Do chemical equations with no reaction still have to be balanced

Chemistry
1 answer:
dangina [55]3 years ago
5 0

Answer:

The same number of atoms of each element must appear on both sides of a chemical equation. However, simply writing down the chemical formulas of reactants and products does not always result in equal numbers of atoms. You have to balance the equation to make the number of atoms equal on each side of an equation.

What is the wavelength of a photon that has a frequency of 4.82 x 1014 hz
rjkz [21]

The wavelength of a photon is 622nm and it is a red light.

<h3>What is Wavelength?</h3>

The length of a waveform signal that is propagating in space or over a wire is measured by the separation between identical points (adjacent crests) in the adjacent cycles. This length is typically specified in meters (m), centimetres (cm), or millimetres (mm) in wireless systems (mm).

<h3>What is Photon?</h3>

A discrete bundle (or quantum) of electromagnetic (or light) energy is referred to as a photon. Photons move at the speed of light (3 108 m/s) because they have no mass.

<h3>What are the calculations?</h3>

λ = v/f

where, f = frequency = 4.82 × 10^{14} Hz

v = speed of light = 3 × 10 ^{8} m/s

λ = 3 × 10^{8} / 4.82 × 10^{14}

λ = 6.22 × 10^{-7}

λ = 622 nm.

Hence, the wavelength of a photon is 622nm and it is red light.
