It has 78 neutrons in a cesium
Answer:
4
Explanation:
Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by .
Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.
Avogadro constant:-
Hence,
Mass of = 131.293+ n18.998 g
So,
molecules have a mass of 131.293+ n18.998 g
Also,
molecules have a mass of g
So,
molecules have a mass of g
Also, given mass = 0.172 g
Thus,
<u>Thus, value of n is 4.</u>
Answer:
Physical properties are controlled by the mineral's chemical composition and atomic structure, this combination is distinct in each mineral.
Explanation:
Hello,
Since the physical properties depend on the mineral's chemical composition and the atomic structure (molecular arrangement), we can distinguish different minerals by measuring out hardness, cleavage and other properties in order to analyze their behavior under several conditions and subsequently use them in a particular application.
Best regards.
Answer:
c.
Explanation:
it is c.-1 because oxidation number of cl is-1
The U-235 fission will produce krypton-92 and barium-141. And this process will also release huge amount energy. And U-235 also go through α decay model.
