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
Uhhhhhhhhhhhhhh wut, can you rewrite it?
the reaction is
2NO(g) + 2H2(g) <—> N2(g) + 2H2O (g)
Kc = [N2] [ H2O]^2 / [NO]^2 [ H2]^2
Given
moles of NO = 0.124 therefore [NO] = moles /volume = 0.124 /2 = 0.062
moles of H2 = 0.0240 , therefore [H2] = moles / volume = 0.0240 / 2 = 0.012
moles of N2 = 0.0380 , therefore [N2] = moles / volume = 0.0380 / 2 = 0.019
moles of H2O = 0.0276 , therefore [H2O] = moles / volume = 0.0276 / 2 = 0.0138
Kc = (0.019) ( 0.0138)^2 / (0.062)^2 ( 0.012)^2 = 6.54
Answer:
Osmosis is how plants are able to absorb water from soil. The roots of the plant have a higher solute concentration than the surrounding soil, so water flows into the roots. In plants, guard cells are also affected by osmosis. These are cells on the underside of leaves that open and close to allow gas exchange.
Hope this helps.
