Describe the source of angle strain and torsional strain present in cyclopropane​

Answers

Answer 1

Explanation:

The angle strain arises from the compression of the ideal tetrahedral bond angle of 109.5° to 60°. The large torsional strain occurs since all CH bonds on adjacent carbons are eclipsed.

Answer 2

The lateral angle that decrease in the lateral angle from 109.5 to 60 degree so, these is the main source of angle strain and torsional strain present in cyclopropane.

What is angle and torsional strain?

Angle strain is the term for strain that results from departure from one or more ideal bond angles. Torsional strain is a chemical compound's resistance to bond twisting. Torsional strain between the bonds occurs when atoms separated by three bonds are arranged in an unstable staggered conformation rather than an eclipsed shape.

It exists in cyclopropane because its C-C-C bond angles must not exceed 60 degrees, which is less than the optimum bond angle of 109.5 degrees for tetrahedral carbon. It is the cause of these.

We are aware that three carbon atoms in a triangle plane break the cycle and cause each carbon to be sp3 hybridized. All carbon endeavors are sp3 hybridized, and we are aware that the sp3 hybrid angle is 109 degrees, 28 minutes at 109.5 degrees. But the single angle in cyclo-propane is only 60 degrees.

Personal strain results from the bending of bonds necessary to form a new molecule. The primary source of the angle strain and torsional strain found in cyclopropane is the decrease in lateral angle from 109.5 to 60 degrees.

HF (aq) + NHâ (aq) â NHâ⺠(aq) + Fâ» (aq) g

Answers

Answer:

HF is the acid

Explanation:

The Brønsted-Lowry theory defines the acids and bases in chemistry as follows:

An acid is the species that can donate a proton

A base can accept protons.

In the reaction:

HF(aq) + NH₃(aq) → NH₄⁺(aq) + F⁻(aq)

As you can see, HF can donate its proton to produce F⁻: HF is the acid

In the same way, NH₃ is accepting a proton, NH₃ is the base.

Objects that conduct electricity can easily carry an electrical charge. Which of the following materials best conducts electricity?
A. copper wire
B. plastic tubing
C. rubber sheets
D. cotton string

Answers

A. Copper wire
Copper carries electricity
Better

Answer:

copper wire!

Explanation:

Each copper atom has lost one electron and become a positive ion. ... The electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons, because they help copper to be a good conductor of heat and electricity. Copper, Silver, Aluminum, Gold, Steel and Brass are common conductors of electricity. When properly installed, it is the safest and most efficient metal to produce electricity. Copper is commonly used as an effective conductor in household appliances and in electrical equipment in general. Because of its low cost, most wires are copper-plated. For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.

Answers

Answer:

the answer is  c.

Explanation:

The number of moles of sodium chloride present in 0.5 L of 4 Molar NaCl(aq) is  2 moles. The correct option is a.

What are moles?

Moles are the quantity or amount of any substance. It is a measurement quantity.

The concentration of NaCl is 4 molar

The volume of the solution is 0.5 L is given.

To calculate the number of moles, we use the formula of molarity, in which moles are divided by the volume of the given solution. The formula is:

Molarity = moles/ volume

4 M = moles / 0.5 L

Putting the values in the given formula:

Moles = 4 x 0.5 L = 2 moles

Thus, the correct option is a. 2 moles is the number of moles of sodium chloride.

gene

Explanation:

DNA is divided into functional units called genes. A gene is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis

Answer:

coding for protein are called exons, and the noncoding regions separating the exons are called introns. Following transcription, these coding sequences must be joined together before the mRNAs can function. The process of removal of the introns and subsequent rejoining of the exons is called RNA splicing.

A chemistry student named Igor was performing a titration experiment. He used 500mL of 6M sulfuric acid, H2SO4(aq) to completely neutralize a 2.00 L solution of unknown concentration sodium hydrodixe, NaOH(aq). What is the concentration of the NaOH(aq) in molarity (M)?

Answers

Answer:

3 M

Explanation:

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

H2SO4 + 2NaOH —> Na2SO4 + 2H2O

From the balanced equation above, the following data were obtained:

Mole ratio of the acid, H2SO4 (nA) = 1

Mole ratio of the base, NaOH (nB) = 2

Next, the data obtained from the question. This include the following:

Volume of acid, H2SO4 (Va) = 500 mL

Molarity of acid, H2SO4 (Ma) = 6 M

Volume of base, NaOH (Vb) = 2 L

Molarity of base, NaOH (Mb) =?

Next, we shall convert 2 L to millilitres (mL). This can be obtained as follow:

1 L = 1000 mL

Therefore,

2 L = 2 L × 1000 mL /1 L

2 L = 2000 mL

Thus, 2 L is equivalent to 2000 mL.

Finally, we shall determine the molarity of the base, NaOH. This can be obtained as follow:

Volume of acid, H2SO4 (Va) = 500 mL

Molarity of acid, H2SO4 (Ma) = 6 M

Volume of base, NaOH (Vb) = 2000 mL

Mole ratio of the acid, H2SO4 (nA) = 1

Mole ratio of the base, NaOH (nB) = 2

Molarity of base, NaOH (Mb) =?

MaVa / M Vb = nA/nB

6 × 500 / Mb × 2000 = 1/2

3000 / Mb × 2000 = 1/2

Cross multiply

Mb × 2000 × 1 = 3000 × 2

Mb × 2000 = 6000

Divide both side by 2000

Mb = 6000 /2000

Mb = 3 M

Thus, the molarity of the base, NaOH is 3 M.

A biology experiment requires the preparation of a water bath at 37.08C (body temperature). The temperature of the cold tap water is 22.08C, and the temperature of the hot tap water is 55.08C. If a student starts with 90.0 g cold water, what mass of hot water must be added to reach 37.08C

Answers

Answer:

75 g

Explanation:

[tex]m_1[/tex] = Initial mass of water = 90 g

c = Specific heat of water

[tex]\Delta T_1[/tex] = Initial temperature difference = [tex](37.08-22.08)^{\circ}\text{C}[/tex]

[tex]m_1[/tex] = Mass of water to be added

[tex]\Delta T_2[/tex] = Final temperature difference = [tex](37.08-55.08)^{\circ}\text{C}[/tex]

Since, heat energy in the system is conserved we know

[tex]m_1c\Delta T_1+m_2c\Delta T_2=0\\\Rightarrow m_1c\Delta T_1=-m_2c\Delta T_2\\\Rightarrow m_2=-\dfrac{m_1\Delta T_1}{\Delta T_2}\\\Rightarrow m_2=-\dfrac{90(37.08-22.08)}{37.08-55.08}\\\Rightarrow m_2=75\ \text{g}[/tex]

The mass of water to be added to reach the desired temperature is 75 g.

What is electrical insulation?

An electrical insulation is used to prevent the passage of electricity through an object. The materials which does not conduct electrically at any condition is called insulators.

Insulators are used as protective envelopes over the conducting bodies to resist the electrical shock and shortage of electricity. The electrical wires of circuits are coated with insulating plastics throughout up to the terminals.

The terminals cannot be insulated because, the passage of electricity to external circuit can only be achieved by conducting ends otherwise insulation will resist the passage of electrons to the battery. Thus, option C is correct.

B. The electrons of iron have probable locations in a region of space around the nucleus.
C. Iron atoms combine with other atoms in whole number ratios to form compounds.
D. Chemical reactions that involve iron do not create new atoms of iron.

Answers

Answer:

The correct option is B

Explanation:

One of the claims of John Dalton's atomic theory is that atom is the smallest unit of matter (which suggests that there are no particles smaller than an atom in any matter). This claim has been disproved by the modern atomic theory which established that there are particles smaller than atom (called subatomic particles). These particles are electrons, protons and neutrons.

One of the modern atomic theory was by Neils Bohr, who proposed that electrons move in circular orbits around the central nucleus. Thus, the electrons of iron can also be said to be present in a region of space (circular path) around the nucleus. This proves that option B is the correct option as John Dalton's theory did not even recognize the electron(s) nor the nucleus.
