Explanation:

An amino acid is transported by tRNA to the polypeptide chain that is being put together during translation.

The process through which a cell transforms the genetic information contained in an mRNA molecule into a protein is known as translation.

The process of attaching an amino acid to its corresponding transfer RNA is known as amino acid activation, also known as aminoacylation or tRNA charging (tRNA).

The first tRNA's (Met) amino acid will be transferred to the second tRNA's amino acid through the establishment of a peptide bond (in this case, Trp). The tRNA will have this two-amino acid chain attached to it in the A site. After that, the ribosome will advance the mRNA template by one codon.

In the ClO3- ion, there are three bonding pairs of electrons (between chlorine and oxygen) and one lone pair of electrons on the central chlorine atom. This gives us a total of four electron pairs around the central atom.

The ClO3- ion, also known as chlorate ion, consists of one central chlorine atom bonded to three oxygen atoms. To determine the number of lone pairs around the central atom, we need to first find the total number of valence electrons in the ion.
Chlorine has seven valence electrons, while each oxygen atom has six. Therefore, the total number of valence electrons in the ClO3- ion is:
7 + (3 x 6) + 1 = 26
To determine the geometry of the ion, we can use the VSEPR theory. The VSEPR theory states that electron pairs repel each other, and this determines the shape of the molecule/ion.
According to the VSEPR theory, when there are four electron pairs around the central atom, the geometry is tetrahedral. However, since one of the electron pairs is a lone pair, the geometry is distorted. The bond angle between the three bonding pairs of electrons is approximately 109.5 degrees, but the angle between the lone pair and the bonding pairs is slightly less, at around 107 degrees. Therefore, the geometry of the ClO3- ion is distorted tetrahedral.

In the given question, it is stated that we have to find out what hydrogen ions that dissociate were completely neutralized by the hydroxide we added from the base and how many moles of H were neutralized.

Let's first take a look at the chemical reaction involved in this process:

HA + OH → H2O + A-

The hydrogen ions (H+) disassociate from the acid (HA), and the hydroxide ions (OH-) disassociate from the base (B).

We know that one mole of an acid reacts with one mole of a base to form one mole of water. Therefore, to find the number of moles of H that we neutralized, we need to determine the number of moles of OH that we added.

To determine the number of moles of OH that we added, we need to know the volume and molarity of the base solution that we used. Then we can use the formula:

Molarity = moles of solute / volume of solution in liters

Now, let's consider an example:

Suppose we added 0.25 liters of 0.5 M NaOH solution to neutralize 0.5 moles of HCl. We can find the number of moles of OH that we added as follows:

Molarity = moles of solute / volume of solution in liters

0.5 M = moles of NaOH / 0.25 L

moles of NaOH = 0.5 M x 0.25 L

= 0.125 mol

Hence, 0.125 moles of hydrogen ions were neutralized by the hydroxide we added from the base.

The given chemical equation can be balanced as: CH4 + 2O2 → CO2 + 2H2OTherefore, the balanced chemical equation for the reaction between 46 g of CH4 and 32 g of O2 is:CH4 + 2O2 → CO2 + 2H2OMoles of CH4 = (46 g)/(16.04 g/mol) = 2.87 molMoles of O2 = (32 g)/(32 g/mol) = 1 mol.

Moles of CH4 = (46 g)/(16.04 g/mol) = 2.87 molMoles of O2 = (32 g)/(32 g/mol) = 1 molFor the given reaction, one mole of CH4 reacts with 2 moles of O2. Therefore, 2.87 moles of CH4 would react with 2 × 2.87 = 5.74 moles of O2. As we can see from the given values, only 1 mole of O2 is present. Hence, O2 is the limiting reactant.The balanced chemical equation for the reaction between 46 g of CH4 and 32 g of O2 is:CH4 + 2O2 → CO2 + 2H2OOn

The basis of the balanced chemical equation, 2 moles of O2 is required for one mole of CH4. Here, the moles of O2 is lesser than 2 times the moles of CH4, which means O2 is the limiting reactant and CH4 is the excess reactant. Hence, 32 g of O2 will react completely with 1 mole of CH4, and 14.14 g of CO2 and 4 g of H2O will be produced as per the stoichiometry.

Explanation:

The density of ammonia gas (NH3) at 66°C and 2.3 atm pressure is approximately 2.39 g/L.

To find the density of ammonia gas (NH3) at 66°C and 2.3 atm pressure, we can use the ideal gas law:

PV = nRT

where: P is the pressure (2.3 atm),

V is the volume,

n is the number of moles,

R is the ideal gas constant (0.0821 L·atm/mol·K),

T is the temperature (66°C = 339.15 K).

We can rearrange the equation to solve for the volume:

V = (nRT) / P

To find the density, we need to convert the number of moles to grams and divide by the volume:

Density = (n × molar mass) / V

The molar mass of ammonia (NH3) is:

1 atom of nitrogen (N) = 14.01 g/mol

3 atoms of hydrogen (H) = 3 × 1.01 g/mol

Molar mass of NH3 = 14.01 g/mol + 3 × 1.01 g/mol = 17.03 g/mol

Substituting the values into the equations:

V = (nRT) / P = (1 mol × 0.0821 L·atm/mol·K × 339.15 K) / 2.3 atm ≈ 12.06 L

Density = (n × molar mass) / V = (1 mol × 17.03 g/mol) / 12.06 L ≈ 2.39 g/L

Therefore, the density of ammonia gas (NH3) at 66°C and 2.3 atm pressure is approximately 2.39 g/L.

Explanation:

The reaction between solid calcium carbonate and a mineral acid such as aqueous HCl is a neutralization reaction and occurs with the evolution of CO2 gas.

The balanced equation is given below

CaCO3 + 2HCl ---> CaCl2 + H20 + CO2

The product CaCl2 is water soluble which accounts for why the stain is removed, while CO2 gas escapes away from the reaction surface.

Answer:

CaCO3(s) + 2HCl(aq) -------> CaCl2(aq) + 2CO2(g) + H2O(l)

Explanation:

CaCO3(s) + 2HCl(aq) -------> CaCl2(aq) + 2CO2(g) + H2O(l)

When an acid reacts with a metal carbonate a salt, carbon dioxide and water are formed. Hard water usually contain Ca^2+ in the form of Ca(HCO3)2. Minor heating causes CaCO3(calcium carbonate) to deposit on surfaces through which the hard water passes.

Calcium carbonate reacts with acids to produce a calcium salt, water and carbon dioxide: Calcium carbonate + Hydrochloric acid → Calcium chloride + Water + Carbon dioxide. The carbonate radical breaks up into carbon dioxide and oxygen; the oxygen binds with the acid's hydrogen ions to make water; and a solution of calcium chloride remains.

Pb3O4

Explanation:

According to this question, 3.425g of lead oxide was reduced to form 3.105g of lead in an experiment. Since lead oxide contains both lead (Pb) and oxygen (O) element,

Mass of lead oxide = 3.425g

Mass of lead = 3.105g

Mass of oxygen = (3.425g - 3.105g) = 0.320g

Next, we convert each mass value to mole by dividing by respective molar mass

Pb = 3.105g ÷ 207.2 = 0.0149mol

O = 0.320g ÷ 16 = 0.02mol

Next, we divide each mole value by the smallest (0.0149)

Pb = 0.0149mol ÷ 0.0149mol = 1

O = 0.02mol ÷ 0.0149mol = 1.342

Multiply each ratio value by 3 to get:

Pb = 1 × 3 = 3

O = 1.342 × 3 = 4.026

The whole number ratio, approximately, of Pb and O is 3:4, hence, their empirical formula is Pb3O4.

The Miller-Urey experiment provides evidence that the nucleotide base adenine can be created by combining hydrogen cyanide and ammonia in water. Many further experiments were sparked by this one.

His work resulted in a significant amount of adenine, whose molecules were created from 5 molecules of HCN. Additionally, under these circumstances, a large number of ammonia atoms is produced from HCN and ammonia.

When delta G value for a particular reaction is negative, then we can say that : there are fewer reactant molecules and then product molecules.

A negative ∆G means that reactants have more free energy than the products. Exergonic reactions are also called spontaneous reactions, as they can occur without addition of energy.

When used in a reaction, delta G is the difference in free energy between  products and reactants. If this value is negative, then the reaction is spontaneous and if it is positive, then the reaction is non-spontaneous. If it is zero, then the reaction is at equilibrium.

Answer:

The molar mass of the gas is closest to that of molecular bromine (Br2), which has a molar mass of 159.8 g/mol. Therefore, the diatomic gas is likely to be bromine.

Explanation:

To solve this problem, we can use the ideal gas law, which relates the pressure, volume, temperature, and number of moles of a gas. The ideal gas law is given by:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

First, we need to convert the temperature and volume to Kelvin and liters, respectively:

T = 23.0°C + 273.15 = 296.15 K

V = 125.0 mL / 1000 mL/L = 0.125 L

Next, we can rearrange the ideal gas law to solve for the number of moles:

n = PV/RT

where R is the ideal gas constant, which has a value of 0.08206 L·atm/(mol·K).

We can substitute the given values into this equation:

n = (750. torr)(0.125 L) / (0.08206 L·atm/(mol·K))(296.15 K) = 0.00408 mol

Now we can calculate the molar mass of the gas by dividing its mass by its number of moles:

molar mass = mass / moles

molar mass = 0.360 g / 0.00408 mol = 88.2 g/mol

The molar mass of the gas is 88.2 g/mol.

To determine the identity of the gas, we can compare its molar mass to the molar masses of common diatomic gases. The molar mass of the gas is closest to that of molecular bromine (Br2), which has a molar mass of 159.8 g/mol. Therefore, the diatomic gas is likely to be bromine.

The molar mass of the diatomic gas is approximately 67.9 g/mol. Considering common diatomic gases, it is likely to be Cl₂ (chlorine gas), which has a molar mass of 70.9 g/mol.

To determine the molar mass of the diatomic gas, we can use the Ideal Gas Law equation:

PV = nRT

First, we need to convert the given information to appropriate units.

1. Volume (V): 125.0 mL = 0.125 L (1 L = 1000 mL)

2. Temperature (T): 23.0 °C = 296.15 K (K = °C + 273.15)

3. Pressure (P): 750 torr = 0.9869 atm (1 atm = 760 torr)

Now we can rearrange the Ideal Gas Law equation to solve for n (moles of gas):

n = PV / RT

Plugging in the given values:

n = (0.9869 atm)(0.125 L) / (0.0821 L atm/mol K)(296.15 K)
n ≈ 0.0053 moles

Now, we can find the molar mass (MM) of the diatomic gas using the given mass and the calculated moles:

MM = mass/moles

MM = 0.360 g / 0.0053 moles
MM ≈ 67.9 g/mol
