Balance each reaction and match it to the sum of the coefficients of the balanced reaction. For example, sum of coefficients of 2 H2 + O2 → 2 H2O is 2 + 1 + 2 = 5. Please watch the video Sum of Coefficients for more details. If you are having trouble with the exercise, this video will help. < 4 6 12 5 10 13 18 1. 2. 3. 4. 5. 6. 7. 02 → 03 V205 + Ca → CaO + V Screen Reader: V205 + C a → Ca O +V H2SO4 + HI → H2S + 12 + H2O Screen Reader: H2SO4 + HI→ H2S + 12 + H2O V205 + HCI → VOCI3 +H2O Screen Reader: V205 + HCI → VO C13 +H2O Al2O3 + C +N2 → AIN + CO Screen Reader: Al2O3 + C +N2 → A IN + CO Li2O + H2O → LiOH Screen Reader: Li 20 + H2O → Li OH NH4V03 → V205 + NH3 + H2O Screen Reader: N H4V 03 → V205 + NH3 + H2O
