I would go with D. All of the above.
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:
<h3>The answer is 2.0 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 4 g
volume = 2 cm³
We have
We have the final answer as
<h3>2.0 g/cm³</h3>
