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

CO
CO2

To determine the number of moles of oxygen required to combine with a given amount of carbon, we need to first look at the balanced chemical equation for the formation of each compound.

1. CO:
The balanced equation for the formation of carbon monoxide (CO) is:
C + 0.5O2 -> CO

From the equation, we can see that for every 1 mole of carbon (C) that reacts, we need 0.5 moles of oxygen (O2). Therefore, to find the number of moles of oxygen needed to combine with 0.223 moles of carbon (C), we can use the ratio:

0.223 moles C × (0.5 moles O2 / 1 mole C) = 0.1115 moles O2

So, for the formation of CO, 0.1115 moles of oxygen (O2) are needed.

2. CO2:
The balanced equation for the formation of carbon dioxide (CO2) is:
C + O2 -> CO2

From the equation, we can see that for every 1 mole of carbon (C) that reacts, we need 1 mole of oxygen (O2). Therefore, to find the number of moles of oxygen needed to combine with 0.223 moles of carbon (C), we can use the ratio:

0.223 moles C × (1 mole O2 / 1 mole C) = 0.223 moles O2

So, for the formation of CO2, 0.223 moles of oxygen (O2) are needed.

In summary:
- 0.1115 moles of oxygen (O2) are needed for the formation of CO.
- 0.223 moles of oxygen (O2) are needed for the formation of CO2.
