Answer: 2.48×10^-17 J
Explanation:
Given the following :
Wavelength = 8nm (8 x 10^-9 m)
Energy(e) of X-ray =?
Energy=[speed of light(c) × planck's constant (h)] ÷ wavelength
Speed of light = 3×10^8m/s
Planck's constant = 6.626×10^-34 Js
Wavelength = 8 x 10^-9 m
Energy = [(3×10^8) * (6.626×10^-34)] / 8 x 10^-9
Energy = [19.878×10^(8-34)] / 8 x 10^-9
Energy = 2.48475 × 10^(-26+9)
Energy = 2.48×10^-17 J
Answer:
<h2>The mosquitoes like when its wet and moist than dry temp.</h2>
If more heat is removed from the reaction the rate of reaction change as below to counter the action
The rate of the <em>forward reaction increase</em> and produces more <em>zinc chloride</em>
<u><em> explanation</em></u>
- <u><em> </em></u>The reaction of zinc and HCl to produce ZnCl and H2 <u><em>is </em></u> exothermic reaction, heat is produced as one product and by removing heat it favor forward reaction
- The position of equilibrium moves to the right since removing heat led to decrease of temperature and more zinc chloride is produced.
