and h2s, hydrogen is assigned an oxidation number of +1. is this correct? explain your reasoning

Answers

No It is not correct.

Correct oxidation number of hydrogen in  NaH,H2 and H2S are:

Let x be the Oxidation state of ’H’  by oxidation state rule.

        x+1 =0 (Sodium has +1 Oxidation state )

        x=−1

        Therefore, -1 is oxidation number of Hydrogen in NaH.

The oxidation number of an element's atom in its standard state is zero. As a result, the oxidation number for H2 is zero.The hydrogen oxidation number in H2 is +1. As a result, that hydrogen atom can be reduced to lower oxidation states of hydrogen, such as 0 and -1. However, because +1 is the highest oxidation state of hydrogen, the hydrogen atom cannot be reduced any further.What is oxidation number?

In simple terms, the oxidation number is the number assigned to elements in a chemical combination. The oxidation number is the number of electrons that atoms in a molecule can share, lose, or gain when forming chemical bonds with atoms of a different element.

\You earn $1,300 working at a summer job. You decide to put it into an account and leave it there for four years while you are in college. The principal will earn 1.5% simple interest. How much will you have in your account at the end of four years You apply a force on an object that is 100 times its mass. The acceleration of the object will be 100m/s^2. After a while, it perpendicularly hits another object with a mass 10 times smaller than the first object. When they collide, in theory, the momentum of the first object will all get transferred into the small object. And that means, the heavy object will completely be at rest, while the smaller object will have a force applied to it by the big object equal to ma. In real life, it seems that when two objects collide, the bigger object doesnt completely stop and just pushes the smaller or the same massed object. In real life, it seems that when the collision happens, the first object continues moving towards the other object, and doesnt completely get at rest right after the collision. Why is that?
