Use the drawing of a molecular orbital energy diagram for clf (assume that the σp orbitals are lower in energy than the π orbitals.) to predict the bond order?

The bond order of the ClF molecule have to get from the molecular orbital energy level diagram.

The bond order in ClF is 1 with 2 pairs of lone pair of electron on both the atom.

The energy level diagram of the molecule is shown in the figure.

There are 2 electrons in the bonding orbital i.e. σp orbital and no electron in its corresponding anti bonding orbital.

Now we know the bond order of a molecule is [Electrons in boding orbital - electrons in anti bonding orbital]

Thus in this case [2-0] = 1.

There remains 2 pairs of non bonding electrons on Cl and F atom as shown in the diagram. The energy level of 2p valence electron of F atom will be lower than the 3p valence electron of Cl atom.  

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
