You need to do something like that your self so sorry can help.
Units of the SI System
There are seven base units in the SI system:
the kilogram (kg), for mass
the second (s), for time
the kelvin (K), for temperature
the ampere (A), for electric current
the mole (mol), for the amount of a substance
the candela (cd), for luminous intensity
the meter (m), for distance
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.

A
Explanation:
In the scientific name limus polyphemus which the species is the classification group for polyphemus
Answer:
80g
Explanation:
2H2 + O2 —> 2H2O
MM of H2O = (2x1) + 16 = 2 + 16 = 18g/mol
Mass conc. of H2O from the balanced equation = 2 x 18 = 36g
MM of O2 = 16 x 2 = 32g/mol
From the equation,
32g of O2 reacted to produce 36g of H2O.
Therefore Xg of O2 will react to produce 90g of H2O i.e
Xg of O2 = (32x90)/36 = 80g
