Which of the following statements is not true regarding molecular orbital theory? O Bonding molecular orbitals have lower energy
pychu [463]

Answer:

Option c, Two atomic orbitals combine to form one molecular orbital

Explanation:

Molecular orbitals are formed by linear combination of atomic orbitals.

Some of the important facts of molecular orbital theories are as follows:

  • No. of the molecular orbitals formed are equal to the no. of atomic orbitals participated.
  • Half of the molecular orbitals are bonding molecular orbitals and half of the molecular orbitals are anti bonding molecular orbitals.
  • Anti bonding molecular orbitals have energy higher than participating atomic orbitals.
  • Bonding molecular orbitals have energy lower than participating atomic orbitals.
  • Molecular orbitals are that region in the molecule where electrons are most likely to found.

So, among given, option c which is 'atomic orbitals combine to form one molecular orbital' is incorrect.

A student places three ice cubes in a beaker and allows them to partially melt. if she measures the temperature of the water in
atroni [7]

She will most likely observe that the temperature does not change during melting because the heat absorbed is used to overcome intermolecular forces rather than to increase the kinetic energy of the particles if she measures the temperature of the water in the beaker.

Which of the following is true regarding nuclear fission and nuclear fusion?
Zarrin [17]
<h2>Nuclear Fission and Nuclear Fusion - Option C</h2>

Nuclear fission and nuclear fusion both of these processes can provide energy. Nuclear fission is the process in which heavy nucleus splits into smaller parts. When they split into smaller particles then it releases energy.

On the other hand, nuclear fusion is the process in which small particles fuse together to form a heavy nucleus. With the formation of heavy nucleus, it also provides energy.

Therefore, both these processes release or provide energy.
