The mass of the silver that will raise the water by 1.5 mL is 15.75 g

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

With the above formula, we can obtain the mass of the silver. Details below

Density = mass / volume

Cross multiply

Mass = Density × Volume

Mass of silver = 10.5 × 1.5

The synthesis of the ATP takes place in the organelle known as the mitochondrion. Therefore, option (A) is correct.

Mitochondrion can be described as the membrane-bound organelles in the cytoplasm of all eukaryotic cells, that synthesize adenosine triphosphate (ATP), the main energy source used by the cell.

It is also known as the “Powerhouse of the cell,” Mitochondrion is found inside the cytoplasm and essentially functions as the cell’s digestive system.

Mitochondrion plays a major role in breaking down nutrients and producing energy-rich molecules for the cell. Many of the biochemical reactions in cellular respiration occur within the mitochondria.

The mitochondrion's structure can be described as a double-membraned, rod-shaped structure found in both animal cells and plants.

Answer:

a. x3 and x4 are the first to agree to two significant figures

b. x4 and x5 are the first to agree to three significant figures

Explanation:

8.30 x 10⁻⁵ = x1(0.100)²

8.30 x 10⁻⁵ = 0.01x1

x1 = 8.30 x 10⁻⁵/0.01 = 0.0083

8.30 x 10⁻⁵ = x2(0.100 + 0.0083)²

8.30 x 10⁻⁵ = (0.01172889)x2

x2 = 8.30 x 10⁻⁵/0.01172889

x2 = 0.007076543475128

8.30 x 10⁻⁵= x3 (0.100 + 0.007076543475128)²

8.30 x 10⁻⁵ = 0.011465386162581)x3

x3 = 8.30 x 10⁻⁵/0.011465386162581

x3 = 0.007239180505832

8.30 x 10⁻⁵ = x4 (0.100 + 0.007239180505832)²

8.30 x 10⁻⁵ = (0.011500241835562) x4

x4 = 8.30 x 10⁻⁵/0.011500241835562

x4 = 0.007217239531723

8.30 x 10⁻⁵ = x5 (0.1 + 0.007217239531723)²

8.30 x 10⁻⁵ = (0.011495536452803) x5

Answer:

Explanation:

The protein comprises of two 60-kD polypeptides and two 40-kD polypeptides. Each one of the 40-kD chains has a disulfide-bond, which is directly bonded to a 60-kD chain.

The 100-kD units attach noncovalently to produce a protein with a molecular mass of 200 kD.

The protein consists of 200 kD in size, and the Gel filtration doesn't affect the relationship and interaction among the various subunits in the protein.

When SDS-PAGE takes place, samples are being subjected to boiling of samples and therefore undergoing denaturation conditions. The result causes disorganization in the 100 kD units.

It implies that BME is responsible for the reduction between the R1-S-S-R2 bond between 40 kD and 60 kD to R1-SH and R2-SH, resulting in separate proteins.

However, the reducing agent (BME) main task is reducing disulfide bonds in a protein.

The rate constant that we have at 381 K will be 2.19 M/s.

The Arrhenius equation suggests that the rate of a reaction increases with temperature, because higher temperatures provide more kinetic energy to the reactant molecules, making them more likely to react.

By the use of the Arrhenius equation, we have that;

ln k2/k1 = -Ea/R(1/T2 - 1/T1)

ln k2/0.178 = -37.8 * 10^3/8.314 (1/381 - 1/280)

a) To calculate the minimum frequency of electromagnetic radiation required to release electrons from the metal, you can use the following formula:

f = W / h

where f is the minimum frequency of electromagnetic radiation required, W is the work function of the metal in joules, and h is the Planck constant in joules per second.

Plugging in the values for W and h, you get:

f = (5.86 x 10^-19 J) / (6.626 x 10^-34 J/s) = 8.9 x 10^14 Hz

This is the minimum frequency of electromagnetic radiation required to release electrons from the magnesium metal.

b) To calculate the kinetic energy of the ejected electronic light of frequency 2.00 x 10^14 Hz, you can use the following formula:

KE = hf - W

where KE is the kinetic energy of the ejected electron, h is the Planck constant in joules per second, f is the frequency of the electromagnetic radiation in hertz, and W is the work function of the metal in joules.

Plugging in the values for h, f, and W, you get:

KE = (6.626 x 10^-34 J/s) * (2.00 x 10^14 Hz) - (5.86 x 10^-19 J) = 1.32 x 10^-19 J - 5.86 x 10^-19 J = -4.54 x 10^-20 J

This is the kinetic energy of the ejected electron when light of frequency 2.00 x 10^14 Hz is used to irradiate the magnesium metal. Since the kinetic energy is negative, this means that the electron is not released from the metal when irradiated with this frequency. The frequency of the electromagnetic radiation needs to be higher than the minimum frequency required to release the electron in order for the electron to be ejected from the metal.

The volume of water needed to make the solution is 473.76 mL

We'll begin by calculating the volume of the diluted solution.

M₁V₁ = M₂V₂

15.5 × 5.41 = 0.175 × V₂

83.855 = 0.175 × V₂

Divide both side by 0.175

V₂ = 83.855 / 0.175

V₂ = 479.17 mL

Finally, we shall determine the volume of water needed.

Volume of water = V₂ – V₁

Volume of water = 479.17 – 5.41

Volume of water = 473.76 mL

We can see that an atom with 14 protons, 14 neutrons, and 16 electrons is unstable, and has a -2 charge.

So the correct option is the third one.

An atom with 14 protons, 14 neutrons, and 16 electrons is not stable. The number of protons in an atom, also known as its atomic number, determines its element and its chemical properties. In this case, the atom has 14 protons, which corresponds to the element silicon (Si) on the periodic table.

For an atom to be stable, it should have a balanced number of protons and electrons. Electrons are negatively charged particles that orbit the nucleus of an atom in energy levels or electron shells. The number of electrons in a stable atom should be equal to the number of protons, resulting in a neutral charge overall.

In this case, the atom has 14 protons and 16 electrons, which means it has two more electrons than protons, resulting in a net charge of -2. This is an example of an ion.
