Answer 1

No, you can't combine them that way. You'll have to write a mixin that is invoked by your extend class and anything inside of a media query.

@mixin my-extend {
    background: yellow;
}

%my-extend {
    @include my-extend;
}

.foo {
    @extend %my-extend;
}

.bar {
    @extend %my-extend;
}

.baz {
    @media (min-width: 30em) {
        @include my-extend;
    }
}

Output:

.foo, .bar {
  background: yellow;
}

@media (min-width: 30em) {
  .baz {
    background: yellow;
  }
}
