Hydrogen Peroxide is expressed as H2O2, so you would assume that the molecular density would require you to only utilize 50 grams of hydrogen peroxide in order to get the required oxygen. However, Oxygen is a heavier Atomic Mass than Hydrogen, and therefore would require a slightly lower total of H2O2 in order to get the amount of oxygen required. by taking the atomic weight of both atoms, dividing the weights to find the percentage of the H2O2 that is Oxygen, you will be able to tell how much of the original substance you will need to divide in order to get the oxygen.

(For this answer, I'm assuming the question means diatomic hydrogen as it exists in nature. If you know otherwise, you may re-evaluate by substituting H2 with 2H, but the answer should be the same either way).

Let's do this step by step. We have H2 and O2. and we want water...

H2 + O2 ---> H2O Okay, that works. But we need to balance it...

2H2 + O2 ---> 2H2O Good.

We have as much O2 as we want...so really we want to know, how much H2 goes into each H2O? Obviously, it's 1. But for more complex questions, setting it out as above can help you.

Importantly, it lets you see that if you use 1 mol of H2, you get 1 mol of H2O. Important!

H2 weights 2g per mole.

H2O weights 16g per mole.

So for every 2g of H2 we put in, we get 16g of water back. Rounding down, for every 1g of H2 we put in, we get 8g of water back. So our mass of water will be 8 times the mass of hydrogen put in.

We have 100g of H2. Times this by 8.

800g of H2O!

The atomic mass of Oxygen is about 16. Water contains 1 oxygen atom.

The Atomic mass of hydrogen is about 1. Water contains two hydrogen atoms.

Therefore in water by mass the proportion of hydrogen to oxygen is 2/16 or 1/8

This means that in 100 grams of water there is 12.5 grams of hydrogen and 87.5 grams of Oxygen.

It depends on the conditions. Under "normal" conditions... hydrogen, oxygen, reasonable Earthly surface temperatures and pressures, no catalysts... much, much less than one.

Mix hydrogen peroxide and liver?

The enzyme in the liver (catalase) decomposes the hydrogen peroxide (H2O2) into water and oxygen molecules.


Is hydrogen peroxide a mixture?

It's a combination of 2 hydrogen and 2 oxygen molecules. H2O2


Why does having 2 hydrogen molecules make water instead of peroxide?

Water is H2O and hydrogen peroxide is H2O2 ; both of these molecules have two hydrogen atoms. It is the number of oxygen atoms which varies.


What happens when manganese dioxide is added to hydrogen peroxide and why was manganese dioxide added to the test tube containing hydrogen peroxide?

Yes, it would bubble because the bubbles are the result of the breakdown of two hydrogen peroxide molecules into oxygen and two water molecules.


What is produced when hydrogen peroxide is broken down?

When two molecules of hydrogen peroxide break down, one molecule of water and one molecule of diatomic oxygen are produced.


What does Hydrogen peroxide decompose into?

Hydrogen peroxide decomposes into water and oxygen.


Can you purify your water well with hydrogen peroxide?

No, hydrogen peroxide is H2O2, meaning in each molecule there are two hydrogen atoms and two oxygen atoms. Water is H2O, meaning that each molecules has two hydrogen atoms and one oxygen atom. Hydrogen peroxide has different chemical and physical properties from water. It is more acidic, more viscous, and has a higher boiling point. It decomposes easily into water and oxygen and is a strong oxidizer.


What are the active ingredients in hydrogen peroxide?

Hydrogen peroxide is H2O2 and contain hydrogen and oxygen. The active ingredient is the released oxygen.


How many atoms of hydrogen and oxygen are in hydrogen peroxide?

Interesting question. Balanced equation. H2 + O2 >> H2O2 ( let's find moles and limiting reactant ) 10 O2 molecules (1 mole/6.022 X 10 ^23) = 1.66 X 10^-23 moles O2 same for H2, so one to one and reaction is driven by above moles, but use O2 for convenience. actually, as all is one to one, you get back 10 molecules H2O2 anyway 1.66 X 10^-23 X 6.022 X 10^23 = 9.99, or 10 molecules of H2O2

Why is clostridium killed by oxygen?

Clostridium does not have the enzymes (eg. oxidase, catalase) required to deal with the toxic molecules such as oxygen gas or hydrogen peroxide.


Is hydrogen peroxide a reactant?

I think Hydrogen Peroxide is a reactant,because hydrogen and oxygen are reactants so hydrogen peroxide should be a reactant.
