<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
<h3><u>Answer and explanation</u>;</h3>
The balanced chemical equation will be;
NaHCO3 + CH3COOH = CH3COONa + H2O + CO2
After balancing the chemical equation the number of atoms of each element is the same on the reactants and on the products side.
Sodium atoms - 1
Hydrogen atoms - 5
Carbon atoms - 3
Oxygen atoms - 5
The symbol for carbon is simply C

The only nonmetal
that is liquid at room temperature is the element Br or Bromine. When we say at
room temperature, it means at zero degrees Celsius and at one atmospheric
pressure. The metal that is liquid at room temperature is the element Hg or
mercury.
