How many moles of hydrogen gas can be produced if 0.78 moles of hydrochloric acid reacts with excess solid zinc according to the
White raven [17]

Answer:

The answer to your question is It will be formed 0.39 moles of H₂

Explanation:

Data

moles of H₂ = ?

moles of HCl = 0.78

moles of Zinc = excess

Balanced chemical reaction

              2 HCl  +  Zn  ⇒  1 H₂  +  ZnCl₂

Process

1.- Use proportions to solve this problem. Consider the coefficients of the balanced reaction.

               2 moles of HCl ---------------------- 1 mol of H₂

               0.78 moles of HCl -----------------  x

               x = (0.78 x 1) / 2

- Simplification

              x = 0.78 / 2

- Result

              x = 0.39 moles of H₂

Kruka [31]

Answer:

In a semiconductor, the bonding molecular orbitals that contain electrons are referred to as the valence band, while the antibonding orbitals that are completely empty are referred to as the conduction band.

The conduction band occupies a higher energy level than the valence band. The band gap is what separates the two orbitals.
