Answer:
- The limiting reagent is N2O4
- 14,09g
Explanation:
- First, we adjust the reaction.
+
⇄
- Second, we assume that the participating moles are equal to the stoichiometric ratios because we do not know the amounts of the reagents.
We can determinate what is the limiting reagent comparing of product amounts which can be formed from each reactant.
Using to form
Using to form
The limiting reagent is N2O4, because can produce only 0, 783 mol of H2O.
This is the minimum measure can be formed of each product.
∴
4.3 x 10⁻⁸dm⁻²
Explanation:
Problem:
To solve this problem, we have apply the right rule of indices operation.
If we have an indices in the form;
= (
)
Solving this problem:
= x 10
)
= 0.43 x 10⁻⁷
= 4.3 x 10⁻¹ x 10⁻⁷
= 4.3 x 10⁻⁸
for the units:
=
The solution is: 4.3 x 10⁻⁸dm⁻²
