It is very clear: the compounds resulted from this reaction are water and oxygen.
The balanced symbol equation for hydrogen peroxide (H2O2) reacting with manganese dioxide (MnO2) is: 2H2O2 + MnO2 -> 2H2O + O2 + Mn
Using the equilibrium constant expression, (K = \frac{[products]}{[reactants]}), we can set up the equation as (0.62 = [H2O2] / ([O2] * [H2O])). Plugging in the given values, we get (0.62 = [H2O2] / (0.4 * 0.2)). Solving for [H2O2], we find the equilibrium concentration of H2O2 to be 0.62 * 0.4 * 0.2 = 0.0492.
The chemical symbol for hydrogen peroxide is H2O2
H2O2 is the chemical formula. Since hydrogen peroxide is not an element it does not have a symbol.
The balanced chemical equation for the decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2) is: 2 H2O2 -> 2 H2O + O2. This means that for every 2 moles of hydrogen peroxide, 2 moles of water and 1 mole of oxygen are produced.
The chemical equation for the decomposition of H2O2 is 2 H2O2 -> 2 H2O + O2. This shows that two moles of H2O2 are required to produce each mole of O2. By definition, a 0.500 M solution of H2O2 contains 0.500 moles of H2O2 in each liter of solution. Solutions are always homogeneous; therefore, 50,0 mL of such a solution will contain (0.500)(50.0/1000) or 0.0250 moles of H2O2. As noted in the first paragraph, this will produce half as many, or 0.0125, moles of O2. The gram molar mass of O2 is twice the gram atomic mass of oxygen, or 31.9988. Therefore, decomposition of this amount of H2O2 will produce 31.9988 X 0.0125 or 0.400 gram of O2, to the justified number of significant digits.
The balanced equation for this decomposition reaction is 2 H2O2 -> 2 H2O + O2.
H2O2 + 2 KI --> 2 KOH + I2
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 chemical formula equation for hydrogen peroxide is H2O2, which means it consists of two hydrogen atoms and two oxygen atoms.
There is no real "net ionic" equation, as KI is a catalyst that decomposes H2O2. The "slow step" is H2O2 + I- --> OI- + H2O The "fast step" is H2O2 + OI- --> H2O + I- O2 The overall is: 2 H2O2 --> 2H2O + O2
The equation as given can not be balanced, because it is incomplete: When hydrogen peroxide decomposes to produce water, it also produces oxygen. A proper, balanced equation for the reaction is 2 H2O2 -> 2 H2O + O2.
