If 2.00 moles of H₂ and 1.55 moles of O₂ react how many moles of H₂O can be produced in the reaction below?
jekas [21]

Answer:

2 mol H₂O

Explanation:

With the reaction,

  • 2H₂(g) + O₂(g) → 2 H₂O(g)

1.55 moles of O₂ would react completely with ( 2*1.55 ) 3.1 moles of H₂. There are not as many moles of H₂, thus H₂ is the limiting reactant.

Now we <u>calculate the moles of H₂O produced</u>, <em>starting from the moles of limiting reactant</em>:

  • 2.00 mol H₂  * \frac{2molH_2O}{2mol H_2} = 2 mol H₂O

Balance the equation for the reaction of benzene and hydrogen to form cyclohexane.. C6H6 + H2 → C6H12.
Vedmedyk [2.9K]
Here is a universal law to balance chemical equations :
All chemical equations must be balanced because of the law of conservation of mass.
It states that "matter cannot be created or destroyed."
So, the number of atoms that you start with at the beginning of the reaction must equal the number of atoms that you end up with.
 keeping this law in our mind,lets balance the<span> equation for the reaction of benzene and hydrogen to form cyclohexane.
</span><span>C 6 H 6 + H 2 → C 6 H 12.
Here is the balance chemical equation.
</span><span>2 C 6 H 6 + 6 H 2 → 2 C 6 H 12.</span>
