Answer:

Explanation:

The percentage error of a certain measurement can be found by using the formula

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual volume = 4.13 mL

error = 4.13 - 4.09 = 0.04

We have

[tex]p(\%) = \frac{0.04}{4.13} \times 100 \\ = 0.968523002...[/tex]

We have the final answer as

Answer:

The order is B, C, A.

Explanation:

When the liquid is first poured into the container, the entropy is still very high because there is a very large difference in color of the liquid. The more time passes, entropy becomes lower because the blue color liquid disperses through the rest of the container. So the entropy is the highest in B and lowest in A. At A the entropy is as close to 0 as it can be in this situation out of the three parts.

Yes, acetaminophen is conductive in water.

Explanation:

Have a nice day!

Acetaminophen is conductive in water and it is electrochemically active. It is used as an antipyretic drug.

Acetaminophen is an organic compound containing the amine functional group. One of the most popularly prescribed analgesic and antipyretic medications, acetaminophen (AC), is thought to be both effective and safe.

AC is not poisonous or harmful when used rationally, but an overdose or continued use may cause nephrotoxicity and severe hepatotoxicity. As a result, AC monitoring is crucial for drug safety.

Various conductometric measurements reported the fair conductivity shown by acetaminophen in water. The intermolecular interaction of acetaminophen in water make it conductive.

Answer:

60 hours

Explanation:

18.0 __15__ 9 __15__ 4.5 __15__ 2.25 __15__ 1.125g

15(4)= 60

Sodium-24 has a half-life of approximately 15 hours. If only one-eighth of the sodium-24 remain , then it has been passed in 60 hours. So option D is correct.

The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T₁ ÷ 2, and the decay constant is given by T₁/2 = 0.693/λ

According to radioactive decay law, the rate of decay of radioactive atoms at any instant is directly proportional to the number of atoms present at that instant.

dtd N ∝ N

dtd N = λ N

where, N is number of integrated nucleus present in the sample at any time t and λ is decay constant.

Thus ,option D 60 hours is correct.

Answer: 83.68 J

Explanation:

1 cal=4.184 J

1×20=4.184×20

20cals=83.68 J

Answer:

Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.

The atomic size of an element significantly depends on the number of protons. It is the characteristic property of isotopes that they possess the same number of protons which is responsible for the same atomic size.

Isotopes may be defined as one of two or more species of atoms of a chemical element that have the same atomic number and location in the modern periodic table with identical chemical behavior but with different atomic masses and physical properties.

In a more simple sense, isotopes are those elements that have the same atomic number but different atomic mass. The atomic number depends on the number of protons which remains constant in isotopes. So, the isotopic elements have identical atomic sizes.

Therefore, the isotopes of the same element have the same atomic size.

Answer:

frequency

Explanation:

The number of wavelengths that pass through a fixed point in a second is called the frequency of the wave. It has the unit of Hertz. Hence, option C is correct.

The term that refers to the number of wavelengths that pass a fixed point in a second is frequency.

Frequency is a fundamental concept in wave motion and is defined as the number of complete cycles of a wave that occur per unit time. For example, the frequency of a sound wave is measured in hertz (Hz) and is equal to the number of sound wave cycles that occur per second.

The higher the frequency of a wave, the more cycles occur in a given period of time. Wavelength, on the other hand, refers to the distance between two adjacent points on a wave that are in phase with each other, such as the distance between two crests or two troughs.

Wavelength and frequency are related, and the frequency of a wave is inversely proportional to its wavelength. As the frequency of a wave increases, its wavelength decreases.

Amplitude refers to the maximum displacement of a wave from its equilibrium position, while compression is a region in a longitudinal wave where the particles are close together. Hence, option C is correct.
