The order of increasing wavelength (and decreasing energy) of the given radiations is:
Gamma Rays > X-Rays > Visible Light > Radio waves
X-rays due to the short wavelength and higher energies have the ability to penetrate through soft tissues like the skin or get absorbed by hard tissues like the bones. Thus, when the human anatomy is exposed to X-rays, bones appear white whereas the skin/tissues appear gray.
Ans: A) X-rays are used by doctors to view skeletal structures
Answer:
Fewer bubbles will be produced because of fewer collisions of reactant molecules
Explanation:
As the solid dissolves into the solution after the liquid has been vigorously bubbled, if the temperature of the liquid is reduced a little, what will happen is that fewer bubbles will be produced as a result of lesser amount of collisions occurring between the reactant molecules
Answer:
<h3>» a. Magnesium</h3>
Explanation:
<h3>• Magnesium is least reactive and </h3>
<h3>• Magnesium has atomic number 12. Its electronic configuration is 2,8,2 . Thus, it has </h3><h3>2 valence electrons.</h3>
A gas can be treated as ideal gas when it is at higher temperatures or low pressures relative to its critical temperature and pressure. Because, at high temperatures and low pressures, the density of gas decreases and at low densities real gases behave as ideal gases.
