The answer is "2 and 4"

Location 2 and 4 are likely to have subatomic particles that are constantly in motion,thus the correct option is D.

In physics, a subatomic particle is a particle smaller than an atom.According to the Standard Model of particle physics, a subatomic particle can be either a composite particle, which is composed of other particles (for example, a proton, neutron, or meson), or an elementary particle, which is not composed of other particles Particle physics and nuclear physics study these particles and how they interact.

Experiments show that light could behave like a stream of particles (called photons) as well as exhibiting wave-like properties. This led to the concept of wave–particle duality to reflect that quantum-scale particles behave like both particles and waves; they are sometimes called wavicles to reflect this.

Thus,  the correct option is D.

Answer:

-70.87 kJ

Explanation:

Let's consider the following balanced equation.

1/2 O₂(g) + SO₂(g) ⇄ SO₃(g)

We can calculate the standard Gibbs free energy of reaction (ΔG°r) from the standard Gibbs free energies of formation (ΔG°f) using the following expression.

ΔG°r = 1 mol × ΔG°f(SO₃(g)) - 1/2 mol × ΔG°f(O₂(g) - 1 mol × ΔG°f(SO₂(g))

ΔG°r = 1 mol × (-371.06 kJ/mol) - 1/2 mol × 0 kJ/mol - 1 mol × (-300.194 kJ/mol)

ΔG°r = -70.87 kJ

Answer: (a) [S] = 0.0016M

              (b) Vmax = 3V; Vmax = [tex]\frac{3V}{2}[/tex]; Vmax = [tex]\frac{11V}{10}[/tex]

              (c) Enzyme A: black graph; Enzyme B = red graph

Explanation: Enzyme is a protein-based molecule that speed up the rate of a reaction. Enzyme Kinetics studies the reaction rates of it.

The relationship between substrate and rate of reaction is determined by the Michaelis-Menten Equation:

[tex]V=\frac{V_{max}[S]}{K_{M}+[S]}[/tex]

in which:

V is initial velocity of reaction

Vmax is maximum rate of reaction when enzyme's active sites are saturated;

[S] is substrate concentration;

Km is measure of affinity between enzyme and its substrate;

(a) To determine concentration:

[tex]0.25V_{max}=\frac{V_{max}[S]}{0.005+[S]}[/tex]

[tex]0.25V_{max}(0.005+[S])=V_{max}[S][/tex]

[tex]0.00125+0.25[S]=[S][/tex]

0.75[S] = 0.00125

[S] = 0.0016M

For a Km of 0.005M, substrate's concentration is 0.0016M.

(b) Still using Michaelis-Menten:

[tex]V=\frac{V_{max}[S]}{K_{M}+[S]}[/tex]

Rearraging for Vmax:

[tex]V_{max}=\frac{V(K_{M}+[S])}{[S]}[/tex]

(b-I) for [S] = 1/2Km

[tex]V_{max}=\frac{V(K_{M}+0.5K_{M})}{0.5K_{M}}[/tex]

[tex]V_{max}=\frac{V(1.5K_{M})}{0.5K_{M}}[/tex]

[tex]V_{max}=[/tex] 3V

(b-II) for [S] = 2Km

[tex]V_{max}=\frac{V(K_{M}+2K_{M})}{2K_{M}}[/tex]

[tex]V_{max}=\frac{V(3K_M)}{2K_M}[/tex]

[tex]V_{max}=\frac{3V}{2}[/tex]

(b-III) for [S] = 10Km

[tex]V_{max}=\frac{V(K_{M}+10K_M)}{10K_M}[/tex]

[tex]V_{max}=\frac{V(11K_{M})}{10K_{M}}[/tex]

[tex]V_{max}=\frac{11V}{10}[/tex]

(c) Being the affinity between enzyme and substrate, the lower Km is the less substrate is needed to reach half of maximum velocity.

Km of enzyme A is 2μM and of enzyme B is 0.5μM.

Enzyme B has lower Km than enzyme A, which means the first will need a lower concnetration of substrate to reach half of Vmax.

Analyzing each plot, notice that the red-coloured graph reaches half at a lower concentration, therefore, red-coloured plot is for enzyme B, while black-coloured plot is for enzyme A

Answer:

Kinetic theory of gases is a description of gas as a large number of non-stop random moving particles (atoms or molecules, generally without distinction in physics, are called molecules). Fast-moving molecules continuously collide with other molecules or the walls of the container. Molecular motion theory is to explain the macroscopic properties of gas, such as pressure, temperature, volume, etc., through the composition and motion of molecules. The theory of molecular motion believes that pressure does not come from static repulsion between molecules, as Newton’s conjecture, but from collisions between molecules that move thermally at different speeds.

The molecule is too small to be seen directly. The random movement of pollen particles or dust particles under the microscope-Brownian motion, is a direct result of molecular collisions. This can be used as evidence of the existence of the molecule.

Temperature is a measure of the average kinetic energy of the particles in a substance. Temperature of a volume of air represents the average kinetic energy of its molecules. Temperature is a measure of the average kinetic energy of a substance.

According to Kinetic Molecular Theory, the average kinetic energy of gas molecules is a function only of temperature. where T is the Kelvin temperature and k is Boltzmann's constant.

The specific heat capacity of the granite is 0.796 J/gºC

We'll begin by calculating the heat absorbed by the water. This can be obtained as follow:

Mass of water (M) = 400 g

Initial temperature of water (T₁) = 20 °C

Final temperature (T₂) = 28.5 °C

Change in temperature (ΔT) = T₂ – T₁ = 28.5 – 20 = 8.5 °C

Specific heat capacity of water (C) = 4.184 J/gºC

Q = MCΔT

Q = 400 × 4.184 × 8.5

Thus, the heat absorbed by the water is 14225.6 J

Heat absorbed = Heat released

Heat absorbed = 14225.6 J

Mass of granite (M) = 250 g

Initial temperature of granite (T₁) = 100 °C

Final temperature (T₂) = 28.5 °C

Change in temperature (ΔT) = T₂ – T₁ = 28.5 – 100 = –71.5 °C

Q = MCΔT

–14225.6 = 250 × C × –71.5

–14225.6 = –17875 × C

Divide both side by –17875

C = –14225.6 / –17875

Therefore, the specific heat capacity of the granite is 0.796 J/gºC

Answer:

Theoretical yield of CaCO₃ is 2.002 g.

Explanation:

Given data:

Mass of K₂CO₃ = 2.5 g

Mass of CaCl₂ = 2 g

Theoretical yield of CaCO₃ = ?

Solution:

Chemical equation:

K₂CO₃ +  CaCl₂      →     CaCO₃ + 2KCl

Number of moles of K₂CO₃:

Number of moles = mass/molar mass

Number of moles = 2.5 g/ 138.205 g/mol

Number of moles = 0.02 mol

Number of moles of CaCl₂:

Number of moles = mass/molar mass

Number of moles = 2 g/ 110.98 g/mol

Number of moles = 0.02 mol

Now we will compare the moles of CaCO₃ with K₂CO₃ and CaCl₂.

                CaCl₂             :              CaCO₃

                    1                  :                  1

                  0.02              :              0.02

                 K₂CO₃            :               CaCO₃

                   0.02             :               0.02

Theoretical yield of CaCO₃:

Mass = number of moles × molar mass

Mass = 0.02 mol × 100.1 g/mol

Mass =  2.002 g

Theoretical yield of CaCO₃ is 2.002 g.

Answer:

See attached picture.

Explanation:

Hello.

As you can see on the attached picture, this Lewis structure requires all the elements to attain eight electrons after bonding, that is why the phosphorous is bonded with the two carbon atoms via a single bond with the carbon having the three fluorine atoms and a double bond with the carbon having the two carbon atoms.

Such arrangement is due to the fact that:

- P gets eight electrons by obtaining three from the two sided carbon atoms.

- The first carbon gets eight electrons from its initial four, three provided by each surrounding fluorine and one from the central phosphorous.

- Each fluorine gets eight valence electrons from their initial seven and one from the available carbon atoms.

Answer:

Corresponding with orange light, is the wavelength that blue solutions absorb the most.

Explanation:

When light is passed through a solution of a particular color, light of other wavelength or color, is absorbed and disappears, whereas the wavelength of light corresponding to the color of that solution is transmitted. The color of light absorbed the most is that which is complementary (opposite it in the color wheel) to the light which is transmitted. In a color wheel, blue is complementary to orange color, red is complementary to green and yellow is complementary to violet.

Therefore, in a blue substance (as in the blue solutions), there would be a strong absorbance of the complementary color of light, orange. Since the wavelength of orange color of light is between 600 - 640 nm, with maximum absorbance of orange light occurring around 633 nm, the wavelength of 633 nm is used to analyze the standard solutions and drink samples.

Answer:

Thermoplastics have low melting temperature because of the week van der Waals bonds between their Long Chain Molecules

Polymer chains once synthesized they will remain stable in the environment because of the strong covalent bonds in the Long Chain Molecules

Explanation:

Thermoplastics are polymers that are easily melted and changed to another shape as many times as possible. They become molten when they are heated and solidify when cooled. Examples of thermoplastics include; polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamides, polyesters, and polyurethanes.

Polymers are organic materials that consists of a long chain of atoms held together by strong covalent bonds. Polymers constitute an important environmental concern because most polymers are non biodegradable and remain in the environment almost indefinitely.

An electron moved from a lower energy level to a higher energy level, and during the transition, a random amount of light was released. Option A

An electron is a kind of subatomic particle that has a negative charge. It is possible for it to be free (meaning that it is not associated with the nucleus of any atom) or it may be tied to the nucleus of an atom.

Electrons are sub-atomic particles that may be found in each atom of any chemical element and can occupy different energy levels. These electrons are capable of transitioning between different energy levels.

Electrons may transition from a state with a lower energy level, also known as the ground state, to a state with a higher energy level, also known as an excited state. Alternatively, electrons can transition from a state with a higher energy level to a state with a lower energy level.

When an electron goes from a lower energy level to a higher energy level, the atom takes in more energy, but when the electron moves from a higher energy level to a lower energy level, the additional energy is expelled mostly in the form of light.

Answer:

110.91 g of CaCl2

Explanation:

11.9 grams of CaCl₂ is required to make 1 Liter of 0.1M solution.

We first need to calculate the molecular weight of calcium chloride CaCl₂.

The atomic weight of Ca = 40.01

and the atomic weight of Cl₂ = 2×35.45 = 70.90

So, the molecular weight of CaCl₂ = 40.01 + 70.90 = 110.91

This means that 110.91 g of CaCl₂ mixed with enough water will produce 1Liter of 1M solution.

Now, to calculate the amount of CaCl₂ required to make 1 Liter of 0.1M solution we use:

grams of chemical = (molarity of solution in mole/liter) x (MW of chemical in g/mole) x (ml of solution) ÷ 1000 ml/liter

= 0.1 × 110.91 × 1000 ÷ 1000

= 11.09 grams

So, 11.09 grams of CaCl₂ will be used.
