Question

If you were to combine 80.0 g of oxygen with some hydrogen to form water, how much hydrogen would you need to completely use up all of the oxygen?

science chemistry

Answer 1

Answer #1

first balance the reaction and then proceed

.5 mole of oxygen combine with 1 mole of hydrogen,

So 2.5 mole of oxygen combine with 5 moles of hydrogen.

Hence 5moles hydrogen = 10gm
