Answer:
When two atomic orbitals come together to form two molecular orbitals, one molecular orbital will be lower in energy than the two separate atomic orbitals and one molecular orbital will be higher in energy than the separate atomic orbitals.
Explanation:
<em>Which of the following statements is TRUE? </em>
- <em>Electrons placed in antibonding orbitals stabilize the ion/molecule.</em> FALSE. Electrons in the antibonding orbitals destabilize the ion/molecule.
- <em>The total number of molecular orbitals formed doesn't always equal the number of atomic orbitals in the set.</em> FALSE. The total number of molecular orbitals is always equal to the number of atomic orbitals in the set.
- <em>When two atomic orbitals come together to form two molecular orbitals, one molecular orbital will be lower in energy than the two separate atomic orbitals and one molecular orbital will be higher in energy than the separate atomic orbitals.</em> TRUE. The orbital with lower energy will be the bonding orbital and the one with higher energy will be the antibonding orbital.
- <em>A bond order of 0 represents a stable chemical bond.</em> FALSE. A chemical bond is stable if the bond order is higher than zero.
Answer:
Percent ionic character is defined as the ratio of a bond’s actual dipole moment to the dipole moment it would have if the electron were completely transferred from one atom to the other, multiplied by 100
Explanation:
The percent ionic character seeks to establish the amount of electrovalency in a particular compound. It simply compares the covalency i.e extent of shared electrons to the the electrons that are transferred.
It is given as the ratio of the acutal dipole moment to the dipole moment due to ionic character of the bond multiplied by 100:
Percent ionic character = μ_obs/μ_ionic x 100
Where μobs is the actual dipole moment and μ ionic is the dipole moment if the bonds were 100% ionic.
<u>Ans: 650 J = 155 calories</u>
<u>Given:</u>
Energy in joules = 650 J
<u>To determine:</u>
The energy in calories
<u>Explanation:</u>
1 joule = 0.2388 calories
Therefore, 650 joules = 0.2388 calories * 650 J/1 J = 155 calories
Proteins are organic molecules composed of Carbon, Hydrogen, Oxygen and Nitrogen.
