How many moles of O are needed to combine with 0.223 mole of C to form the following compounds?

CO
CO2

Write the equations and balance them.

C + O2 --> CO2 is one. You do the other one.
Ona (1) mole C combines with 1 mole oxygen to form CO2; therefore, 0.223 mole C will use 0.223 moles oxygen.

To determine the number of moles of oxygen needed to combine with carbon in each compound, we need to examine the chemical formulas and balance the equations.

1. CO (carbon monoxide):
The formula for carbon monoxide is CO, which means it contains one carbon atom and one oxygen atom.

To balance the equation, we need to ensure an equal number of atoms on both sides. Since there is only one carbon atom, we need one oxygen atom.

Therefore, for every molecule of CO, we need 1 mole of oxygen.

2. CO2 (carbon dioxide):
The formula for carbon dioxide is CO2, which means it contains one carbon atom and two oxygen atoms.

Similar to before, we need to balance the equation. With one carbon atom, we now have two oxygen atoms.

Therefore, for every molecule of CO2, we need 2 moles of oxygen.

In summary:
- For CO (carbon monoxide): 1 mole of oxygen is needed.
- For CO2 (carbon dioxide): 2 moles of oxygen are needed.

Hence, to combine with 0.223 mole of carbon, we would require:
- For CO (carbon monoxide): 0.223 moles of oxygen.
- For CO2 (carbon dioxide): 0.446 moles of oxygen.
