3. Belance the following equation, when you are finished add up the coefficients and select the correct total underline ( )Fe_(2)O_(3)+underline ( )COarrow underline ( )CO_(2)+underline ( )Fe 12 9 14 8

To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.<br /><br />The given equation is:<br />Fe2O3 + CO → CO2 + Fe<br /><br />To balance the equation, we need to find the coefficients for each compound.<br /><br />Let's start with the iron (Fe) atoms. We have 2 Fe atoms on the left side and 1 Fe atom on the right side. To balance the Fe atoms, we need to put a coefficient of 2 in front of Fe on the right side.<br /><br />Fe2O3 + CO → CO2 + 2Fe<br /><br />Next, let's balance the oxygen (O) atoms. We have 3 O atoms on the left side and 2 O atoms on the right side. To balance the O atoms, we need to put a coefficient of 3 in front of CO on the left side.<br /><br />Fe2O3 + 3CO → CO2 + 2Fe<br /><br />Finally, let's balance the carbon (C) atoms. We have 3 C atoms on the left side and 1 C atom on the right side. To balance the C atoms, we need to put a coefficient of 3 in front of CO2 on the right side.<br /><br />Fe2O3 + 3CO → 3CO2 + 2Fe<br /><br />Now, let's add up the coefficients:<br /><br />1 (Fe2O3) + 3 (CO) + 3 (CO2) + 2 (Fe) = 9<br /><br />Therefore, the correct total is 9.
