Question

If 0.4 moles of carbon are allowed to react with 0.6 moles of molecular oxygen, how many moles of CO2 are formed?

Answer 1

We know that for every mole of Carbon, we need 2 moles of oxygen to created Carbon Dioxide with every particle we have. So its a 1:2 ratio, carbon to oxygen
If we have 0.4 moles of carbon, we would need 0.8 moles of oxygen to maximize our carbon usefully, but we don't have that much oxygen. So, double down on oxygen, which is 0.3. So we can use 0.3 moles of carbon and 0.6 moles of oxygen to create 0.3 moles of CO2

Answer 2

Step-by-step explanation:

The given reaction will be as follows.

`C + O_(2) \rightarrow CO_(2)`

Therefore, according to this equation 1 mole of carbon is reacting with 1 mole of oxygen to give 1 mole of carbon dioxide.

Hence, 0.4 mole of carbon will react with 0.4 mole of oxygen atom which will result in the formation of 0.4 mole of carbon dioxide.

Therefore, carbon is the limiting reagent and oxygen is the excess reagent.

Thus, we can conclude that for the given reaction 0.4 moles of
`CO_(2)` are formed.
