Therefore, 2 x 500 000 = 1 000 000 moles of aluminium is produced EXAMPLE 1 EXAMPLE 2 VO 2+ → VO 2 + V +4 V +5 BrO 3-→ Br+5 Br 0 VO 2+ → VO 2 + V already balanced 2 BrO 3-→ 2 Br on right so need 2 BrO VO 2+ → VO 2 + + e-V becomes 1 more positive so 1 electron lost 2 BrO 3 + 10 e 2x Br become 5 more negative so 10 electrons gained VO 2+ + H 2O → VO 2 + + e-1 less O on left so add 1 H 2O on the left Dec 12, 2024 · 1.
