Which is a characteristic of nuclear fusion?

The answer is:

Hence, the new pressure will be 2.07 atm.

[tex]P_{2}=2.07atm[/tex]

Since we know that the gas is inside of a rigid container, meaning that the volume will be kept constant, we can solve the problem using the Gay-Lussac's Law.

The the Gay-Lussac's Law establishes that when an ideal gas is kept at the same volume, the pressure and the temperature will be proportional.

We need to pay special attention when we are working with the Gay-Lussac's Law since its equaitons works with absolute temperatures (Kelvin ), so, if we are working with relative temperatures such as Celsius degrees or Fahrenheit degrees, we need to convert the temperatures to Kelvin.

We can convert from Celsius degrees to Kelvin using the following formula:

[tex]Temperature(K)=Temperature(C\°)+273[/tex]

So, we have the Gay-Lussac's equation:

[tex]\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}[/tex]

Also, we are given the following information:

[tex]T_{1}=30\° \\P_{1}=2atm\\T_{2}=40\°[/tex]

Therefore, converting the temperature to Kelvin, we have:

[tex]T_{1}=30C\°=30+273K=303K\\\\T_{1}=40C\°=40+273K=313K\\[/tex]

Now, calculating we have:

[tex]\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}[/tex]

[tex]P_{2}=\frac{P_{1}}{T_{1}}*T_{2}\\\\P_{2}=\frac{2atm}{303K}*313K=2.07atm[/tex]

Hence, the new pressure will be 2.07 atm.

[tex]P_{2}=2.07atm[/tex]

This are some of the transuranium elements:

Neptunio - 93

Plutonium - 94

Americium - 95

Answer:

1. 2.8 moles of H₂

2. 7.38 moles of CO₂

3. 5.3 moles of O₂

4. 7.4 moles of KNO₃

Explanation:

Here are the steps to doing this:

1. Write the chemical equation of each reaction.

2. Balance the equation.

3. Find out the ratio between reactant and product

4. Determine the actual yield of your reactants.

5. The amount of product produced is determined by how much product the limiting reactant produces.

Let's do this!

1. Given: 3.4 moles of Magnesium(Mg) and 5.6 moles of Hydrochloric acid (HCl)

Equation:

Mg + 2HCl → MgCl₂ + H₂

Reactant to Product ratio

1 mole of Mg produces 1 mole of H₂      [tex]\dfrac{1moleof Mg}{1mole of H_{2}}[/tex]

2 moles of HCl produces 1 mole of H₂  [tex]\dfrac{2molesofHCl}{1mole of H_{2}}[/tex]

Determine actual yield of reactants

[tex]3.4moles of Mg\times\dfrac{1moleofH_2}{1moleofMg}=3.4molesofH_{2}\\\\5.6moles ofHCl\times\dfrac{1moleofH_2}{2moleofHCl}=2.8molesofH_{2}[/tex]

Since 5.6 moles of HCl can only produce 2.8 moles of H₂, before it is used up, then this means that that is all the product this reaction can produce.

2. Given: 3.4 moles of C₃H₈ and 12.3 moles of oxygen gas (O₂)

Equation:

C₃H₈  +  5O₂ → 3CO₂ + 4H₂O

Reactant to Product ratio

1 mole of C₃H₈ produces 3 moles of CO₂      [tex]\dfrac{1moleofC_{3}H_{8}}{3molesofCO_{2}}[/tex]

5 moles of O₂ produces 3 moles of CO₂       [tex]\dfrac{5molesofO_{2}}{3moleofCO_{2}}[/tex]

Determine actual yield of reactants

[tex]3.4molesofC_{3}H_{8}\times\dfrac{3molesofCO_{2}}{1moleofC_{3}H_{8}}=10.2molesofH_{2}[/tex]

[tex]12.3molesofO_{2}\times\dfrac{3molesofCO_{2}}{5molesofO_{2}}=7.38molesofCO_{2}[/tex]

The answer is then 7.38 moles of CO₂

**3. 5.3 moles of H₂O

This one is a little bit different. It is asking how much of a reactant is needed to produce the amount of product given. For this, just write a balanced equation for the reaction and get the ratio of reactant to product and solve for the actual yield. Since it is only asking for oxygen gas, you just need to do that one.

Equation:

CH₄  + 2O₂ → CO₂ + 2H₂O

Reactant to Product ratio

[tex]\dfrac{2molesofO_{2}}{2molesofH_{2}O}=\[tex]7.88molesofKI\times\dfrac{1moleofKNO_{3}}{1moleofKI}=7.88molesofKNO_{3}[/tex]

Actual yield:

[tex]5.3molesofH_{2}O\times\dfrac{1moleofO_{2}}{1moleofH_{2}O}=5.3molesofO_{2}[/tex]

The answer is 5.3 moles of O₂.

4. 3.7 moles of Lead (II) Nitrate (Pb(NO₃)₂) and 7.8 moles of Potassium Iodide (KI)

Equation:

Pb(NO₃)₂ + 2KI → PbI₂ + 2KNO₃

Reactant to Product ratio

[tex]\dfrac{2molesofKI}{2molesofKNO_{3}}=\dfrac{1moleofKI}{1moleofKNO_{3}}[/tex]

[tex]\dfrac{1molesofPb(NO_{3})_{2}}{2molesofKNO_{3}}[/tex]

Actual yield:

[tex]3.7molesofPb(NO_{3})_{2}\times\dfrac{2molesofKNO_{3}}{1moleofPb(NO_{3})_{2}}=7.4molesofKNO_{3}[/tex]

The answer is 7.4 moles of KNO₃.

Explanation:

The flowchart shows the order of the common states of matter as solids, liquids, and gases. To find the properties that match this order, let's examine each option:

1. Space between particles: This property refers to the distance between particles in a substance. In solids, particles are tightly packed together, so there is less space between them. In liquids, particles are less tightly packed, so there is more space between them compared to solids. In gases, particles are very spread out, so there is the most space between them. Therefore, this property matches the order of the states of matter in the flowchart.

2. Kinetic energy of particles: Kinetic energy refers to the energy of motion. In solids, particles have the least amount of kinetic energy as they vibrate in fixed positions. In liquids, particles have more kinetic energy as they move more freely, but still stay close together. In gases, particles have the most kinetic energy as they move rapidly and spread out. Therefore, this property also matches the order of the states of matter in the flowchart.

3. Density of matter: Density refers to the mass of a substance per unit volume. While the density of matter does change between the different states, it does not match the order of the states of matter in the flowchart. Solids can have a higher density than liquids, and liquids can have a higher density than gases. So, this property does not match the order shown in the flowchart.

4. Speed of particle motion: The speed of particle motion does change between the different states, but it does not match the order of the states of matter in the flowchart. The particles in solids have the slowest motion, followed by particles in liquids, and then particles in gases which have the fastest motion. So, this property does not match the order shown in the flowchart.

In summary, the properties of matter that match the order of the states of matter in the flowchart are the "space between particles" and the "kinetic energy of particles." These properties help explain the differences between solids, liquids, and gases based on how closely packed the particles are and how much they are moving.

The order of the states of matter in the flowchart is related to the space between particles and the speed of particle motion.

The flowchart represents the order of the three common states of matter: solids, liquids, and gases. As we move from solids to liquids to gases, the space between particles increases. In solids, the particles are closely packed together, whereas in liquids, the particles have some space between them, and in gases, the particles are widely spaced apart. Likewise, the speed of particle motion increases as we move from solids to liquids to gases. In solids, the particles are tightly packed and vibrate in place, in liquids, the particles move more freely and are able to slide past each other, and in gases, the particles move rapidly and randomly in all directions.

However, the density of matter does not follow the same order as the flowchart. The density of a substance depends on the mass and volume, and it can vary greatly between different substances in the same state of matter. For example, the density of lead (a solid) is much higher than the density of water (a liquid).

The kinetic energy of particles is also not directly related to the order of the states of matter in the flowchart. The kinetic energy of particles is a measure of their motion, and it can vary within the same state of matter depending on the temperature. For instance, the kinetic energy of the particles in boiling water (a liquid) is higher than that in cold water (also a liquid).

A. the amount of water is a constant (aka independent variable)

The amount of water is constant in the Jarrett in each of the three identical containers experiment.

The temperature at which a liquid boils and turns to vapour.

The water molecules need more energy to produce enough pressure to escape the boundary of the liquid.

The more salt (or any solute) added to water, the more you raise the boiling point.

When the ionic compound salt is added to the equation, it lowers the freezing point of the water.

Salt molecules block water molecules from packing together when the temperature is lowered.

It then prevents them from becoming ice. More water molecules leave the solid phase than the ones entering the solid phase.

As defined by Arrhenius:

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H+). In other words, an acid increases the concentration of H+ ions in an aqueous solution. This protonation of water yields the hydronium ion (H3O+); in modern times, H+ is used as a shorthand for H3O+ because it is now known that a bare proton (H+) does not exist as a free species in aqueous solution.

An Arrhenius base is a substance that dissociates in water to form hydroxide (OH–) ions. In other words, a base increases the concentration of OH– ions in an aqueous solution.

Explanation:

One way to calculate the lattice energy is to use Hess's Law .

The lattice energy U is the energy released when the gaseous ions combine to form a solid ionic crystal:

M²⁺(g) + 2X⁻(g) ⟶ MgX₂(s); U = ?

We must generate this reaction rom the equations given.

(1) M(s) + X₂ (g) ⟶ MX₂(s);      ΔHf⁰ = -985 kJ·mol⁻¹

(2) M(s) ⟶ M(g);                  ΔHsub =   135 kJ·mol⁻¹

(3) M(g) ⟶M⁺(g) +e⁻                   IE₁ =   731 kJ·mol⁻¹

(4) M⁺(g) ⟶ M²⁺(g) + e⁻             IE₂ = 1403 kJ·mol⁻¹

(5) X(g) + e⁻ ⟶ X⁻(g)                 EA =  -335 kJ·mol⁻¹

(6) X₂(g) ⟶ 2X(g)                      BE =   207 kJ·mol⁻¹

Now, we put these equations together to get the lattice energy.  Underlined species have been cancelled.

                                                        E/kJ  

(7)   M²⁺(g) + e⁻⟶ M⁺(g)                 -1403

(8)   M⁺(g) + e⁻ ⟶ M(g)                     -731

(9)   M(g) ⟶ M(s)                              -135

(10) M(s) + X₂(g) ⟶ MX₂(s)              -985

(11)  2X(g) ⟶ X₂(g)                           -207

(12) 2X⁻(g) ⟶ 2X(g) + 2e⁻               +670

     M²⁺(g) +  2X⁻(g) ⟶ MX₂(s)       -2791

The lattice energy of MX₂ is [tex]\boxed{\textbf{-2791 kJ/mol}}[/tex].

The lattice energy of the ionic compound MX2 can be calculated using the Born-Haber cycle. This accounts for various steps including the sublimation, ionization, dissociation, and electron affinity of the involved elements. In this case, the lattice energy of MX2 is 2633 kJ/mol.

The lattice energy of an ionic compound, in this case MX2, can be calculated using the Born-Haber cycle - a thermochemical cycle involving several steps where every step corresponds to a specific energy change.

The steps include: sublimation of the metal, ionization of the metal, dissociation of the halogen, addition of electrons to the halogen atoms (electron affinity), and formation of the ionic compound.

For this case, you can calculate the lattice energy of MX2 by adding the enthalpy of formation, enthalpy of sublimation, ionization energies, electron affinity (multiplied by 2 as there are 2 halogens per formula unit in MX2), and half of the bond energy (as we are breaking one X2 into two X per formula unit of MX2).

So, the lattice energy = |Δ∘f + Δsub + IE1 + IE2 + 2(ΔEA) + 0.5(BE)|.

Which gives = |-(-985 kJ/mol) + 135 kJ/mol + 731 kJ/mol + 1403 kJ/mol + 2*(-335 kJ/mol) + 0.5*207 kJ/mol| =  2633 kJ/mol. Therefore, the lattice energy of MX2 is 2633 kJ/mol.

Explanation

The physical properties of a solution are not affected by the concentration of the components.

Boiling points and freezing points of solutions change as the concentration of the solute changes.

Moles of solute = (Liters of solution) x (Molarity of solution)

(Initial Concentration)(Initial Volume) = (Final Concentration) (Final Volume)

Concentration affects if an acid is weak or strong.

Answer : All the given options are applicable for a solution’s concentration.

Explanation :

(1) The physical properties of a solution are not affected by the concentration of the components.

This statement is apply to a solution's concentration. Physical properties can be measured without changing the composition of substance. For example : The boiling point of 2 gram substance and 10 grams of substance  will always remain same.

(2) Boiling points and freezing points of solutions change as the concentration of the solute changes.

This statement is apply to a solution's concentration. As we know that the boiling and freezing point of solution depends on the number of moles of solute or concentration of solute. So, as the concentration of solute changes the boiling and freezing point of solution.

(3) Moles of solute = (Liters of solution) x (Molarity of solution)

This statement is apply to a solution's concentration. As we know that the molarity is defined as the number of moles of solute present in one liter of volume of solution.

(4) (Initial Concentration)(Initial Volume) = (Final Concentration) (Final Volume)

This statement is apply to a solution's concentration as per dilution law.

(5) Concentration affects if an acid is weak or strong.

This statement is apply to a solution's concentration. As the concentration of an acid and base is the amount of moles of solute per unit volume. That means if a solution has higher molarity, then the concentration is also higher and vice-versa.

Hence, all the given options are applicable for a solution’s concentration.

Explanation:

Energy transfer in waves involves a disturbance that propagates through a medium, causing particle oscillation and energy transmission. For example, sound waves transfer energy through air via compression and expansion of air molecules. Waves do not move the particles but rather transfer energy through them.

Energy transfer in waves involves the propagation of a disturbance through a medium. This disturbance causes particles of the medium to move away from their equilibrium position, transferring energy from one particle to the next. This transfer occurs as the wave travels through the medium, causing the particles to oscillate back and forth.

For example, in acoustics, energy is transferred via vibrational waves. When a sound wave travels through the air, it compresses and expands air molecules, creating pressure variations that propagate through the medium as a longitudinal wave. These oscillations result in a transfer of energy from the source of the sound to the receiver.

Generally, a wave does not transport the particles of the medium over a distance, but it does transmit energy and momentum. Key characteristics of waves include a disturbance in space and time and a medium with elasticity that can return to equilibrium after deformation.

R - universal gas constant - 0.08206 L.atm/mol.K

T - temperature in kelvin - 20 °C + 273 = 293 K

substituting the values in the equation

NaHCO3 + H2SO4 → Na2SO4 + CO2(g) + 2H2O(l)

This shows sodium bicarbonate reacting with sulfuric acid to produce sodium sulfate, carbon dioxide gas, and water.
