Question

Please answer.

Thank you.

Answer 1

here you can see that one mole of A react with 2mole of B

hence, 5 mole of A react with 10 mole of B , but here amount of only 8 mole .
so, B is limiting reagent .

hence reaction completed when B is completed ,

we also can say that 2mole of B form 1 mole of C

so, 8 mole of B form 4 mole of C

hence , amount of C = 4 mole
