The balanced chemical equation for the reaction C2H6 + O2 → CO2 + H2O is:
2 C2H6 + 7 O2 → 4 CO2 + 6 H2O
The balanced chemical equation for that reaction is: C2H6 + 7/2 O2 -> 2 CO2 + 3 H2O
No, the equation is not balanced. The correct balanced equation would be: 2Na + F2 -> 2NaF
The balanced equation for carbon plus water yielding carbon monoxide plus hydrogen is: C + H2O → CO + H2. This equation represents the reaction where carbon reacts with water to produce carbon monoxide and hydrogen gas. The equation is balanced with 1 carbon atom on each side and 2 hydrogen atoms on each side.
The balanced equation is: C5H12 + 8O2 → 5CO2 + 6H2O. Therefore, the coefficient for oxygen in the balanced equation is 8.
The chemical equation SiCl + Mg → MgCl2 + Si is not balanced. To balance it, you would need to adjust the coefficients to ensure that the number of atoms of each element is the same on both sides of the equation.
