C.
This is basically the definition of percent composition which is how much mass a element contributes to a specific molecule.
Answer:
an energy level represents the three dimensional space surrounding nucleus where electrons are most likely to be.
Explanation:
Answer:
Joined together to form compounds or rearranged.
Explanation:
Dalton's Theories
-atoms from two or more different elements join together to form compounds in chemical reactions.
-chemical reactions rearrange atoms, but in specific compounds the atoms of different elements always combine in the same way.
Answer: Soundwaves travel as longitudinal or transverse waves depending on the temperature of the medium.
Explanation: i think its C
Answer:
CH3(CH2)8CH3 > CH3CH2CH2CH3 > CH3CH3 (Option f)
Explanation:
Larger and heavier atoms and molecules exhibit stronger dispersion forces than smaller and lighter ones. In a larger atom or molecule, the valence electrons are, on average, farther from the nuclei than in a smaller atom or molecule. They are less tightly held and can more easily form temporary dipoles.
CH3CH3 has a molar mass of 30.07 g/mol
CH3(CH2)8CH3 has a molar mass of 142.28 g/mol
CH3CH2CH2CH3 has a molar mass of 58.12 g/mol
CH3(CH2)8CH3 > CH3CH2CH2CH3 > CH3CH3 (Option f)
