be required to react completely with 4g of hydrogen :
(A) 10 gm
(B) 48 gm
(C) 32 gm
(D) 64 gm
please tell with explanation i will mark the first one brilliantest ​

Answer 1

hope it helps uh

Explanation:

Thus, 24 g of oxygen gas would be required to react completely with 3 g of hydrogen gas.

Answer 2

Explanation:

1 g of hydrogen reacts with = 8 g of oxygen

∴ 3 g of hydrogen reacts with = 8 × 3 = 24 g of oxygen

Thus, 24 g of oxygen gas would be required to react completely with 3 g of hydrogen gas.
