Hey there!
We balance chemical equations because of the law of conservation of mass.
The law of conservation of mass states that matter cannot be created or destroyed, so we must have the same amount of each element on each side of a chemical equation.
The products of a chemical reaction must be equal to the reactants to follow the law of conservation of mass.
Hope this helps!
If the wavelength of the wave is increased to 10 m, the frequency of the wave will be 60 Hz
<h3>Data obtained from the question </h3>
- Wavelength (λ) = 10 m
- Velocity (v) = 600 m/s
<h3>How to determine the frequency of the wave </h3>
The frequency, wavelength and velocity of a wave are related according to the following equation:
Frequency (f) = velocity (v) / wavelength (λ)
f = v / λ
With the above formula, we can obtain the frequency of the wave as follow
f = v / λ
f = 600 / 10
f = 60 Hz
