Explanation:

It is known that mathematically, 1 hectoliter is equal to 10,000 centiliters. As we are given 1.3902 hectoliters so, we will convert it into centiliters as follows.

                    1 hectoliter = 10,0000 centiliter

Centiliters present in 1.3902 hectoliters will be calculated as follows.

         1.3902 hectoliter \times \frac{10,000 centilieters}{1 hectoliter}

            = \frac{13902}{10,000} \times 10,000 centiliters

            = 13902 centiliters

Thus, we can conclude that there are 13902 centiliters in 1.3902 hectoliters.

A student is given a sample of a blue copper sulfate hydrate. He weighs the sample in a dry covered porcelain crucible and got a
Nata [24]

Answer:

There are present 5,5668 moles of water per mole of CuSO₄.

Explanation:

The mass of CuSO₄ anhydrous is:

23,403g - 22,652g = 0,751g.

mass of crucible+lid+CuSO₄ - mass of crucible+lid

As molar mass of CuSO₄ is 159,609g/mol. The moles are:

0,751g ×\frac{1mol}{159,609g} = 4,7052x10⁻³ moles CuSO₄

Now, the mass of water present in the initial sample is:

23,875g - 0,751g - 22,652g = 0,472g.

mass of crucible+lid+CuSO₄hydrate - CuSO₄ - mass of crucible+lid

As molar mass of H₂O is 18,02g/mol. The moles are:

0,472g ×\frac{1mol}{18,02g} = 2,6193x10⁻² moles H₂O

The ratio of moles H₂O:CuSO₄ is:

2,6193x10⁻² moles H₂O / 4,7052x10⁻³ moles CuSO₄ = 5,5668

That means that you have <em>5,5668 moles of water per mole of CuSO₄.</em>

I hope it helps!

It takes energy to ionize any atom. It takes progressively more and more energy for each successive electron that is removed and
IrinaVladis [17]

Answer:

Removal of Third Electron

Explanation:

a major jump is required to remove the third electron. In general, successive ionization energies always increase because each subsequent electron is being pulled away from an increasingly more positive ion.

Ionization energy increases from bottom to top within a group, and increases from left to right within a period.

Choose the statements about benzene that are correct.
FromTheMoon [43]

Answer:

All of the C-C bonds are actually identical,

The structure of the molecule is closed like a ring structure,

Explanation:

1) all benzene hydrocarbons are ChHp-2 ⇔ this is <u>false</u> the formula for benzene is C6H6 ( CnHn).

2)All C-C bonds share 2 pairs of electrons ⇔ <u>False </u>

There are not enough electrons to form double bonds on all the carbon atoms

3) Three C-C bonds share 2 pairs of electrons  ⇔ False

Since there are not enough electrons to form double bonds on all the carbon atoms, although the electrons do strengthen all of the bonds on the ring equally.

4) All of the C-C bonds are actually identical ⇔ <u>correct </u>

⇒The actual structure of benzene is a resonance hybrid, with six delocalised π-electrons.  (4n + 2 = π)

⇒Due to this structure with delocalised π-electrons, the structure of benzene is very stable and it's reactivity quite low.

⇒ All the C-C bonds of bezene have sp2-sp2 overlap on both sides, what makes them to form 3 π-bonds

5) The structure of the molecule is closed like a ring structure ⇔ <u>correct</u>

Since there are not enough electrons to form double bonds on all the carbon atoms, although the electrons do strengthen all of the bonds on the ring equally. This results in symmetric molecular orbital. The delocalisation of the electrons is also known as aromaticity or ring structure, what gives benzene a great stability.
