What type of solvent would be required to dissolve nonpolar compounds?

Chemistry

mina [271]1 year ago

For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.

Answer:

Solvents composed of polar molecules, such as water, dissolve other polar molecules, such as table salt, while nonpolar solvents, such as gasoline, dissolve nonpolar substances such as wax.

Explanation:

In chemistry, a common rule for determining if a solvent will dissolve a given solute is "like dissolves like." Solvents composed of polar molecules, such as water, dissolve other polar molecules, such as table salt, while nonpolar solvents, such as gasoline, dissolve nonpolar substances such as wax.

Compare a mixture and a compound. How are they alike?
harina [27]

Answer:

1.Difference.

Mixtures are physically combined and can be separated by physical means while compounds are chemically combined and are separated by chemical means.

2.Mixtures do not have mixed boiling and melting points while compounds have mixed boiling and melting points.

2.Similarity.

Both mixtures and compounds are composed of two or more substances or elements combined.

Both can be separated.

A periodic table allows you to easily compare the properties of one element ( or a group of element to another element or group
AfilCa [17]
The statement above is TRUE.
The periodic table refers to the table of chemical elements, in which the elements are arranged in order of their atomic numbers in such a way that, similar elements appear in vertical columns. Elements in the same column usually have similar atomic structures and similar chemical properties. Thus, the periodic table allows one to easily compared the properties of one element to that of another one depending on the placement of the elements in the periodic table.<span />

9. Thallium-208 has a half-life of 3.053 min. How long will it take for 120 g of it to decay
damaskus [11]

Answer:

12.213 minutes will be taken for 120 g-Thalium-208 to decay to 75 grams.

Explanation:

Radioactive isotopes decay exponentially in time, the mass of the isotope (m(t)), in grams, is described by the formula in time (t), in minutes:

m(t) = m_{o}\cdot e^{-\frac{t}{\tau} } (1)

Where:

m_{o} - Initial mass of the isotope, in grams.

\tau - Time constant, in minutes.

In addition, the time constant associated with the isotope decay can be described in terms of half-life (t_{1/2}), in minutes:

\tau = \frac{t_{1/2}}{\ln 2} (2)

If we know that m(t) = 7.5\,g, m_{o} = 120\,g and t_{1/2} = 3.053\,min, then the time taken by the isotope is:

\tau = \frac{t_{1/2}}{\ln 2}

\tau = \frac{3.053\,min}{\ln 2}

\tau \approx 4.405\,min

t = -\tau \cdot \ln \frac{m(t)}{m_{o}}

t = -(4.405\,min)\cdot \ln \left(\frac{7.5\,g}{120\,g} \right)

t \approx 12.213\,min

12.213 minutes will be taken for 120 g-Thalium-208 to decay to 75 grams.
