Question

6g H2 reacts with 8 g oxygen to give water. After the completion of reaction, what is the limiting reagent?(with explanation)
No plagiarism or absurd answers please. First right answer will be marked brainliest

Answer 1

Answer:

limiting reagent is H2

Answer 2

IF THIS HELPS PLEASE MARK ME WITH THE BRAINLIEST

2H2 +O2=====> 2H20

6 g of H2+ 8 g of O2

according to the ratio of hydrogen to oxygen 2:1 that means,

6 g of hydrogen will reacts with 3 g of oxygen  to give = ?

the whole 6 g of hydrogen has been used up  with a remaining 5g of oxygen

AT THE END OF REACTION

6g of H2 +3 g of O2 WILL GIVE  =  6 g of water(steam)

WITH A REMAINING 5 g of oxygen

so the limiting reagent is the substance that is totally consumed when the chemical reaction is completed.  so the reaction cannot continue without it.

LIMITING REAGENT IS HYDROGEN GAS(H2)
