there are 2 hydrogen atoms.
it is right answer that is option B.
Hey there!
N₂H₄ + O₂ → NO₂ + H₂O
First, balance N.
Two on the left, one on the right. Add a coefficient of 2 in front of NO₂.
N₂H₄ + O₂ → 2NO₂ + H₂O
Next, balance H.
Four on the left, two on the right. Add a coefficient of 2 in front of H₂O.
N₂H₄ + O₂ → 2NO₂ + 2H₂O
Lastly, balance O.
Two on the left, six on the right. Add a coefficient of 3 in front of O₂.
N₂H₄ + 3O₂ → 2NO₂ + 2H₂O
This is our final balanced equation.
Hope this helps!
Answer:
The correct answer is no.
Explanation:
Tellurium is a chemical element denoted by Te and having atomic number 52. It is mildly toxic, brittle, silver-white, and rare metalloid. The element is chemically related to sulfur and selenium, all three of which are chalcogens.
Oxygen is a chemical element, that is, a substance, which comprises only one kind of atom. Its official chemical symbol is O and exhibits an atomic number 8, this signifies that an atom of oxygen possesses eight protons in its nucleus. In the given question, it is not likely that tellurium would replace for oxygen, as the two elements are highly unlike.
