Question

question 12 (1 point) what is the minimum number of moles of hno3 needed to produce 8 moles of n2o5? 2 16 12 4 8

Explanation:

Step1: Write the balanced chemical equation

$4HNO_3
ightarrow 2N_2O_5 + 2H_2O$
From the equation, the mole - ratio of $HNO_3$ to $N_2O_5$ is $4:2$ or $2:1$.

Step2: Set up the proportion

Let $x$ be the moles of $HNO_3$. We know the mole - ratio $\frac{x}{8}=\frac{2}{1}$.

Step3: Solve for $x$

$x = 16$ moles.

Answer:

16
