is salt always soluble is water?
For example, salts of sodium, potassium and ammonium are usually soluble in water. Notable exceptions include ammonium hexachloroplatinate and potassium cobaltinitrite. Most nitrates and many sulfates are water-soluble
Answer:
Many ionic compounds exhibit significant solubility in water or other polar solvents. Unlike molecular compounds, salts dissociate in solution into anionic and cationic components. For example, salts of sodium, potassium and ammonium are usually soluble in water.Explanation:

what part of the atom canot have its part acuratly determined ill give brainlest hurry
Answer:
The answer to this question would be electron.
Electron is located on the outer side of the atom and constantly moving in an orbit so its location cannot be accurately determined. The cloud around the center of the atom is drawn to picture the orbit.
Neutron and proton located in the middle of an atom in a part that called nucleus. Nucleus location is kept at the center and it doesn't move.

Convert 20 cals to J
Answer: 83.68 J
Explanation:
1 cal=4.184 J
1×20=4.184×20
20cals=83.68 J
How can we write a chemical reaction that explains what happens during a chemical change?
Answer: When we represent a chemical reaction in terms of words, we write a word equation. For example, when hydrogen gas reacts with oxygen gas to form water, we can write a word equation for the reaction as follows: hydrogen + oxygen→ water To the left of the arrow, we have the 'before' situation.

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.

Is acetaminophen conductive in water?
Answer:
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.
What is acetaminophen ?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.

A volume is measured experimentally as
4.09 mL. What is the percent error, given
that the correct value is 4.13 mL?
Answer in units of %.
Answer:
The answer is 0.97 %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
0.97 %Hope this helps you

Which refers to the number of wavelengths that pass a fixed point in a second?
wavelength
O amplitude
frequency
O compression
Please hurry will give brainliest on 10 mins
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.
What is frequency ?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.

Why do isotopes of the same element have the same atomic size?
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.
What are Isotopes?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.
