sir what i think is that for you to know what is the key of the song then first you have to know what chord is in the song, next step analyze the chord by using the chord diatonic harmonization for example c maj ,a min, d min ,g maj ,c maj this chord progression is in the key of c .For you to play the chords in the particular key you just stack the notes in thirds.
c major scale:c,d,e,f,g,a,b,c
diatonic chord harmonization:
c,e,g=c major
d,f,a=d minor
e,g,b=e minor
f,a,c=f major
g,b,d g major
continue doing for the rest of the notes and do this procedure for other scales and when you have practice doing this regularly you will be able to tell what is the key of a particular song just by analyzing the chord progression.
As for power chords it is not actually a chord because a chord should contain 3 notes or more power chord is made up of only two notes the root and the fifth, for example c5 =c and g
c major scale :c,d,e,f,g,a,b,c
:1,2,3,4,5,6,7,8
so power chord is actually an interval its a perfect fifth it does not have a third .The third of any chord is actually the one that determines whether the chord is a major chord or a minor chord .
for major chords = 1,3,5
minor chords= 1,b3,5
so actually you can use either minor or major scales to solo over a power chord
