Explain whether co2 (o = c = o) is an ionic or a covalent compound. why does this arrangement satisfy all atoms involved?
1 answer:
Carbon dioxide (CO2) is a covalent compound because it is composed of carbon and oxygen. Herein both the elements i.e. C and O are non-metals.
These elements share the electrons. When electrons are shared, each atom will contain 8 electrons in the outer shell. Due to this, all the atoms of the CO2 will become stable and they will have a completed outer shell.
The lewis structure of CO2 is shown below:

There are one antibonding molecular orbitals present in molecular orbital model of c.
The cyclobutadiene has a pi system comprised of four individual atomic p - orbital and thus should have a four pi molecular orbitals. The compound is the prototypical antiaromatic hydrocarbon with 4 - electrons . Its rectangular structure is the result of jahn teller reaction which disorder the molecule and lowers its symmetry , converting the triplet to a singlet ground state. It is a small annulene . The delocalisation energy of the
electrons of the cyclobutene is predicted to be zero .

Answer : The pressure after the temperature change is, 0.752 atm
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
or,
where,
= initial pressure = 0.82 atm
= final pressure = ?
= initial temperature =
= final temperature =
Now put all the given values in the above equation, we get:
Thus, the pressure after the temperature change is, 0.752 atm
