Mg+2HCl=MgCl2+H2W(H2)=0,224л/22,4л=0,01m(Mg)= 0,01•24=0,24 гр

перевидите пожалуйста песню из My Little Pony: Movie
[Verse 1]
So, we wanna stay
But can't find peace while sittin' still
I guess we never will
We're underway
We won't hurry back again
The journey is the end

[Pre-Chorus]
(Oh-oh)
I love this very moment
We're speeding up not slowing
We might know we can't win
But we're dumb enough to try
We're going, there's no maybe
That's why they call us crazy
And we'll say if anybody asks us

[Chorus]
Hey, where you gonna go?
We're off to see the world
We don't need to know, oh
Hey, where you gonna go?
We're off to see the world
We don't need to know

[Verse 2]
We never need to know
Seeking boundaries to break
Let's forget the ones we've made
So we carry on
Don't let good things pass us by
The time we're gone will be the
Best time of our life

[Pre-Chorus]
I love this very moment
We're speeding up not slowing
We might know we can't win
But we're dumb enough to try
We're going, there's no maybe
That's why they call us crazy
And we'll say if anybody asks us

[Chorus]
Hey, where you gonna go?
We're off to see the world
We don't need to know, oh
Hey, where you gonna go?
We're off to see the world
We don't need to know

[Verse 3]
So go tell 'em we won't stop
We know they can't change us
We're gonna go way off the map
To get ourselves back on the track
Go tell 'em we won't stop
We know they can't change us
No need to worry so much
We do whatever we want, oh

[Chorus]
Hey, where you gonna go?
We're off to see the world
We don't need to know, oh
Hey, where you gonna go?
We're off to see the world
We don't need to know

[Outro]
Oh, oh-oh-oh-oh
Oh, oh-oh-oh-oh
Oh, oh-oh-oh-oh
Oh, oh-oh-oh-oh
