58.44g/mol*1/6.93g= 8.43moles of NaCL
I think the correct answer would be A. When a polonium atom with 84 protons, 124 neutrons, and 84 electrons undergoes alpha decay, a lead atom would be produced with 82 protons, 122 neutrons, and 84 electrons together with an alpha particle having two protons and two neutrons.
Answer:
The basic principle of this type of distillation is that different liquids boil and evaporate at different temperatures. So when the mixture is heated, the substance with a lower boiling point starts to boil first and convert into vapors. Let consider a liquid-liquid mixture of A and B where A is more volatile than B this mixture can be separated by the following process:
Explanation
B is the answer I

In a macroscopic object, each particles wave is being absorbed and combined with the waves of the other particles to create one wave for the entire object. Since this object is able to be seen, the wave function immediately collapses.
Anytime you possess anykind of information about the world around us, some wave, somewhere function collapses.
In short, if we can see the object, then it has no wave function.
