The given question is incomplete. The complete question is :
It takes 151 kJ/mol to break an iodine-iodine single bond. Calculate the maximum wavelength of light for which an iodine-iodine single bond could be broken by absorbing a single photon. Be sure your answer has the correct number of significant digits.
Answer: 793 nm
Explanation:
The relation between energy and wavelength of light is given by Planck's equation, which is:
where,
E = energy of the light = 151 kJ= 151000 J (1kJ=1000J)
N= moles = 1 =
h = Planck's constant =
c = speed of light =
= wavelength of light = ?
Putting in the values:
Thus the maximum wavelength of light for which an iodine-iodine single bond could be broken by absorbing a single photon is 793 nm
Answer:
A
Explanation:
Because total energy is always constant, it only changes form but energy is never destroyed nor created. This is 1st law of thermodynamics which is basically principle of conservation of energy.
Hope this helps!
Answer:
CaCO3+2HCl=CaCl2+H2O+CO2 this is the balanced reaction occur between calcium carbonate and HCl to minimize the hyperacidity.
Explanation:
CaCO3 reacts with hydrochloric acid produced by oxytonic cells of the stomach to generate calcium chloride (CaCl2) and water(H2O) along with the release of carbon dioxide(CO2) gas.
This reaction helps to minimize hyperacidity.
