Because on one side you have two hydrogens and two oxygens and on the other side of the equation you have two hydrogens and only one oxygen.
The chemical equation is not balanced. A balanced equation would be: KOH + H2SO4 -> KHSO4 + H2O
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 chemical equation is not balanced. A balanced equation would be: KOH + H2SO4 -> KHSO4 + H2O
This is a balanced chemical equation.
2H2 + O2 --> 2H2O
The correct answer 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
Cl2(g) + 2KI --> 2KCl(aq) + I2(s)
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 chemical equation is 2Na + H2SO4 --> Na2SO4 + H2
The balanced equation for the reaction is: 2AgNO3 + 2NaClO3 -> 2NaNO3 + AgClO3
