for the reaction 2H2 + 02 arrow 2H20 jow many moles of water can be produced from 6.0 mol of oxygen

Question

anonymous · Answer

Assuming excess hydrogen, and according to the stoichiometric ratio between oxygen and water (2:1) one mol of O2 will produce 2 mol of water.

So... if you have six moles, how many moles of water will you have?

anonymous · Answer

12

anonymous · Answer

yup, you know why 12 is the answer right?

anonymous · Answer

its double so 6 doubled or 6x2=12

anonymous · Answer

yup, and you know why the ratio is 2:1?

anonymous · Answer

hydrogen is the excess

anonymous · Answer

hydrogen is excess (assumption), so it has nothing to do with the reaction
If you look at the balanced eqn., the coefficient for oxygen is 1, and for water is 2, so that's why you can tell

Btw, please post this in the chem section nxt. time :)
