Rotational absorption lines from 1 H35Cl gas were found at the following wavenumbers (R. L. Hausler and R. A. Oetjen, J. Chem. Phys. 21, 1340 (1953)): 83.32, 104.13, 124.73, 145.37, 165.89, 186.23, 206.60, 226.86 cm−1 . Calculate the moment of inertia and the bond length of the molecule. Predict the positions of the corresponding lines in 2 H35Cl.

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

The answer will be c

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
