In the following reaction, which compounds are considered acids ? NH3+H2O <—>NH4+OH

A) NH3 and OH
B) NH3 and H2O
C)H2O and NH4
D) NH4 and NH3

Explanation:

no compound there is considered an acid because this isn't a neutralization reaction ie between an acid and a base ,it didn't even form a salt

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:

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
