How do you prepare 3 percent solution of hydrogen peroxide?
1 part of hydrogen peroxide out of 30% hydrogenperoxide bottle add 10 parts of distilled water
How do you prepare 3 percent of hydrogen peroxide from 30 percent of hydrogen peroxide?
Lets say you want an end volume of 500 ml of 3% peroxide. But you dont know how much 30% peroxide to use. Concentration1 X Volume1 = Concentration2 X Volume2 30/100 X unknown ml = 3/100 X 500 ml unknown ml = 50 ml 50ml of 30% added to pure 450 ml of water = 500 ml 3 % peroxide. · 3 years ago
How do you prepare 0.2 M hydrogen peroxide?
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.
How do you prepare hydrogen in a laboratory?
1. Zn + 2 HCl → ZnCl2 + H22. Treating of aluminum powder with NaOH or KOH solutions.2 Al + 6 H2O + 2 NaOH → 2 NaAl(OH)4 + 3 H2Aluminium2 Al + 6 H2O + 2 OH− → 2 Al(OH)−4 + 3 H2
If a hydrogen atom has a mass of 3 is it an isotope?
No, a hydrogen atom with a mass of 3 is not an isotope of hydrogen. Hydrogen isotopes include protium (mass 1), deuterium (mass 2), and tritium (mass 3).

How did the Shang and Egyptians prepare for the afterlife in the same ways?
In fact they did not prepare for the afterlife in the same ways.
How do you prepare hydrogen from water at home?
by the process of electrolysis

Can copper be used to prepare hydrogen by reaction with diluteacids?
No. Copper is below hydrogen in the electromotive series and therefore can not displace hydrogen from its compounds.
How can people prepare for disaster?
People can prepare for disaster in a variety of ways. Having a previously established plan, with escape routes, meeting points, and shelter places are all effective ways to prepare for disasters.
What type of gases are used to prepare Ammonia gas?
Nitrogen and hydrogen
What are 3 ways Jews get ready for Passover?
They,1. Clean their house2. Make sure there is no yeast in the house3. Prepare for the meal (Seder meal)
Why copper is not used to prepare hydrogen in the laboratory?
Copper is not typically used to prepare hydrogen in the laboratory because it is not reactive enough to displace hydrogen from water or acids. Other metals like zinc or aluminum are more commonly used for this purpose as they have a higher reactivity with water or acids.
What are some ways to prepare banana plantations?

3 ways of making hydrogen?
1. You can make hydrogen by passing an electrical current through water this separates the hydrogen and the oxygen from H2O. 2. Removal of hydrogen from hydrocarbons: CH4 + H2O → CO + 3 H2 3. From carbon monoxide: CO + H2O → CO2 + H2 4. Small scale production: reaction of zinc with acids, reaction of aluminum with sodium hydroxide. etc.
