B. 2-fluorobutane
C. 1-fluorobutane
D. 1-fluoropentane

Answers

Answer:

The correct answer is (C)

Which is "1-fluorobutane"

Explanation:

Hope this helped if so please leave a "Rating" and "Like" and MARK me Brainliest if it was the BEST answer! THANKS! :)

The name of the hydrocarbon CH3CH2CH2CH2F is 1-fluorobutane.

In naming organic hydrocarbons, we count the number of the parent chain family. Here, we have an alkane with 4 carbons, which means that the parent chain is a family of alkane. The fourth compound in the family of an alkane is butane.

Afterwards, we will determine if there is any substituent attached to any of the carbon atoms in the chain and rank them in a way such that we have the lowest possible number.

Here, the fluorine is attached to the first carbon atom. So, it becomes 1-fluorobutane.

In the reaction shown below, which substance is oxidized?
2Na + CuSO4 → Na2SO4 + Cu
A. Na
B. Na2SO4
C. Cu
D. CuSO4

Answers

Answer:

Na

Explanation:

Because sodium loses one electron and becons Na+ and sodium oxidizes

Los of electron is oxidation

Na is oxidised in the given reaction 2Na + CuSO[tex]_4[/tex] → Na[tex]_2[/tex]SO[tex]_4[/tex] + Cu. Therefore, the correct option is option A.

What is oxidation?

When the oxidation state of either a molecule, atom, or ion increases, this is referred to as oxidation. The inverse process is termed reduction, and it happens when electrons are gained when the oxidation status of such an atom, molecule, as well as ion lowers.

When a chemical species oxidizes, its oxidation state rises. Oxidation does not always need the presence of oxygen! The phrase was first used when oxygen induced electron loss inside a process. The present definition is broader.  Na is oxidised in the given reaction 2Na + CuSO[tex]_4[/tex] → Na[tex]_2[/tex]SO[tex]_4[/tex] + Cu.

Therefore,  Na is oxidised in the given reaction 2Na + CuSO[tex]_4[/tex] → Na[tex]_2[/tex]SO[tex]_4[/tex] + Cu. The correct option is option A.

None these is qualitative data

The sound of a person's voice

The weight of person

The hair color of a person

The body temperature of a person

Answers

Answer:

The hair color of a person

Explanation:

The correct answer would be the hair color of a person.

Qualitative data are data that cannot be measured with any instrument but can only be used to characterize. Unlike quantitative data, these kinds of data can only be observed and recorded but cannot be assigned numerical values, except if coded.

The sound of a person's voice can be quantitative on one hand and qualitative on the other. The intensity of a sound can be measured using a decibel meter and quantitatively assigned a figure, whereas, the quality of the sound can only be characterized and not measured.

Both the weight and the body temperature of a person can be measured using a weighing balance and a thermometer respectively and hence, are considered to be quantitative data when collected.

The color of the hair of a person cannot be measured but can only be observed and characterized. Hence, hair color data constitute qualitative data.

If you were to add glucose to catalase instead of hydrogen peroxide, would bubbles be produced?

Answers

Answer:

No, bubbles would not be produced.

Explanation:

Catalase is an enzyme that catalyses the decomposition of hydrogen peroxide into water (H2O) and oxygen gas (O2). Since oxygen (O2) is a gas, it is physically noticeable as BUBBLES. However, catalase as an enzyme is substrate-specific i.e. it solely acts/breaks down on hydrogen peroxide.

Hence, If one were to add glucose to catalase instead of hydrogen peroxide, oxygen gas observed as BUBBLES will not be produced because catalase will not act on glucose.


What is electronegativity?
Explain the periodic trend -
what is it, why is it that way

Answers

Answer:

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.

Explanation:

Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. ... These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements

Answers

Answer:

2C₂H₆ +  [7]O₂     →      [4]CO₂ + [6]H₂O

Explanation:

Chemical equation:

C₂H₆ +  O₂     →      CO₂ + H₂O

Balanced chemical equation:

2C₂H₆ +  7O₂     →      4CO₂ + 6H₂O

Step 1:

2C₂H₆ +  O₂     →      CO₂ + H₂O

Left hand side                      Right hand side

C = 4                                     C = 1

H = 12                                    H = 2

O = 2                                     O = 3

Step 2:

2C₂H₆ +  O₂     →      4CO₂ + H₂O

Left hand side                      Right hand side

C = 4                                     C =  4

H = 12                                    H = 2

O = 2                                     O = 9

Step 3:

2C₂H₆ +  O₂     →      4CO₂ + 6H₂O

Left hand side                      Right hand side

C = 4                                     C =  4

H = 12                                    H = 12

O = 2                                     O = 14

Step 4:

2C₂H₆ +  7O₂     →      4CO₂ + 6H₂O

Left hand side                      Right hand side

C = 4                                     C =  4

H = 12                                    H = 12

The trachea, also called the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi. At the top of the trachea the cricoid cartilage attaches it to the larynx. The trachea is formed by a number of horseshoe-shaped rings, joined together vertically by ligaments over their substance and by the trachealis muscle at their ends. The epiglottis closes the opening to the larynx during swallowing.

for each pair of compounds below , identify the one that would be expected to have more ionic character.explain you choice. (a)NaBr or HBr (b)BrCl or FCl​

Answers

Answer:

a)NaBr

b)FCl

Explanation:

To identify which compound is more ionic we will calculate the electronegativity difference.

A) NaBr

Electronegativity of Na = 0.93

Electronegativity of Br = 2.96

Electronegativity difference = 2.96- 0.93 = 2.03

HBr

Electronegativity of H = 2.2

Electronegativity of Br = 2.96

Electronegativity difference = 2.96 - 2.2 = 0.76

NaBr have more ionic character because of large electronegativity difference.

B) BrCl

Electronegativity of Cl = 3.16

Electronegativity of Br = 2.96

Electronegativity difference = 3.16 - 2.96 = 0.2

FCl

Electronegativity of F = 3.98

Electronegativity of Br = 2.96

Electronegativity difference = 3.98 - 2.96 = 1.02

FCl have more ionic character because of large electronegativity difference.

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question

2.47 L = 2470 mL

We have

[tex]P_2 = \frac{765 \times 2.78}{2470} = \frac{2142}{2470} \\ = 0.867206...[/tex]

We have the final answer as
