Yuki888 [10]

<span> The Reactants are Zinc (Zn) and Sulfur (S).
The Product is Zinc Sulfide (ZnS).
All of them are solids.
The combined masses of the reactants must be 14 grams, too. Later in Chemistry you'll learn that's not really true, but it is for now.
Hope This Helps:)

Calculate the average rate of decomposition of NH4NO2 by the reaction 2NH4O5(aq) --> N2(g) H2O(g) at the following time inter

igor_vitrenko [27]

Answer:

$r=-0.033\frac{M}{s}$

Explanation:

Hello!

In this case, since the average rate of reaction is computed as a change given by:

$r=\frac{\Delta [NH_4NO_2 ]}{\Delta t}$

In such a way, given the concentrations at the specified times, we plug them in to obtain:

$r=\frac{(1.48M-4.12M)}{(330s-250s)}\\\\r=-0.033\frac{M}{s}$

Whose negative sign means the concentration decreased due to the decomposition.

Best regards!
