The balanced equation is: C4H10 + 6.5 O2 → 5 H2O + 4 CO2
Explicação
## Step 1
The given equation is a combustion reaction where butane (C4H10) reacts with oxygen (O2) to produce water (H2O) and carbon dioxide (CO2). To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.
## Step 2
Start by balancing the carbon atoms. There are 4 carbon atoms in C4H10, so we need 4 CO2 molecules on the right side to balance the carbon atoms.
## Step 3
Next, balance the hydrogen atoms. There are 10 hydrogen atoms in C4H10, so we need 5 H2O molecules on the right side to balance the hydrogen atoms.
## Step 4
Finally, balance the oxygen atoms. There are 8 oxygen atoms in 4 CO2 molecules and 5 oxygen atoms in 5 H2O molecules, making a total of 13 oxygen atoms on the right side. Therefore, we need 13/2 = 6.5 O2 molecules on the left side to balance the oxygen atoms.
