3.833 kJ of heat is required to convert a 36.8 g sample of ethyl alcohol from the solid to liquid phase. What is the heat of
fusion of ethyl alcohol in J/g?

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

a corroding iron, if that's one of your choices

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
