Question

What is the problem with the chemical equation shown below?

H2 + O2 → H2O

-There is a missing hydrogen in the reactants.
-There is a missing oxygen in the product.
-There is an additional oxygen in the product.
-There is an additional hydrogen in the reactants.

(its multiple choice btw please help)

Answer 1

Answer:

2nd option is the right answerr

Answer 2

Answer:

THE ANS IS SECOND OPTION.THIS IS CORRECT EQUATION=2H2+O2=2H2O

Explanation:

H2+O2=H2O

HYDROGEN=ON L. H. S 2hydrogens

ON R. H. S 2hydrogens

OXYGEN= ON L. H. S 2oxygens

ON R. H. S 1oxygen

we should balance

multiple 2 on R. H. S and multiple 2 on L. H. S on hydrogen ATOM

2×H2+O2=2×H2O

AFTER BALANCING THE EQUATION IS 2H2O+O2=2H2O

NOW, HYDROGEN ATOM=ON L. H. S 2×2=4

ON R. H. S HYDROGEN ATOM=2×2=4

OXYGEN ATOM=ON L. H. S=2

ON R. H. S=2×1=2
