<h3>
Answer:</h3>
4.73 × 10^4 m
<h3>
Explanation:</h3>
From the question;
Frequency of the photon = 634 × 10^12 Hz
We are required to calculate the wavelength of the photon.
We need to know the relationship between wavelength and frequency of a wave.
The relationship between f and λ is given by;
c = fλ
Where c, is the speed of light, 2.998 × 10^8 m/s
Therefore, to get the wavelength we rearrange the formula such that;
λ = c ÷ f
= 2.998 × 10^8 m/s ÷ 634 × 10^12 Hz
= 4.73 × 10^-5 m
But we require wavelength in nm
1 M = 10^9 nm
Therefore;
Wavelength = 4.73 × 10^-5 m × 10^9 nm/m
= 4.73 × 10^4 m
Hence, the photon's wavelength is 4.73 × 10^4 m

Answer:
The answer to your question is SO₂ + 3H₂ ⇒ H₂S + 2H₂O
Explanation:
Reaction
SO₂ + H₂ ⇒ H₂S + H₂O
Reactants Elements Products
1 Sulfur 1
2 Hydrogen 4
2 Oxygen 1
This reaction is unbalanced so we need to balance it.
SO₂ + 3H₂ ⇒ H₂S + 2H₂O
Reactants Elements Products
1 Sulfur 1
6 Hydrogen 6
2 Oxygen 2
Now, the reaction is balanced
