The Lewis structure for ozone contains a central oxygen atom that has a double bond to one oxygen atom and a single bond with the other oxygen atom. The resonance structure of the ozone is shown in the attached figure below.
What is the lewis structure of the ozone molecule?The oxygen molecule has a valency of -2. It can form two-sigma bonds or covalent bonds with the other atoms. Oxygen contains three lone pairs to form π bonds with other atoms. Ozone contains all three oxygen atoms and is a dihedral molecule with sp² hybridization.
Lewis structure is generally based on the octet rule which states that there should be eight electrons in the valence shell or orbit of an atom for a stable molecule.
The lone pair on the central oxygen atom repels the electrons in the two side bonds and adopt a bent molecular geometry. The expected geometry is the trigonal planar with a bond angle is 120°.
In an ozone molecule, six valence electrons for each molecule of Oxygen so the total number of valence electrons is 6 × 3 = 18. As both Oxygen atoms on the sides have the same electronegativity, therefore, the double bond keeps on shifting from both causing resonances.

A chunk of sulfur has a volume of 8.33 cm3. What is the mass of this sulfur? (Density of sulfur = 2.07 g/cm3.)
Explanation:
equations to note:
density= mass/volume
mass= volume *density
volume= mass/density
you have a volume- 8.33cm3
you have a density- 2.07 g/cm3
Answer:
8.33cm3 * 2.07g/cm3= 17.24g
mass= 17.24g

Due to the fact that electrons are delocalized in graphite, it is a good conductor of electricity. Carbon atoms in graphite form hexagonal layers and are in covalent bonds with three other carbon atoms. Due to this non-bond electron configuration, each carbon atom conducts electricity in the form of a delocalized electron.

what is the difference between cyclic compound and straight chain compound in hydrocarbons reaction
Explanation:
Cyclic Hydrocarbons
A cyclic hydrocarbon is a hydrocarbon in which the carbon chain joins to itself in a ring. A cycloalkane is a cyclic hydrocarbon in which all of the carbon-carbon bonds are single bonds. Like other alkanes, cycloalkanes are saturated compounds. Cycloalkanes have the general formula CnH2nCnH2n. The simplest cycloalkane is cyclopropane, a three-carbon ring.

What did Fermi mean when he said, "The reaction is self-sustaining"?
The reaction reached critical mass.
A spontaneous chain reaction had been accomplished.
The nuclear reaction was out of control.
The nuclear reaction could be controlled and maintained.
Answer:
The nuclear reaction could be controlled and maintained.
Explanation:
People had initiated a self-sustaining nuclear reaction--and then stopped it. He had released the energy of the atom's nucleus and controlled that energy.
Fermi's achievement in setting off the first self-sustaining nuclear chain reaction from his design of an atomic pile led to a new Age of the Atom. The controlled release of nuclear energy was now a reality
