<u>Answer:</u> The correct answer is No solution.

<u>Explanation:</u>

We are given:

Given mass of thiophene for the experiment = 90.00 g

12.3% w/w solution of thiophene

This means that 12.3 g of thiophene is present in 100 g of solution

Applying unitary method:

If 12.3 g of thiophene is present in 100 g of solution

So, 90.00 g of thiophene will be present in \frac{100g}{12.3g}\times 90.00g=731.7g of solution

Converting it into kilograms:

1 kg = 1000 g

So, 731.7 g = 0.7317 kg

As the given amount of solution is 0.50 kg which is less than the required amount.

Thus, there is not enough solution the student should use.

The bond between which two atoms has the greatest degree of polarity
Alenkasestr [34]

Answer:

By comparing  the bonds between C-H and O-H, the O-H bond has the greatest degree of polarity.

Explanation:

Based on bond electronegative values which is a measure of the ability of a atom in a chemical bond to pull the shared electrons closer to its self.

The electronegativity of an element characterizes the elements chemical reaction.

From the available bonds

Oxygen has an electronegativity value of 3.44 and Carbon 2.55, while  Hydrogen has an electronegativity value of  2.20

Therefore the bond between carbon and hydrogen is much less polar than between oxygen and hydrogen.

The bond between oxygen and hydrogen has the greatest polarity.

Answer:

The parts of an atom are<em><u> protons, electrons, and neutrons.</u></em>

A proton is positively charged and is located in the center or nucleus of the atom.

Electrons are negatively charged and are located in rings or orbits spinning around the nucleus.

The number of protons and electrons is always equal.
