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.

d. (Ala-Asp-Gly)5 or (Asn-Ser-His)5 at pH 3.0:

Answers

Answer:

The definition has been defined throughout the clarification segment below, as per the provided case.

Explanation:

Polypeptides were essential amino acids although therefore realize that those acids become charged individually, provide various R groups but have specific isoelectric positions as well.

The polypeptides could be divided by analysis of multiple isoelectric points including fulfilling the following, even though a protein always at the isoelectric point seems to have the end up losing money.

At pH 7, it would be very negatively (-) charged, although (Phe-Met)₃ is even less positive and therefore less reversible. This would be strongly positively (+) charge (equatorial) around pH 7, except for the amino as well as carboxyl-terminal, then (Gly)₂₀ which again is hourly rounding. Although the carboxylate categories of Asp compounds become partly protonated although neutral throughout (Ala-Asp-Gly)₅, around pH 3, although the imidazole categories of His compounds become completely protonated although covalently bonded throughout (Asn-Ser-His)₅.About pH 6.0, only certain polymers provide covalent bonds of polar Ser, however (Asn-Ser-His)₅ does have side bonds of polar Asn as well as partly protonated peptide bonds of His.

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.

Consider the reaction below. Which species is(are) the Brønsted-Lowry acid(s)?

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.

What is a segment of DNA that can code for?

Answers

Answer:

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.

What is the predominant intermolecular force in the liquid state of each of these compounds: hydrogen fluoride (HF), carbon tetrabromide (CBr4), and nitrogen trifluoride (NF3)? Force(s): Dipole-dipole Hydrogen Bonding Dispersion

Answers

Answer:

HF - hydrogen bonding

CBr4 - Dispersion

NF3 - Dipole-dipole

Explanation:

Hydrogen bonding occurs when hydrogen is covalently bonded to a highly electronegative atom such as fluorine, chlorine nitrogen, oxygen etc. Hence the dominant intermolecular force in HF is hydrogen bonding.

CBr4 is nonpolar because the molecule is tetrahedral and the individual C-Br dipole moments cancel out leaving the molecule with a zero dipole moment hence the dominant intermolecular force are the dispersion forces.

NF3 has a resultant dipole moment hence the molecules are held together by dipole-dipole interaction.

The predominant intermolecular force in the liquid state of the compounds are as follows:

HF - hydrogen bonding

HF - hydrogen bondingCBr4 - Dispersion

HF - hydrogen bondingCBr4 - DispersionNF3 - Dipole-dipole

Discussion:

Hydrogen bonding is a bonding characterized covalent bonding of hydrogen to a highly electronegative atom such as fluorine, chlorine nitrogen, oxygen etc.

In essence, the dominant intermolecular force in HF is hydrogen bonding.

Carbon tetrabromide, CBr4 is nonpolar because the molecule is tetrahedral and the individual C-Br dipole moments neutralise leaving the molecule with a zero dipole moment hence the dominant intermolecular force are the dispersion forces.

Nitrogen trifluoride, NF3 has its molecules held together by dipole-dipole interaction as a result of its resultant dipole moment.

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.
