Balance the following chemical equation: (Remember to enter "1" where you have blanks after balancing) Cu2O +  C -->  Cu +  CO2

To balance the chemical equation Cu2O + C --> Cu + CO2, follow these steps:

1. Identify the number of atoms for each element on both sides of the equation.

On the left side (reactants), we have:

• 2 Copper (Cu) atoms
• 1 Oxygen (O) atom
• 1 Carbon (C) atom

On the right side (products), we have:

• 1 Copper (Cu) atom
• 2 Oxygen (O) atoms
• 1 Carbon (C) atom

2. Balance the Copper (Cu) atoms first. Since there are 2 Cu atoms on the left side and only 1 on the right side, we can put a 2 in front of Cu on the right side to balance the Cu atoms:

Cu2O + C --> 2Cu + CO2

Now, we have:

• 2 Copper (Cu) atoms on both sides
• 1 Oxygen (O) atom on the left side
• 3 Oxygen (O) atoms on the right side
• 1 Carbon (C) atom on both sides

3. Next, balance the Oxygen (O) atoms. There are 3 O atoms on the right side and only 1 on the left side. To balance the O atoms, we can put a 2 in front of Cu2O on the left side:

2Cu2O + C --> 2Cu + CO2

Now, we have:

• 4 Copper (Cu) atoms on the left side
• 2 Copper (Cu) atoms on the right side
• 2 Oxygen (O) atoms on both sides
• 1 Carbon (C) atom on both sides

4. Finally, balance the Copper (Cu) atoms again. There are 4 Cu atoms on the left side and only 2 on the right side. To balance the Cu atoms, we can put a 2 in front of Cu on the right side:

2Cu2O + C --> 4Cu + CO2

Now, the equation is balanced with:

• 4 Copper (Cu) atoms on both sides
• 2 Oxygen (O) atoms on both sides
• 1 Carbon (C) atom on both sides

So, the balanced chemical equation is: 2Cu2O + C --> 4Cu + CO2
