Chemical reaction: HCl + Ba → BaCl₂ + H₂.

Oxidation reaction: Ba⁰ → Ba⁺² + 2e⁻.

Reduction reaction: 2H⁺ + 2e⁻ → H₂⁰.

Balanced chemical reaction: 2HCl + Ba→ BaCl₂ + H₂.

Barium (Ba) change oxidation number from 0 to +2 (lose electrons), barium is oxidized (reducing agent).

Hydrogen change oxidation number from +1 to 0 (gain electrons), it is reduced.

V 2 O 5 + Cl 2  VOCl 3 + O 2

rosijanka [135]

Answer: 3.5 moles V2O5

Explanation: First balance the chemical equation to find the stoichiometric factor between VOCl3 and V2O5

2 V2O5 + 6 Cl2 => 4 VOCl3 + 7 O2

So the mole to mole ratio is 2 moles V2O5 to 4 moles of VOCl3

Solution

7 moles VOCl3 x 2 moles V2O5 / 4 moles VOCl3 = 3.5 moles V2O5
