Sure! I can help you balance these equations.
1. AI + CuO → AI2O3 + Cu
To balance this equation, let's start by counting the number of atoms on each side of the equation.
On the left side, we have:
1 AI atom
1 Cu atom
1 O atom
And on the right side, we have:
2 AI atoms
3 O atoms
1 Cu atom
To balance the AI atoms, we need to put a coefficient of 2 in front of AI on the left side:
2 AI + CuO → AI2O3 + Cu
This gives us:
2 AI atoms
1 Cu atom
1 O atom on the left side
Now, let's balance the oxygen atoms. Since we have 3 O atoms on the right side, we need to put a coefficient of 3/2 in front of CuO on the left side.
Finally, the balanced equation is:
2 AI + (3/2) CuO → AI2O3 + Cu
2. Fe2O3 + C → Fe + CO2
Again, let's count the number of atoms on each side of the equation.
On the left side, we have:
2 Fe atoms
3 O atoms
And on the right side, we have:
1 Fe atom
2 C atoms
2 O atoms
To balance the Fe atoms, we put a coefficient of 2 in front of Fe on the right side:
Fe2O3 + C → 2Fe + CO2
Now, let's balance the O atoms. Since we have 3 O atoms on the left side and 2 O atoms on the right side, we put a coefficient of 3/2 in front of CO2 on the right side:
Fe2O3 + C → 2Fe + (3/2) CO2
3. SO2 + O2 → SO3
To balance this equation, we count the number of atoms on each side.
On the left side, we have:
1 S atom
2 O atoms
And on the right side, we have:
1 S atom
3 O atoms
To balance the O atoms, we put a coefficient of 3/2 in front of SO2 on the left side:
(3/2) SO2 + O2 → SO3
Finally, the balanced equation is:
3 SO2 + 2 O2 → 3 SO3
I hope this helps you balance the equations! Let me know if you have any further questions.
