Explanation:

Answer:

15 moles of hydrogen gas are needed to react with 15 moles of chlorine gas.

Explanation:

The balanced reaction is:

H₂ (g) + Cl₂ (g) → 2 HCl (g)

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of the compounds participate in the reaction:

Then you can apply the following rule of three:  If 1 mole of Cl₂ reacts with 1 mole of H₂, 15 moles of Cl₂ with how many moles of H₂ does it react?

\(moles of H_{2} =\frac{15 moles of Cl_{2} *1mole of H_{2}}{1moles of Cl_{2}}\)

moles of H₂= 15

15 moles of hydrogen gas are needed to react with 15 moles of chlorine gas.

The binding of the amino acid in aminoacyl-tRNA involves the formation of an ester bond.  Option b

Aminoacyl-tRNA is a complex molecule that plays a crucial role in protein synthesis. It consists of a tRNA molecule covalently linked to an amino acid. The amino acid is attached to the 3' end of the tRNA molecule through an ester bond.

An ester bond is formed between the carboxyl group (-COOH) of the amino acid and the hydroxyl group (-OH) of the ribose sugar at the 3' end of the tRNA molecule. This ester bond is also referred to as an ester linkage. The formation of the ester bond is catalyzed by the enzyme aminoacyl-tRNA synthetase.

The ester bond in aminoacyl-tRNA is essential for protein synthesis. During translation, the aminoacyl-tRNA molecule carries the specific amino acid to the ribosome, where it is incorporated into the growing polypeptide chain. The ester bond is later hydrolyzed, releasing the amino acid for further use in protein synthesis.

In summary, the binding of the amino acid in aminoacyl-tRNA involves the formation of an ester bond between the carboxyl group of the amino acid and the hydroxyl group of the ribose sugar in the tRNA molecule.

In a primitive cubic arrangement, each unit cell contains one composite atom.

Here's a step-by-step explanation:

1. In a primitive cubic arrangement, there is one atom at each corner of the unit cell.
2. Each corner atom is shared by 8 adjacent unit cells.
3. Therefore, the contribution of each corner atom to a single unit cell is 1/8 (since it is shared by 8 cells).
4. Since there are 8 corner atoms in total, their combined contribution to a single unit cell is 8 * (1/8) = 1 composite atom.

So, there is 1 composite atom contained in a unit cell of a primitive cubic arrangement.

Cosmic background radiation is Leftover radiation from the big bang.

What is Cosmic radiation?
When primary photons and particles from outside of the solar system interact with elements of the earth's atmosphere, cosmic radiation, an ionising radiation, is created. The sun's discharge of charged particles, also known as solar flares or "sun storms," is a secondary source of cosmic radiation. The environment in which we live naturally contains ionising radiation, which can be found in the soil, structures, food we eat, and even the bones in our bodies.

Nonionizing radiation, which also includes UV light, radio waves, as well as microwaves, is the other type. Natural radiation has been present in the environment where humans, animals, as well as plants have all evolved, and, with very few exceptions, it poses little danger to human health.

The measure of the amount of the solute dissolved in the given amount of the solvent or solution is said to be the concentration of the solution.

It is given by the expression,

Concentration of the solution = mass of the solute/total volume of the solution

Units: g/mL

The concentration of the solution in units of molarity is given by the expression,

Molarity = (no. of moles of the solute)/(Volume in L)

Units: moles/L

It is given that the solute is barium hydroxide - Ba(OH)₂

The mass of Ba(OH)₂ = 2.81 g

When in dissolved in water, the total volume of the solution = 25.6 mL

The molar mass of Ba(OH)₂ = 171.34 g/mol

Then,

No. of moles = (mass of Ba(OH)₂)/(molar mass of Ba(OH)₂)

i.e.,

No. of moles = \(\frac{2.81}{171.34}\) = 0.0164 mole

Concentration = mass of the solute/total volume

I.e., C = \(\frac{2.81}{25.6}\) = 0.10976 g/mL

Then the concentration of the solution in units of molarity is,

Molarity = (no. of moles)/(Volume of the solution in L)

⇒ Molarity = \(\frac{0.0164}{25.6/1000}\) = 0.64 M

Answer:

The correct answer is 10 core electrons and one valence electron.

Explanation:

The electrons in an atom, which are not valence and do not take part in chemical bonding are known as core electrons. The core electrons and the nucleus of an atom produces the atomic core. These core electrons are held tightly with the nucleus. On the other hand, the outer shell electrons, which are associated with an atom and take part in the generation of a chemical bond is the outer shell is open are known as valence electrons.

In the given question, the atomic number of an element is 11, thus, the electronic configuration will be,

Hence, there is only one valence electron and 10 core electrons.

This problem is providing the energy of a photon of light as 2.95 × 10⁻¹⁷ J and it is required to calculate its frequency, according to the electromagnetic spectrum theory. At the end, the answer turns out to be 4.52x10¹⁶ Hz according to the following:

In chemistry, we use the electromagnetic spectrum in order to know how the wavelength, frequency and energy of particles are related to each other. In this particular case, we have a photon and the frequency can be calculated with the following arrangement:

\(E=h\nu\\\\\nu=\frac{E}{h}\)

Whereas E is the energy, h the Planck's constant and ν the frequency. Thus, we plug in these first two to obtain:

\(\nu=\frac{2.95x10^{-17}J}{6.626x10^{-34}J*s}\\\\\nu=4.45x10^{16}s^{-1}=4.45x10^{16}Hz\)

The final temperature is 280.59 degrees Celsius.

The term atmospheres (atm), defined as follows: A mercury column one millimetre high would impose a pressure of one atm, or 1.01325 x 105 Pa. millimetres of mercury (mmHg). One atmosphere of pressure is generated by a mercury column that is 760 mm high. Because pressure and force are connected, you may use the physics equation to compute one if you know the other.

P1V1/T1 = P2V2/T2

Where P1, V1, and T1 are the initial pressure, volume, and temperature, and P2, V2, and T2 are the final pressure, volume, and temperature.

Given:

Initial pressure (P1) = 1.015 atm

Initial volume (V1) = 9.00 L

Initial temperature (T1) = -211.76 °C (62.39 K)

Mass of hydrogen gas initially (m1) = 2.035 g

Additional mass of hydrogen gas added (m2) = 2.099 g

Final pressure (P2) = 20.15 atm

PV = nRT

n1 = m1/MH2 = 2.035 g / 2.016 g/mol = 1.011 mol

n2 = m1/MH2 + m2/MH2 = 2.035 g / 2.016 g/mol + 2.099 g / 2.016 g/mol = 2.059 mol

We can assume that the volume of the container is constant, so we can set V1 = V2 in the combined gas law equation:

P1/T1 = P2/T2

Solving for T2:

T2 = P2T1V1 / (P1*V2)

Substituting the values:

V2 = V1 = 9.00 L

T2 = (20.15 atm)(62.39 K)(9.00 L) / (1.015 atm)(2.059 mol)(8.314 J/(mol*K))

T2 = 553.75 K or 280.59 °C

The probability of occupying the second energy level in an energy diagram of two energy levels, one at 0 cm-1 and one at 300 cm-1, will be 0.15 when the temperature is 874 K (600°C)

We can write the formula as, Substituting the values: E2 - E1 = 300 cm-1 (which equals to 3 × 104 m-1 or 3.96 × 10-19 J).Then the probability of occupying the second level be 0.15 when the temperature is 874 K (600°C).

If two particles are in the second energy level, then the temperature will be higher than in case a. This is because having two particles in the second energy level (instead of none) indicates that there is an external source of energy that has raised the temperature of the system, since at lower temperatures, particles will occupy the lowest possible energy level.
