The following data are obtained from the vibronic spectrum of BeO for transitions from the electronic ground state to an excited state: 0 → 0: 10365.39 cm, 0 → 1:11475.62 cm-", 0→2: 12569.93 cm-,
1 → 0: 8901.73 cm, 2→ 7461.73 cm!

Determine ře, ře and te of the excited state, and V and full of the ground state.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
