Answer:
The entropy will be 0
Explanation:
Because of the third principle of thermodynamics, the entropy of a pure substance (such as SiC59), with finite density (we have 1 mol in a finite volume), at 0 K is equal to 0.
So, it really dosen't mather the Si atom, if you are analizing it at the absolute zero (0 K).
Answer: 1.80g
Explanation:
Molar Mass of AlCl3 = 27 + (3x35.5)
= 27 + 106.5 = 133.5g/mol
Number of mole of AlCl3 = 0.0135mol
Mass = 0.0135 x 133.5= 1.80g
Answer:
Because Scientists Uses hypothesis and try tests and try proving their points while regular normal people use it to just state a statement
Wavelength= velocity/frequency
wavelength= (3.0 x 10^8m/s) / 7.5 x 10^12 Hz)
you can do the math
I am assuming u that 108 is 10^8 and the 1012 is 10^12
