I think what you are thinking of is the decomposition of Hydrogen peroxide, which has the equation:
2H2O2 --> O2 + 2H2O which when balanced then equals 8.
2(H2O2) --> 2H2O +O2
|4*2|=8 -->|3*2|=6 +2= 8
That is the entire equation completed and balanced. Hope it helped!
The balanced equation for potassium reacting with chlorine to form potassium chloride is: 2K + Cl2 → 2KCl
you have to write... 2KI + Cl2 = 2KCl + I2
The balanced equation for the reaction is: 2Na2O + 2CO2 -> 2Na2CO3 This is a double displacement reaction, where the sodium from sodium oxide replaces the carbon in carbon dioxide to form sodium carbonate.
The balanced equation for sodium reacting with water to yield sodium hydroxide and hydrogen gas is: 2Na(s) + 2H2O(l) -> 2NaOH(aq) + H2(g)
Na2O + CO2 >> Na2CO3Balanced. Single displacement, I think. SYNTHESIS
No. There are two O's on the right side and three on the left. The balanced form is 2 H202 -> 2 H20 + 02. All of the O's are the letter 0 in this equation. All numbers are subscripts except the two 2's in front of the H's that have a space after them. I've taken college-level chemistry, so I remember how to do this.

If you had the equation of H2O2(aq) ==> H2O(l) + O2(g), it wouldn't be balanced, so is incorrect. If it were 2H2O2 ==> 2H2O + O2, then it would be balanced, and H2O2 would be an example of a disproportionation reaction, where H2O2 is both the oxidizing and reducing agent, i.e., the O is both oxidized and reduced to form H2O and O2. Not sure if this is what you are looking for as the question is rather vague.
you have to write... 2KI + Cl2 = 2KCl + I2
The balanced chemical equation for sulfur reacting with molecular chlorine to form sulfur dichloride is: S(s) + Cl2(g) → SCl2(l)
The balanced formula equation for the reaction where lithium reacts with chlorine gas to form lithium chloride is: 2Li(s) + Cl2(g) -> 2LiCl(s)
The balanced equation for this reaction is: N2(g) + 3H2(g) → 2NH3(g).
The coefficient of HCl in the balanced equation is 2. This is because the balanced equation shows that 1 molecule of CaCl2 reacts with 1 molecule of H2CO3 to form 1 molecule of CaCO3 and 2 molecules of HCl.
Potassium nitrate is too stable and so is silver for these two species to react. There is thus no balanced equation.
The balanced chemical equation for the reaction between iron and sulfur to form iron(II) sulfide is: Fe + S -> FeS This equation shows that one iron atom reacts with one sulfur atom to form one molecule of iron(II) sulfide.
The balanced chemical equation for the reaction between hydrochloric acid (HCl) and manganese (Mn) would be: 2HCl + Mn -> MnCl2 + H2 This equation shows that hydrogen chloride reacts with manganese to form manganese(II) chloride and hydrogen gas.
The balanced equation for the reaction between silicon dioxide (SiO2) and carbon (C) to form silicon carbide (SiC) and carbon monoxide (CO) is: SiO2 + 3C → SiC + 2CO
