Question

10g of hydrogen and 64g of oxygen were filled in a steel vessel and exploded. Amount of water produced in this reaction will be......?(a)2 mol (b)3 mol (c)4 mol (d)1 mol

Answer 1

it is (c) 4 moles

2H2+O2------->2H2O

So there are 5 moles of H2 and 2 moles of O2
Hence, O2 is the limiting reagent here
now every 1 mole of O2 gives 2 moles of H2O,
so every 2 moles of O2 gives 4 moles of H2O.

Answer 2

Answer:look,

2h2O + O2 =2h2O

Here , h20 contain 2 mole and 02 contains 1 mol and 2h20 contains 2 mole

Therefore ,

Ratio will be

2:1:2

And also 02 is limiting reagent

Therfore

1/2 = 2/x

2×2 = 4

Here is the answer....
