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!

What is the frequency of a wave traveling west with a velocity of 414 meters per second and a wavelength of 1.8 meters? hertz

LuckyWell [14K]

Answer:

230hz

Explanation:

Hello,

To solve this question, we gave to use the relationship between velocity-frequency-wavelength to find the frequency in this question.

V = Fλ

V = velocity or speed of the wave

F = frequency of the wave

λ = wavelength of the wave

Data;

V = 414m/s

λ = 1.8m

f = ?

V = fλ

f = v/λ

f = 414/1.8

f = 230hz

The frequency of the wave is 230hz
