Answer:

When you fill in 2 reactants, you will have 6 N atoms but on the side of the product there are only 2 N atoms, so the equation cannot be balanced and for the equation to be equal, you need to fill 3 into the part N2 to have 6 N atoms

Explanation:

2NaN3 => 2Na + N2

There are 6 nitrogen atoms on the left side but only 2 nitrogen atoms on the right side.

The equation would be balanced if there was a "3" infront of N2.

Given that the frequency of a wave is 9.12x10^-12 Hz, what must be the
polet [3.4K]

Answer:

The wavelength of wave is 0.33 ×10²⁰ m.

Explanation:

Given data:

Frequency of wave = 9.12×10⁻¹² Hz

Wavelength of wave = ?

Solution:

Formula:

Speed of light = wavelength × frequency

c = λ × f

λ = c/f

This formula shows that both are inversely related to each other.

The speed of light is 3×10⁸ m/s

Frequency is taken in Hz.

It is the number of oscillations, wave of light make in one second.

Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.

Now we will put the values in formula.

λ = 3×10⁸ m/s  / 9.12×10⁻¹² Hz

Hz = s⁻¹

λ = 0.33 ×10²⁰ m  

The wavelength of radiation is 0.33 ×10²⁰ m  .
