A chemistry question!

 

 

now...this is one chemistry question i have no idea about so pls ...pls if you know the answer ...explain it to me in full detail....i have seriously not a bit of idea about it....please explain me in full detail.....i'd really appreciate it....thank you!

 

 

Hydrogen and oxygen combine in a ratio 1:8 by mass.Predict the ratio in terms of number of particles.

Mmm, I am not into chemistry but

2 Hydrogen +1 oxygen = water :)

 

I am not sure if that answers your question and i think you want someone to explain it better anywasy.  It is a pity that Sevenup is not about :)

Perhaps this answers your answer...

 

There's 1 hydrogen per 8 oxygen. 

 

I hope that helps!!!

Hydrogen and oxygen combine in a ratio 1:8 by mass.Predict the ratio in terms of number of particles

 

Since 1 mole of H = 1 gram=6.022 X 10^23 atoms, and since 1 mole of O=~16 grams=6.022 X 10^23 atoms, therefore a ratio of 1:8 by mass=6.022 X 10^23:[6.022 X 10^23/2=3.011 X 10^23]; OR,

1:8 by mass =6.022E23:3.011E23 in terms of number of particles.

Hydrogen and oxygen combine to form water which is H2O.   That is there are two atoms of hydrogen for every one of oxygen.

 

The atomic mass of hydrogen is 1; that of oxygen is 16.   Hence in a water molecule the total mass of hydrogen to that of oxygen is 2:16 which is the same as 1:8

2H2 + O2 = 2 H20

The ratio of PARTICLES is  2:1     'Two'  H2 molecules to 'ONE' O2 molecule    Note: MOLECULE, not ATOMS.

 

 

 

(Hydrogen and Oxygen can also combine to Hydrogen peroxide  h2o2....   fyi)
