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​

Answer 1

First we see reaction by which form water

2H2+ O2--->2H2O

here we see 2mole hydrogen react with 1mole Oxygen form two mole water

we have

10gm hydrogen =5mole hydrogen

64gm Oxygen =2mol mole oxygen

we know according to above reaction

4gm hydrogen react with 32gm oxygen

so,

10gm hydrogen react with 80gm oxygen

but we have given amount of oxygen only 64 gm it means Oxygen is here limiting reagent .

now

all oxygen reat then 8gm hydrogen react and form 4mole of water .
