How many hydrogen peroxide molecules are expected if 100 oxygen molecules react with 10 hydrogen molecules?

Answer 1

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.

Answer 2

If 100 oxygen molecules react with 10 hydrogen molecules to produce hydrogen peroxide, then 10 hydrogen peroxide molecules are expected, because each hydrogen peroxide molecule requires one oxygen and one hydrogen molecule for its formation.

Answer 3

(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!

Answer 4

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.

Answer 5

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