What is allotrope of carbon??​

Chemistry
1 answer:
solong [7]3 years ago
3 0
Carbon has several allotropes, or different forms in which it can exist. These allotropes include graphite and diamond, which have very different properties. Despite carbon's ability to make 4 bonds and its presence in many compounds, it is highly unreactive under normal conditions.

Why do canned baked beans last longer in a can than in air?
Alinara [238K]
Because when anything is exposed to air, it come in contact with bacteria which begin to break down the proteins in the beans. But when it’s in a can, it can’t get exposed to bacteria which means it won’t break down.

Hope this sheds some light ♥︎

According to valence bond theory, the minimum of the potential energy curve describing the interaction of H atoms in H2 correspo
tatuchka [14]

The interaction between the two atoms of H in H2 with the lower energy corresponds to a covalent bond between hydrogen's.

When the two atoms of H form a bond, they are overlapping the individual orbitals to form a new one. Every hydrogen has 1 electron which sits in a 1s orbital and then form one molecular orbital. The energy of H2 is lower than individual hydrogens because the electrostatic interaction between them.

Determine whether the following reaction is a Lewis acid/base reaction and if so, what is the Lewis acid: Fe3+(aq) + 6 CN−(aq) →
Aleonysh [2.5K]

Answer: It is a Lewis acid/base reaction, and Fe^{3+} is the Lewis acid.

Explanation:

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Fe^{3+} can readily accept electrons and thus act as a lewis acid which is short of electrons.

CN^- can readily lose electrons and thus act as a lewis base which has excess of electrons.

It is a Lewis acid/base reaction, and Fe^{3+} is the Lewis acid.

Which substance below is resonance stabilized by delocalized pi electrons?
mariarad [96]
If you do not this, I suggest brushing up on delocalization as well as sigma/pi bonds. Benzene is the only one of the 5 with any pi bonds, so this should be a relatively easy question if you are familiar with the concepts. I would search up a detailed (not to detailed though) explanation of both.

PLEASEEE HELPPP!! Due today!!!!
dolphi86 [110]

Answer:

B

Explanation:

A chemical reaction equation is balanced if the number of atoms of each element on the right hand side of the reaction equation is the same as the number of atoms of the same element on the left hand side of the reaction equation.

By inspection, the chemical reaction written in the question is a balanced chemical reaction equation.

However, the statement in option B that more molecules of N2 are needed to produce NH3 than molecules of H2 is a false statement since only one mole of N2 and three moles of H2 are required to produce NH3 according to the reaction equation as written in the question.
