Answer:

Y: tRNA

Z: DNA

Explanation:

This question involves two different nucleic acid molecules that are involved in protein production. Xavier used a chart to highlight the functions these nucleic acids perform during protein synthesis.

- Transfer RNA known as tRNA is a type of RNA molecule found in the ribosomes. It functions to read the mRNA codon and carry corresponding amino acid to the ribosomes for linking with one another. Based on this, "Y" on the chart is a tRNA molecule.

- Deoxyribonucleic acid, also known as DNA, is a molecule found in the NUCLEUS whose function is to store the genetic information in the cell. DNA carries the information needed for the synthesis of protein. Based on this, Z is a DNA molecule.

Answer:

12 moles of F₂

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

N₂ + 3F₂ —> 2NF₃

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Finally, we shall determine the number of mole of F₂ needed to produce 8 moles of NF₃. This can be obtained as illustrated below:

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of NF₃.

Therefore, Xmol of F₂ will react to produce 8 moles of NF₃ i.e

Xmol of F₂ = (3 × 8)/2

Xmol of F₂ = 12 moles

Thus, 12 moles of F₂ is needed for the reaction.

[tex]\% rec=80.4\%[/tex]

Explanation:

Hello!

In this case, since the percent recovery for this crystallization operation is computed as shown below:

[tex]\% rec=\frac{m_{recovered}}{m_{initial}} *100\%[/tex]

Thus, by plugging in the initial 8.95 g and the recovered 7.20 g, we obtain:

[tex]\% rec=\frac{7.20g}{8.95g} *100\%\\\\\% rec=80.4\%[/tex]

The answer to your question is given below

Explanation:

From the question given above, the following data were obtained:

Mass of cholesterol (in μg) = 203 μg

Mass of cholesterol (in Kg) =?

The following conversion scale can be used to convert micro grams (μg) to kilogram (kg).

1 μg = 1×10¯⁹ Kg

Therefore,

203 μg = 203 μg × 1×10¯⁹ Kg / 1 μg

203 μg = 2.03×10¯⁷ Kg

Thus, 203 μg is equivalent to 2.03×10¯⁷ Kg

Answer:

Ba(NO₃)₂(aq) + Na₂SO₄(aq) ⇒ BaSO₄(s) + 2 NaNO₃(aq)

Explanation:

Let's consider the unbalanced double displacement equation for the reaction of an aqueous solution of barium nitrate and an aqueous solution of sodium sulfate.

Ba(NO₃)₂(aq) + Na₂SO₄(aq) ⇒ BaSO₄(s) + NaNO₃(aq)

To get the balanced equation, we will multiply NaNO₃(aq) by 2.

Ba(NO₃)₂(aq) + Na₂SO₄(aq) ⇒ BaSO₄(s) + 2 NaNO₃(aq)

Explanation:

...Dissolves 15.0g of styrene (C₈H₈) in 250.mL of a solvent with a density of 0.88g/mL...

Molarity is defined as moles of solute (Styrene in this case) per liter of solution whereas molality is the moles of solute per kg of solvent. Thus, we need to find the moles of styrene, the volume in liters of the solution and the mass in kg of the solvent as follows:

Moles styrene:

Molar mass C₈H₈:

8C = 12.01g/mol*8 = 96.08g/mol

8H = 1.005g/mol* 8 = 8.04g/mol

96.08g/mol + 8.04g/mol = 104.12g/mol

Moles of 15.0g of styrene are:

15.0g * (1mol / 104.12g) = 0.144 moles of styrene

Liters solution:

250mL * (1L / 1000mL) = 0.250L

kg solvent:

250mL * (0.88g/mL) * (1kg / 1000g) = 0.220kg

Molarity is:

0.144 moles / 0.250L =

Molality is:

0.144 moles / 0.220kg =

Answer: 0.00507 moles

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]

where,

n = moles of solute

[tex]V_s[/tex] = volume of solution in ml

1. moles of napthalene = [tex]\frac{3.09\times 0.001\times 100.0}{100}=0.000309moles[/tex]

2. moles of methyl napthalene = [tex]\frac{10.0\times 0.001\times 100.0}{1000}=0.001mole[/tex]

3. moles of dimethyl napthalene = [tex]\frac{23.2\times 0.001\times 100.0}{1000}=0.00232moles[/tex]

4. moles of trimethyl napthalene = [tex]\frac{14.4\times 0.001\times 100.0}{1000}=0.00144moles[/tex]

Thus total moles of all naphthalene compounds combined is (0.000309+0.001+0.00232+0.00144) = 0.00507.

Answer:

44x+7y

Explanation:

The number of molecules in one mole of water is 6.02 × 10²³. Therefore, the number of moles of carbon dioxide which contains 9.04 × 10²³ molecules is 1.50.

The number of atoms that constitutes one mole of a substance is called Avogadro number. It is equal to  6.02 × 10²³. Thus, one mole of every elements contains Avogadro number of atoms.

Similarly, one mole of a compound contains  6.02 × 10²³ number of molecules. Thus, one mole of carbon dioxide contains these much molecules.

Given the number of molecules of water = 9.04 × 10²³

Then, no.of moles = number of molecules/ Avogadro number.

no.of moles =9.04× 10²³ /6.022 × 10²³  = 0.68.

Therefore, the number of moles of H₂O that contains 9.04 × 10²³molecules is 1.50

Answer:

1. nitric acid: sa

2. perchloric acid: sa

3. hydrofluoric acid: wa

Explanation:

A strong acid (sa) is the one that is completely dissociated into ions in water. Conversely, a weak acid (wa) is not completely dissociated in water.

From the options, the strong acids are:

1. nitric acid (HNO₃). It dissociates completely into ions when is dissolved in water, as follows:

HNO₃ → H⁺ + NO₃⁻

2. perchloric acid (HClO₄). It is completely dissociated in water as follows:

HClO₄ → H⁺ + ClO₄⁻

The weak acid is hydrofluoric acid (HF). In water, only a small proportion is dissociated into ions. The proportion of ions formed is given by the equilibrium constant Ka. The dissociation is written by using double arrows:

HF ⇄ H⁺ + F⁻

Answer:

water - irrigation

forests - paper

wetlands - trapping sediments

parks - preserving aesthetic value

Explanation:

One important use of water is for the irrigation of farmlands. Irrigation makes it possible for farming activities to continue all year round.

The papers yield pulp which is used to produce paper. This implies that paper is important product obtained from the forest.

The wetlands trap sediments and retain particulates from both onsite and offsite sources(blue earth county).

A park serves to preserve aesthetic value. This is a primary importance of the parks.

Answer:

40.5%  is abundance of X-122

Explanation:

we know there are two naturally occurring isotopes of X, X-120  and X-122.

First of all we will set the fraction for both isotopes

X for the isotopes having mass 122

1-x for isotopes having mass 12 0

The average atomic mass of X is 120.81 amu

we will use the following equation,

122x + 120 (1-x) = 120.81

122x + 120 - 120x = 120.81

122x- 120x = 120.81 -120

2x = 0.81

x= 0.81/2

x= 0.405

0.405 × 100 = 40.5%

40.5%  is abundance of X-122 because we solve the fraction x.

now we will calculate the abundance of X-120.

(1-x)

1 - 0.405 = 0.595

0.595  × 100 = 59.5 %

59.5 %  for X-120.

The ground water reservoir is found underground in cracks and spaces in the soil, sand and rock.

Ground water is a very important portion of the water cycle where water is stored in an aquifer.

Aquifers are porous and permeable formations that stores ground water within them.

In this manner, ground water system is recharged by infiltration of water from the surface. Water percolates and collects inside an aquifer in this manner.
