What kinds of organisms have "naked" DNA?

Answers

Naked DNA refers to DNA that is not associated with proteins, lipids, or any other molecule to help protect it.

Answer:

The DNA in prokaryotes is naked DNA.

Explanation:

Prokaryotes have cell walls which are a network of fibres that provides the cell with strength and rigidity. This network in the cell wall allows the cell to be freely permeable. These differ from eukaryotes which have a nucleus containing genetic information (DNA).

Consider the information provided in experiment #3 Figure 2. Three different variables are compared for C3H8 (propane) and H2O (water). The strength of the intermolecular forces are responsible for the behavior of the two compounds.
Identify the intermolecular force for the two compounds.

Which one is stronger?

Explain how the strength of intermolecular forces plays a role in at least two of the properties (volatility, boiling point, or surface tension) for C3H8 (propane) and H2O (water).

Cite evidence from the data to explain your reasoning.


Experiment #3: The student follows study #2 with a comparison of propane (C3H8) and water. Volatility is the tendency for a substance to vaporize and it was found that propane vaporizes quickly while water vaporized slowly. Surface tension is a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid. It is this phenomenon which allows a water strider or lizard to run across the surface of water.

Solubility and melting point are two examples of physical properties.

Answers

Answer: True

Explanation:

Solubility is a physical property. The reason is because it can be determined by simple observation and does not change the chemical composition of the material. If the material is soluble, the solubility is the maximum amount of material that dissolves in a solvent at a given temperature.

A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Answer: True

Explanation: These are both examples of physical properties

Radioactive isotope X has a half-life of 500,000 years. This isotope may be found in some types of volcanic rocks. A particular sample of volcanic rock taken from a layer that covered up some of the earliest known human-like footprints contains 0.125 mg of isotope X. The volcanic rock sample originally contained 8.00 mg of isotope X. How long ago were these footprints made. I need the equation. Thanks. please I am stuck on this question. PLEASE

Answers

Answer:

The age of the earliest known human-like footprints is approximately 3000000 years.

Explanation:

Decay of isotopes is represented by the following ordinary differential equation:

[tex]\frac{dm}{dt} = -\frac{m}{\tau}[/tex] (Eq. 1)

Where:

[tex]\frac{dm}{dt}[/tex] - First derivative of mass with respect to time, measured in miligrams per year.

[tex]m[/tex] - Current mass of the isotope, measured in miligrams.

[tex]\tau[/tex] - Time constant, measured in years.

Now we proceed to obtain the solution of the differential equation:

[tex]\int\limits {\frac{dm}{m} } = -\frac{1}{\tau}\int dt[/tex]

[tex]\ln m = -\frac{t}{\tau}+C[/tex]

[tex]m(t) = e^{-\frac{t}{\tau}+C }[/tex]

[tex]m(t) = m_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (Eq. 2)

Where:

[tex]m_{o}[/tex] - Initial mass of the isotope, measured in miligrams.

[tex]t[/tex] - Time, measured in years.

[tex]\tau[/tex] - Time constant, measured in years.

We proceed to clear time within the formula presented above:

[tex]\ln \frac{m(t)}{m_{o}} = -\frac{t}{\tau}[/tex]

[tex]t = -\tau \cdot \ln \frac{m(t)}{m_{o}}[/tex]

In addition, time constant can be found as a function of half-life:

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (Eq. 3)

If we know that [tex]t_{1/2} = 500000\,yr[/tex], [tex]m_{o} = 8\,mg[/tex] and [tex]m(t) = 0.125\,mg[/tex], the age of the earliest known human-like footprints is:

[tex]\tau = \frac{500000\,yr}{\ln 2}[/tex]

[tex]\tau \approx 721347.520\,yr[/tex]

[tex]t = -(721347.520\,yr)\cdot \ln \left(\frac{0.125\,mg}{8\,mg} \right)[/tex]

[tex]t \approx 3000000\,yr[/tex]

The age of the earliest known human-like footprints is approximately 3000000 years.

C) 0.5912 g C8H18
D) 104 kg CaO
Express all answers to 4 sig figs

Answers

Answer:

A = 1.627 ×10²³ molecules of CF₂Cl₂.

B = 809.4 ×10²³ molecules of Fe(NO₃)₂.

C = 0.03117 ×10²³ molecules of C₈H₁₈.

D= 1116 ×10²³ molecules of CaO.

Explanation:

A)

Given data:

Mass of CF₂Cl₂ = 32.66 g

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles = mass/ molar mass

Number of moles = 32.66 g/ 120.9 g/mol

Number of moles = 0.2701 mol

Number of molecules:

1 mole = 6.022×10²³ molecules

0.2701 mol×6.022×10²³ molecules / 1mol = 1.627 ×10²³ molecules of CF₂Cl₂.

B) Given data:

Mass of Fe(NO₃)₂ = 24.2 Kg  (24.2×1000 = 24200 g)

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles = mass/ molar mass

Number of moles = 24200 g/ 180 g/mol

Number of moles = 134.4 mol

Number of molecules:

1 mole = 6.022×10²³ molecules

134.4 mol×6.022×10²³ molecules / 1mol =809.4 ×10²³ molecules of Fe(NO₃)₂.

C) Given data:

Mass of C₈H₁₈= 0.5912 g

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles = mass/ molar mass

Number of moles = 0.5912 g/ 114.22 g/mol

Number of moles = 0.005176 mol

Number of molecules:

1 mole = 6.022×10²³ molecules

0.005176 mol×6.022×10²³ molecules / 1mol =0.03117 ×10²³ molecules of C₈H₁₈.

D) Given data:

Mass of CaO = 104 Kg  (104×1000 = 104,000 g)

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles = mass/ molar mass

Number of moles = 104,000 g/ 56.1 g/mol

Number of moles = 1854 mol

Number of molecules:

1 mole = 6.022×10²³ molecules

1854 mol×6.022×10²³ molecules / 1mol = 1116 ×10²³ molecules of CaO.

A student dissolved a 0.139g sample of oxalic acid, H2C2O4, in water in an Erlenmeyer flask. Then the student titrated the H2C2O4 solution in the flask with a solution of KMnO4, which has a dark purple color. The balanced chemical equation for the reaction that occurred during the titration is shown above. (a) Identify the species that was reduced in the titration reaction. Justify your answer in terms of oxidation numbers.

Answers

Answer:

MnO4 − was reduced

C2 O4^2- was oxidized

Explanation:

2MnO4 −(aq)  +5H +(aq)  +2 C2 O4^2-(aq)  +6H+(aq)  →2Mn2+(aq) + 10CO2(g)  +8H2 O(l)

A redox reaction is characterized by a change in the oxidation number of reacting species from left to right in the reaction equation.

If we look at Manganese, its oxidation number was decreased from +7 on the left hand side to +2 on the right hand side. This implies that it gained five electrons. recall that reduction refers to electron gain.

If we look at carbon, its oxidation number increased from +3 on the left hand side to +4 on the right hand side. This indicates loss of one electron and oxidation refers to electron loss.

MnO₄⁻ was reduced and C₂O₄²⁻ was oxidized in the titration.

The balanced chemical equation for the reaction can be expressed as:

[tex]\mathbf{6H^+_{(aq0} + 2MnO_4^-_{(aq)} + 5H_2C_2O_4 _{(aq)} \to 10CO_{2(g)} +8H_2O_{(l)} + 2Mn^{2+}_{(aq)}}[/tex]

A redox reaction can be described by a variation in the oxidation number of reacting species in the chemical reaction equation from the reactant side to the product side

Oxidation takes place when a substance(atom, molecule, or compound) loses an electronReduction occurs when a substance gains an electron.

Let consider Mn in MnO₄⁻, its oxidation number was decreased from +7 on the reactant side to +2 on the product side. This shows a gain of additional five electrons.

Thus, MnO₄⁻ is reduced.

Also in C₂O₄²⁻, the oxidation number of carbon increases from +3 on the reactant side to +4 on the product side. Since an electron is lost, then oxidation  occurs at C₂O₄²⁻

What is meant by a polar molecule?

 A polar molecule is usually formed when the one end of the molecule is said to possess more positive charges and whereas the opposite end of the molecule has negative charges, creating an electrical pole.

What is a polar molecule example? Water (H2O) is a polar molecule. The bonds between hydrogen and oxygen are distributed so that the hydrogen atoms are both on one side of the oxygen atom rather than evenly spaced.Sodium Chloride (NaCl) which is an ionic compound acts as a polar molecule. Usually, the large difference in electronegativities in sodium and chlorine makes their bond polar.
