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.
I believe the answer would be 2 because, assuming the substance is water, at 50 degrees Celsius it whole be liquid, 100 degrees celsius is its boiling point and at 150 degrees Celsius water is steam.
Answer: the answer is a i suppose
Explanation:
I would say c . isotope mass both varies in neutron numbers and its weighted by its relative abundance to give the average atomic mass. <span />
