Answer:
You would gain science knowledge, like if you wanted a science career this is more-than-likely something you would have to learn.
Emission and Absorbance of substances:
-Emission is the process where a substance gives off or emits radiation when it is heated or treated chemically. The level of emission of a substance depends on its spectroscopic composition and temperature.
-Absorption is the process where the electrons of a substance absorb or take up the energy wavelengths incident on them.
Avogadro's number includes all real numbers . A mole concludes of the x as well as the number above which is to the power of how ever many zeros there is
1,200 centilitres is 12 Litres. hope this helped you.
N(Cu)=m(Cu)/M(Cu)
n(H₂O)=4n(Cu)/3
n(H₂O)=4m(Cu)/{3M(Cu)}
n(H₂O)=4*98.6g/{3*63.5g/mol}=2.0703≈2.1 mol
n(H₂O)=2.1 mol
