Cl2(g) + 2KI --> 2KCl(aq) + I2(s)
Oxidation
The equation given is correctly balanced, because it contains the same numbers of each kind of atoms in the reactants as in the products.
A quadratic equation.
That's the equation.
That word "equals" in there makes it an equation.
The chemical equation is not balanced. A balanced equation would be: KOH + H2SO4 -> KHSO4 + H2O
This is a balanced chemical equation.
2H2 + O2 --> 2H2O
The balanced chemical equation is: CO2 + C → 2CO
The balanced chemical equation for the reaction is: Zn(s) + CuSO4(aq) -> ZnSO4(aq) + Cu(s)
The balanced chemical equation for the reaction C2H2 + H2 → C2H6 is: C2H2 + 2H2 → C2H6
The balanced chemical equation for hydrogen reacting with chlorine to form hydrogen chloride is: H2 + Cl2 → 2HCl.
The chemical equation is not balanced. It should be balanced as follows: H2 + Cl2 → 2HCl
The balanced equation is: C5H12 + 8O2 → 5CO2 + 6H2O. Therefore, the coefficient for oxygen in the balanced equation is 8.
The balanced chemical equation for Na reacts with H2SO4 is: 2Na + H2SO4 -> Na2SO4 + H2
The balanced equation for the reaction is: 2AgNO3 + 2NaClO3 -> 2NaNO3 + AgClO3
