Oh, dude, preparing 0.2 M hydrogen peroxide is like making lemonade, but with a bit more chemistry. You just take the concentrated hydrogen peroxide solution and dilute it with water until you reach a concentration of 0.2 M. It's not rocket science, just mix and measure, like following a recipe for a boring science experiment.
When the Maganese Dioxide (black powder) was added to the Hydrogen Peroxide (clear), it bubbled.It creates Water and Oxygen gas.The reaction is Decomposition.Hydrogen Peroxide --> Water + Oxygen2Hâ‚‚Oâ‚‚ --> 2Hâ‚‚O + Oâ‚‚When you write the reaction, make sure you put manganese dioxide over the yield symbol because it is a catalyst.Manganese dioxide catalyzes the decomposition of hydrogen peroxide, to Water and oxygen:2 H2O2 ---MnO2---> 2 H2O + O2
To calculate the amount of hydrogen peroxide (H2O2) needed to make a 1.33 molal solution in 1500 ml of water, you first need to convert the volume of water to grams. Since the density of water is 1.0 g/ml, 1500 ml of water is equal to 1500 grams. Next, calculate the moles of H2O2 needed using the molality formula (molality = moles of solute / mass of solvent in kg). Then convert the moles to grams by multiplying by the molar mass of H2O2 (34.02 g/mol).
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.
The molar mass of sodium hydroxide (NaOH) is approximately 40 g/mol. To prepare a 0.10 M solution in 100 mL, you would need 1.0 g of NaOH. This can be calculated using the formula: mass (g) = molarity (M) x volume (L) x molar mass (g/mol).
To calculate the mass of a hydrogen peroxide (H2O2) solution, you need to know the volume of the solution and its concentration (usually given in % or M). Use the formula: mass = volume x (concentration/100) x density of H2O2 solution. The density of the solution can vary based on its concentration, so check a reference source for the specific density value.
Give it hydrogen peroxide. It will make them throw up. But, call the vet first.

The energy required to break the oxygen-oxygen bond in hydrogen peroxide is about 498 kJ/mol. This corresponds to light in the ultraviolet range, with wavelengths shorter than about 250 nm. Light of longer wavelengths, such as in the visible or infrared range, would not provide sufficient energy to break the bond.
