Since hydrogen bonding is a stronger intermolecular force than van der Waals forces, more energy is required to separate the molecules of ethanol than the molecules of ethane. Thus ethanol has a higher melting point than ethane.
Answer:
5
Explanation:
mass number=no of protons +no of neutron
mass number-atomic number=no of neutron
12-7=5
Answer:
8
I believe 2 moles are produced :/
Answer: they are lung, lung tissues, and lung cells.
Explanation:
number of mole s of H
2
= 0.25 moles
number of molecules = moles * Avogadro’s Number
number of molecules = 0.25×(6.022×10
23
)
number of molecules = 1.505×10
23
single molecule of hydrogen contains two H-atoms. So,
number of atoms = 2×(1.505×10
23
) = 3.01×10
