Calculate the frequency of a wave with a wavelength of 5.62 x 1010 m. (first convert m to nm)

f = 0.534×10⁻² Hz

Explanation:

Given data:

Frequency of wave= ?

Wavelength of wave = 5.62×10¹⁰ m

Solution:

Formula:

Speed of wave = wavelength × frequency

Speed of wave = 3×10¹⁷ nm/s

λ  = 5.62×10¹⁰m×10⁹  nm/1 m = 5.62×10¹⁹ nm

Now we will put the values in formula.

3×10¹⁷ nm/s = 5.62×10¹⁹ nm ×  f

f = 3×10¹⁷ nm/s  / 5.62×10¹⁹ nm

f = 0.534×10⁻² s⁻¹   or

f = 0.534×10⁻² Hz

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

the answer would be a
