Final answer:
To balance the combustion reaction 2 C4H10 + Y O2 ⟶⟶ 8 CO2 + Z H2O, Y must be 13 and Z must be 8.
Step-by-step explanation:
To balance the combustion reaction 2 C4H10 + Y O2 ⟶⟶ 8 CO2 + Z H2O, we need to determine the values for Y and Z. First, let's balance the carbon atoms by multiplying C4H10 by 2 to get 8 carbon atoms on both sides of the equation.
The balanced equation becomes: 4 C4H10 + Y O2 ⟶⟶ 16 CO2 + Z H2O. Next, let's balance the hydrogen atoms by multiplying H2O by 8 to get 16 hydrogen atoms on both sides. The final balanced equation is: 4 C4H10 + Y O2 ⟶⟶ 16 CO2 + 8 H2O. Therefore, Y = 13 and Z = 8.
