Answer: the percentage composition of Hydrogen is 18%
Explanation:Please see attachment for explanation
Collect the salt water and put it in something where it can boil under fire or any other heat source capable to bring the water to boiling temperature. You can consume the collected water safely , but wait for its temperature to fall, except if you need it to be hot.
Answer:
λ = 1.62×10¹¹ nm
Explanation:
Wavelength of radiation = ?
Frequency of radiation = 1.85 MHz (1.85 ×10⁶ Hz)
Solution:
Formula:
Speed of radiation = frequency × wavelength
c = speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 1.85 ×10⁶ Hz × λ
λ = 3×10⁸ m/s / 1.85 ×10⁶ s⁻¹
λ = 1.62×10² m
In nm:
1 m = 10⁺⁹ nm
λ = 1.62×10¹¹ nm
The rate of effusion of H₂ : 7.2 x 10⁻² m/s
<h3>Further explanation </h3>
Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or
the effusion rates of two gases = the square root of the inverse of their molar masses:
or
MW₁ O₂ = 32 g/mol
MW₂ H₂ = 2 g/mol
