The overall balanced reaction equation is;

4Zn(s) + 10H^+(aq) + NO3^-(aq) -----> 4Zn^2+(aq) + NH4^+(aq) + 3H2O(l)

<h3>What is the balanced reaction equation?</h3>

The redox reaction equation is said to be balanced when the number of electron gained is equal to the number of electrons lost.

Now;

1. Reduction and oxidation half-reactions

Zn(s) -----> Zn^2+(aq) + 2e

And

NO3^-(aq) ---->NH4^+(aq) + 3H2O(l)

2. Using the H2O and H+ to balance O and H;

4Zn(s) + 10H^+(aq) + NO3^-(aq) -----> 4Zn^2+(aq) + NH4^+(aq) + 3H2O(l)

3. Balancing the electrons lost and gained; 4Zn(s) + 10H^+(aq) + NO3^-(aq) + 8e -----> 4Zn^2+(aq) + NH4^+(aq) + 3H2O(l) + 8e

4. The overall balanced reaction equation is;

4Zn(s) + 10H^+(aq) + NO3^-(aq) -----> 4Zn^2+(aq) + NH4^+(aq) + 3H2O(l)

Given the speed of light (3.00 × 108 m/s) and a wavelength 5.9 × 10-7 m, what is the frequency?
Cerrena [4.2K]
Wavelength x Frequency = Speed

So, 5.9 x 10^-7 x F = 3 x 10^8

Rearranging the equation, we get:
F = (3 x 10^8)/(5.9 x 10^-7) = 5.08 x 10^14 Hz

Hope I helped!! xx
