Given the unbalanced equation -C_(3)H_(6)(g)+ldots O_(2)(g)arrow ldots H_(2)O(g)+ldots CO_(2)(g) when the equation is completely balanced using the smallest whole numbers, the coefficient of Oz 5 2 3 10

To balance the given chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.The unbalanced equation is: Let's balance it step by step:1. **Balance the carbon (C) atoms:** - There are 3 carbon atoms in . - Therefore, we need 3 molecules to have 3 carbon atoms on the right side. 2. **Balance the hydrogen (H) atoms:** - There are 6 hydrogen atoms in . - Therefore, we need 3 molecules to have 6 hydrogen atoms on the right side. 3. **Balance the oxygen (O) atoms:** - On the right side, we have oxygen atoms from and oxygen atoms from , making a total of 9 oxygen atoms. - Therefore, we need molecules to provide 9 oxygen atoms on the left side. 4. **Adjust to the smallest whole numbers:** - Multiply all coefficients by 2 to eliminate the fraction: Now, the equation is balanced: The coefficient of is 9. Therefore, the correct answer is not listed among the provided options.
