(a) What is the frequency of light of 405 nm wavelength?
1 answer:
f = 7.4 x 10²⁰s⁻¹
Explanation:
Given parameters:
wavelength of light = 405 x 10⁻⁹m or 405nm
Unknown:
Frequency of light = ?
Solution:
We can solve this problem using the wave equation:
V = f∧
where V is the velocity of light = 3 x 10⁸m/s
f is the unknown frequency
∧ is the wavelength of light
making f the subject:
f = =
}{405 x 10
}[/tex]
f = 7.4 x 10²⁰s⁻¹

Answer: 8.59 L of oxygen gas are needed to produce 100 kJ of energy at STP
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
Standard condition of temperature (STP) is 273 K and atmospheric pressure is 1 atmosphere respectively.
1 mole of every gas occupy volume at STP = 22.4 L
The balanced chemical reaction is:
3909.9 kJ of of energy is produced by =
100 kJ of oxygen gas are needed to produce =
