The scientific method has five basic steps, plus one feedback step: Make an observation. Ask a question. Form a hypothesis, or testable explanation.
False,
The most amazing part of Mendeleev’s periodic table was that he left blank spaces for the elements which were yet to be discovered. He predicted the atomic mass and chemical properties of these yet to be discovered elements.
Here is the correct answer of the given question above. Ferrocene has a higher melting point that acetylferrocene because it takes more energy to overcome the intermolecular forces between atoms. <span>Acetylferrocene melts at 80 degrees and Ferrocene melts at 170. Hope this answer helps.</span>
I am pretty sure that <span>If I were asked to compare matter in solid, liquid, and gaseous states, the statement which would best defined a gas is </span>highest energy, highest molecular motion, and least dense packaging of molecules. I choose this one because it's not sensible to <span>heat CO2 (in case of safety) and in the last option the amount of energy is not satisfying.
Hope it helps!</span>
Partial mass of C, 12*2 = 24
Partial mass of H, 1*5 = 5
Partial mass of N, 14
Partial mass of O, 16
Now, total molar mass would be 24+5+14+16 = 59
mass % of carbon = 24 * 100 / 59 = 40.67%
