To balance the chemical equation $C_{3}H_{8}+O_{2}\rightarrow CO_{2}+H_{2}O$, we need to ensure that the number of atoms of each element is the same on both sides of the equation.<br /><br />Let's start by balancing the carbon atoms. There are 3 carbon atoms in $C_{3}H_{8}$, so we need 3 $CO_{2}$ molecules on the right side to balance the carbon atoms.<br /><br />Next, let's balance the hydrogen atoms. There are 8 hydrogen atoms in $C_{3}H_{8}$, so we need 4 $H_{2}O$ molecules on the right side to balance the hydrogen atoms.<br /><br />Finally, let's balance the oxygen atoms. There are 6 oxygen atoms in 3 $CO_{2}$ molecules and 4 oxygen atoms in 4 $H_{2}O$ molecules, making a total of 10 oxygen atoms on the right side. Therefore, we need 5 $O_{2}$ molecules on the left side to balance the oxygen atoms.<br /><br />So, the balanced equation is: $C_{3}H_{8}+5O_{2}\rightarrow 3CO_{2}+4H_{2}O$<br /><br />Therefore, the correct coefficients are: a) $1,5,3,4$
