Which of the following has a nonpolar bond? *

HCI
NH3
CH4

Answer:

0.56 mL

Explanation:

Methane gas and chlorine gas react to form hydrogen chloride gas and carbon tetrachloride gas. What volume of carbon tetrachloride would be produced by this reaction if 1.1 mL of chlorine were consumed.

Step 1: Write the balanced equation

CH₄(g) + 2 Cl₂(g) → CCl₄(g) + 4 HCl (g)

Step 2: Calculate the moles corresponding to 1.1 mL of Cl₂

At standard temperature and pressure, 1 mole of a gas has a volume of 22.4 L.

1.1 × 10⁻³ L × 1 mol/22.4 L = 4.9 × 10⁻⁵ mol

Step 3: Calculate the moles of CCl₄ formed from 4.9 × 10⁻⁵ moles of Cl₂

The molar ratio of Cl₂ to CCl₄ is 2:1. The moles of CCl₄ are 1/2 × 4.9 × 10⁻⁵ mol = 2.5 × 10⁻⁵ mol.

Step 4: Calculate the volume corresponding to 2.5 × 10⁻⁵ moles of CCl₄

At standard temperature and pressure, 1 mole of a gas has a volume of 22.4 L.

2.5 × 10⁻⁵ mol × 22.4 L/mol = 5.6 × 10⁻⁴ L = 0.56 mL

Answer:

[tex]M=0.16M[/tex]

Explanation:

Hello!

In this case, since the molarity is defined as moles of solute divided by liters of solution, since we have phenol with a molar mass of 94.12 g/mol, we can first compute the moles in 1.5 g of phenol:

[tex]n=1.5g*\frac{1mol}{94.12 g}=0.016mol[/tex]

Next, since 1000 mL = 1 L, we notice that the volume of the solution is 0.100 L and therefore, the molarity of such solution turns out:

[tex]M=\frac{n}{V}=\frac{0.016mol}{0.100L}\\\\M=0.16M[/tex]

Heat is a form of energy and transfer of it takes place from hotter body to cooler body.

Heat transfer is a process in which heat transfers from one object to another object without any loss.

Heat transfer is a branch of thermal engineering that deals with the production, use, conversion, and transfer of thermal energy between physical systems.

Transfer of heat generally takes place from hotter body to the cooler body till when both the bodies gain the same temperature.

Hence heat transfers from hotter body to cooler body.

Answer:

The answer is Option a, that is "−9kJmole,5kJmole".

Explanation:

Please find the complete question in the attached file.

In the question, it uses the catalyst inside a process, which does not modify the process eigenvalues, however, it decreases the active energy with an enthalpy of -9kJmole, and also the power for activating decreases around 13 to 5 kJ mole, that's why the choice a is correct.

Hello!

In this case, since the decomposition of potassium chlorate is:

[tex]2KClO_3\rightarrow 2KCl+3O_2[/tex]

We can see a 2:3 mole ratio between potassium chlorate and oxygen (molar mass 32.0 g/mol), thus, via stoichiometry, we compute the mass of oxygen that are produced by the decomposition of 2.50 moles of this reactant:

[tex]m_{O_2}=2.50molKClO_3*\frac{3molO_2}{2molKClO_3} *\frac{32.0gO_2}{1molO_2}\\\\m_{O_2}=120gO_2[/tex]

Answer:

C

Explanation:

Answer and Explanation:

For the following balanced reaction:

PCl₅(g) ↔ PCl₃(g) + Cl₂(g)

We can see that all reactants and products are gases, so it is an homogeneous equilibrium. The expression for the equilibrium constant Kp can be written from the partial pressures (P) of reactants and products as follows:

[tex]Kp=\frac{(P PCl_{3})(P Cl_{2})}{(P PCl_{5})}[/tex]

Where PPCl₃ is the partial pressure of PCl₃ (reactant), PCl₂ is the partial pressure of Cl₂ (reactant) and PPCl₅ is the partial pressure of PCl₅ (product).

The subscript 2 indicates number of Cl atoms

The molecular formula shows the number of atoms of a compound

whereas the empirical formula is the simplest comparison of the atoms making up the compound

MgCl₂ is an ionic compound composed of Mg and Cl atoms

Mg is in group 2 which has a +2 charge, while Cl is in the Halogen group which has a charge of -1

If the two are bonded, the 2 electrons released by Mg will be bound by 2 Cl atoms, each of which atoms of Cl need 1 more electron in order to obtain a stable electron configuration such as a noble gas

So the number 2 in the MgCl compound indicates the number of Cl atoms

Explanation:

Answer:

Explanation:

average kinetic energy of a gas molecule really only depends on the temperature, so which ever container is at the highest temperature is the answer

In comparison to other fundamental states of matter, plasma has the highest kinetic energy. This is due to the fact that particles in a plasma travel more quickly than those in a corresponding solid, liquid, or gas.

The energy that an object has as a result of motion is known as kinetic energy. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

The reason why molecules in gases have the largest kinetic energy is because they have more space between one another, experience less intermolecular force, and travel at a faster rate, which results in higher energy.

The temperature has a direct impact on the average kinetic energy of the particles inside a container.

Thus, In comparison to other fundamental states of matter, plasma has the highest kinetic energy.

The visible light with a wavelength of 4.7x10^-7 meters will have a frequency of 0.67 × 10¹⁵ Hz.

The term wavelength is defined as the distance between two successive crest and two successive trough. Wave length is represented by the symbol "λ" (lambda). The formula of wavelength is given by equation as follows:

λ = ν × f

So, the distance between either one crest or trough of one wave and the next wave is known as wavelength.

Wavelength relates to frequency as follows:

λ = ν × f

Where,

λ = Wavelength of light

ν = speed of light

f = frequency of light

We have

λ = 4.7x10^-7 meters

F = ?

ν = 3 × 10⁸ m/s

By substituting this values in given equation we get,

λ = ν × f

f = 3 × 10⁸ / 4.7x10^-7

f = 0.67 × 10¹⁵ Hz

Thus, visible light with a wavelength of 4.7x10^-7 meters will have a frequency of 0.67 × 10¹⁵ Hz.

Answer:

3.43×10¹ mol

Explanation:

Given data:

Initial number of  moles = 12.4 mol

Initial volume = 122.8 L

Final volume = 339.2 L

Final number of moles = ?

Solution:

The number of moles and volume are directly proportional to each other at same temperature and pressure.

Formula:

V₁/n₁  =  V₂/n₂

Now we will put the values,

122.8 L/ 12.4 mol  =  339.2 L / n₂

n₂ = 339.2 L× 12.4 mol  / 122.8 L

n₂ = 4206.08 L.mol /122.8 L

n₂ = 34.3mol

Answer: A and D

Explanation:

Answer: D) Nitrogen Dioxide

Explanation:

The characteristics of moles allow you to find that the correct answer for which sample weighs more is:

             D) Nitrogen Dioxide

The molecular weight of the substance is the weight of one mole of a material, where one mole is Avogadro's number of particles.

In all chemical reactions the relationships are given as a function of moles.

Let's find the molecular weight of each of the substances, we take the atomic weights from the periodic table

Element      PA (gr / mol)

   H                     1

   C                   12

   N                   14

   O                   16

   Ar                  40

A) Ammonia with NH₃ formula

     weight of a mole of molecules

           MP = 14 + 3

           PM = 17 gr / mol

B) Argon symbol Ar

    It is a noble gas and does not react

         PM = 40 gr / mol

C) Carbon dioxide formula CO₂

      Weight per mole of substance

        PM = 12 + 2 16

        Pm = 44 gr / mol

D) Nitrogen dioxide formula NO₂

       Weight per molecular

         MP = 14 + 2 16

         PM = 46 gr / mol

E) Oxygen symbol O formula O₂

      Molecular weights

         PM = 2 16

         PPM = 32 gr / mol

It indicates that we have two liters of sample, so the number of moles of each substance is the same, therefore the substance that weighs more is Nitrogen Dioxide (NO₂)

When reviewing the different answer, the correct one is:

            D) Nitrogen Dioxide

Answer:

A. (CH3)3C-I reacts by SN1 mechanism whose rate is independent of nucleophile reactivity.

Explanation:

We must recall that (CH3)3C-I is a tertiary alkyl halide. Tertiary alkyl halides preferentially undergo substitution reaction via SN1 mechanism.

In SN1 mechanism, the rate of reaction depends solely on the concentration of the alkyl halide (unimolecular mechanism) and is independent of the concentration of the nucleophile. As a result of this, both Br^- and Cl^- react at the same rate.
