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.
Mass of hydrogen = 1 g/mol Mass of oxygen = 16 g/mol There are 2 hydrogen in H2O2 and 2 oxygen in H202, so (1x2) + (16x2) = 34 g/mol
30 ml to 470 ml of water
If the density is 1.0 g/ml, one liter of the solution will weigh 1000 grams. 3.0 % of this mass or 30 grams of it is constituted of H2O2. The molar mass of H2O2 is 2 (1.008 + 15.999) = 34.014. The molarity of this solution is therefore 30/34.014 = 0.88, to the justified number of significant digits.
It stands for Hydrogen peroxide.A liquid in room temperature.
H2O2 (Hydrogen Peroxide) is broken down by Catalase [an enzyme of the Peroxidase family], produced by every living animal cell. So yes.
H2O2 is dissociate into water and oxygen.So fomula is H2O+O
Catalyst.
30% h2o2+h2so4
H2O2 + 2 KI --> 2 KOH + I2
H2o2 is used to give stress. The is also called hydrogen peroxide solution.
Mass of hydrogen = 1 g/mol Mass of oxygen = 16 g/mol There are 2 hydrogen in H2O2 and 2 oxygen in H202, so (1x2) + (16x2) = 34 g/mol
H2o2 --> h20 + o2
The hydrogen peroxide is both oxidized and reduced, to produce water and elemental oxygen.
The hydrogen peroxide, H2O2 , is being decomposed into water and oxygen gas (the bubbles).
