Answer:
Wavelength = 9.4×10⁹ m
Explanation:
Given data:
Frequency of radiation = 3.2×10⁻² Hz
Wavelength of radiation = ?
Solution:
Formula:
Speed of light = frequency ×wavelength
Speed of light = 3×10⁸m/s
Now we will put the values in formula.
3×10⁸m/s = 3.2×10⁻² Hz × wavelength
Wavelength = 3×10⁸m/s /3.2×10⁻² s⁻¹
Wavelength = 0.94×10¹⁰ m
Wavelength = 9.4×10⁹ m
Answer:
How about this?
Explanation:
(1) Halogenation of an alkane
Reaction with Br₂ in the presence of UV light to give bromocyclopentane.
(2) Dehydrohalogenation
Reaction with hot alcoholic KOH to give cyclopentene.
(3) Allylic bromination
Reaction with N-bromosuccinimide and a drop of HBr(aq) gives
3-bromocyclopentene.
Im not sure but I did this a long time ago I think its 5.00 mols
First let us compute for the number of moles of butane
(molar mass = 58.12 g/mol)
number of moles = 145 g / (58.12 g/mol) = 2.49 mol
<span>We use the ideal
gas equation to calculate the volume:</span>
<span> V = n R T / P</span>
V = 2.49 mol * 62.36367 L torr / mol K * 308.15 K / 745
torr
<span>V = 64.35 L</span>
