Consider the combustion of propane: C_(3)H_(8)+5O_(2)arrow 3CO_(2)+4H_(2)O Which of the following unit factors below is correct? (Select all that may apply) There are 5 oxygen atoms reacting for every 3CO_(2) molecules produced. There are 10 oxygen atoms reacting for every four water molecules produced. There are 10 oxygen atoms reacting for every six oxygen atoms produced in CO_(2) There are 5 oxygen molecules reacting for every six oxygen atoms produced in CO_(2)

To determine which unit factors are correct, we need to analyze the given chemical equation:<br /><br />$C_{3}H_{8}+5O_{2}\rightarrow 3CO_{2}+4H_{2}O$<br /><br />Let's evaluate each statement:<br /><br />1. There are 5 oxygen atoms reacting for every $3CO_{2}$ molecules produced.<br /> - This statement is incorrect. The balanced equation shows that there are 5 oxygen molecules ($O_{2}$) reacting to produce 3 carbon dioxide ($CO_{2}$) molecules, which means there are 6 oxygen atoms reacting for every 3 $CO_{2}$ molecules produced.<br /><br />2. There are 10 oxygen atoms reacting for every four water molecules produced.<br /> - This statement is correct. The balanced equation shows that there are 5 oxygen molecules ($O_{2}$) reacting to produce 4 water ($H_{2}O$) molecules, which means there are 10 oxygen atoms reacting for every 4 water molecules produced.<br /><br />3. There are 10 oxygen atoms reacting for every six oxygen atoms produced in $CO_{2}$.<br /> - This statement is incorrect. The balanced equation shows that there are 5 oxygen molecules ($O_{2}$) reacting to produce 3 carbon dioxide ($CO_{2}$) molecules, which means there are 6 oxygen atoms reacting for every 6 oxygen atoms produced in $CO_{2}$.<br /><br />4. There are 5 oxygen molecules reacting for every six oxygen atoms produced in $CO_{2}$.<br /> - This statement is correct. The balanced equation shows that there are 5 oxygen molecules ($O_{2}$) reacting to produce 3 carbon dioxide ($CO_{2}$) molecules, which means there are 5 oxygen molecules reacting for every 6 oxygen atoms produced in $CO_{2}$.<br /><br />Therefore, the correct unit factors are:<br />- There are 10 oxygen atoms reacting for every four water molecules produced.<br />- There are 5 oxygen molecules reacting for every six oxygen atoms produced in $CO_{2}$.
