Lung cancer does not effect the environment. Lung cancer is caused by uncontrolled cell growth of tissue in the lungs inside the body therefore not effecting the environment.
PV=nRT<=> P=nRT/V=2,40*R*(273+97)/45 atm.
Calculate it. R is a number that is given, find it and use your math to solve.
Answer: Yes the absorb in the visible range.
Explanation:
The relationship between wavelength and energy of the wave follows the equation:
where,
= energy of the wave = 182 kJ/mol = 182000 J/mol
N = avogadro's number = 
h = plank constant = 
c = speed of light = 
= wavelength of the wave = ?
Putting all the values:
The wavelength range for visible rays is 400 nm to 750 nm, thus the complex absorb in the visible range.
Answer:
in all green plants and most algae
Answer:
Isotopes are basically atoms of an element that have an unequal number of neutrons and protons. Of course the proton number remains the same, but the neutron number either decreases or increases, which leads to an overall change in mass. However, no chemical properties of the atom/element are changed as the electrons are the same number and do not react. In regards to Helium 4, the original number of neutrons in Helium is 2, and protons 2 as well. We see an equal number of neutrons and protons, hence an unchanged mass, and the element is <em>not</em> an isotope.
