GIVE IT FASTT! I WILL MARK IT AS BRAINLIEST!!!

Answer 1

Answer:

D. Both B and C

Explanation:

To make water there is the requirement of 4 moles of hydrogen and 1 mole of dioxygen to form 2 moles of water but in option B there are only two hydrogen and 1 mole of dioxygen to form 1 mole of water which is wrong also in option C there is requirement of 4 hydrogen to make 2 moles of water and it is not fulfilled, hence option B and C both are incorrect and are not obeying conservation of mass. that's why option d is the correct.

I hope you are clear if not just comment me and mark me as the brainliest.
