1. Balanced Chemical Equation:
The balanced chemical equation for the reaction of carbon (C) with oxygen (O2) to form carbon dioxide (CO2) is:
C + O2 → CO2
2. Mole Ratio:
The balanced equation shows that 1 mole of carbon reacts with 1 mole of oxygen to produce 1 mole of carbon dioxide.
3. Converting Molecules to Moles:
* Avogadro's Number: There are 6.022 x 10^23 molecules in 1 mole of any substance.
* Calculate moles of oxygen: 14 molecules of oxygen / (6.022 x 10^23 molecules/mole) = 2.33 x 10^-23 moles of oxygen
4. Determining Moles of Carbon:
Since the mole ratio is 1:1, we need the same number of moles of carbon:
* Moles of carbon: 2.33 x 10^-23 moles of oxygen = 2.33 x 10^-23 moles of carbon
5. Converting Moles to Atoms:
* Calculate carbon atoms: 2.33 x 10^-23 moles of carbon * (6.022 x 10^23 atoms/mole) = 14 carbon atoms
Answer: 14 carbon atoms react with 14 molecules of oxygen to form carbon dioxide.
