    Yeah
    You are my fire
    The one desire
    Believe when I say
    I want it that way
    But we are two worlds apart
    Can't reach to your heart
    When you say
    That I want it that way
    Tell me why
    Ain't nothin' but a heartache
    Tell me why
    Ain't nothin' but a mistake
    Tell me why
    I never want to hear you say
    I want it that way
    Am I, your fire?
    Your one, desire
    Yes I know, it's too late
    But I want it that way
    Tell me why
    Ain't nothin' but a heartache
    Tell me why
    Ain't nothin' but a mistake
    Tell me why,
    I never want to hear you say
    I want it that way
    Now I can see that we've fallen apart
    From the way that it used to be, yeah
    No matter the distance
    I want you to know
    That deep down inside of me
    You are my fire
    The one desire
    You are (you are, you are, you are)
    Don't want to hear you say
    Ain't nothin' but a heartache
    Ain't nothin' but a mistake
    (Don't want to hear you say)
    I never want to hear you say
    I want it that way
    Tell me why
    Ain't nothin' but a heartache
    Tell me why
    Ain't nothin' but a mistake
    Tell me why
    I never want to hear you say
    I want it that way
    Tell me why
    Ain't nothin' but a heartache
    Ain't nothin' but a mistake
    Tell me why
    I never want to hear you say
    (Never want to hear you say it)
    I want it that way
    'Cause I want it that way

    Hercules and his gifts
    Spider-Man's control
    And Batman with his fists
    And clearly I don't see myself upon that list
    But she said, where'd you wanna go?
    How much you wanna risk?
    I'm not lookin' for somebody
    With some superhuman gifts
    Some superhero
    Some fairy-tale bliss
    Just something I can turn to
    Somebody I can kiss

    The testaments they told
    The moon and its eclipse
    And Superman unrolls
    A suit before he lifts

    There is nobody better than you
    It took me a while 'til I knew
    But you knew from the start it was us, didn't you?
    It just took me a while 'til I knew
    Now I lay as I study a blank wall
    Would you spare me your voice if I call?
    'Cause you waited and watered my heart 'til it grew
    You just grew a little smarter, too
    So I don't blame you
    If you want to bury me in your memory
    I'm not the girl I ought to be, but
    Maybe when you tell your friends
    You can tell them what you saw in me
    And not how I turned out to be
    There is some kind of burning inside me
    It's kept me from falling apart
    And I'm sure that you've seen what it's done to my heart
    But it's kept me from falling apart
    Now here I lay as I wonder about you
    Would you just tell me what I'm meant to do?
    'Cause I've waited and watered my heart 'til it grew
    You can see how it's blossomed for you
    And I don't blame you
    If you want to bury me in your memory
    I'm not the girl I ought to be, but
    Maybe when you tell your friends
    You can tell them what you saw in me
    And not the way I am
    And I don't mean to make your heart blue
    But could we be what we're meant to be?
    I'm just about to beg you, please
    And then, when you tell your friends
    You can tell them what you saw in me
    And not the way I used to be
    'Cause there is nobody better than you

    Brothers of the mine rejoice!
    Swing, swing, swing with me
    Raise your pick and raise your voice!
    Sing, sing, sing with me
    Down and down into the deep,
    Who knows what we'll find beneath?
    Diamonds, rubies, gold and more
    Hidden in the mountain store.Born underground, suckled from a teat of stone.
    Raised in the dark, the safety of our mountain home.
    Skin made of iron, steel in our bones,
    To dig and dig makes us free!
    Come on brothers sing with me!

      Diggy diggy hole, diggy diggy hole
      I am a dwarf and I'm digging a hole
      Diggy diggy hole, digging a hole!The sunlight will not reach this low
      Deep, deep in the mine
      Never seen the blue moon glow
      Dwarves won't fly so high
      Fill a glass and down some mead!
      Stuff your bellies at the feast!
      Stumble home and fall asleep
      Dreaming in our mountain keepBorn underground, grown inside a rocky womb
      The earth is our cradle; the mountain shall become our tomb
      Face us on the battlefield; you will meet your doom
      We do not fear what lies beneath
      We can never dig too deep

    Somebody once told me the world is gonna roll me
    I ain't the sharpest tool in the shed
    She was looking kind of dumb with her finger and her thumb
    In the shape of an "L" on her forehead
    Well, the years start coming and they don't stop coming
    Fed to the rules and I hit the ground running
    Didn't make sense not to live for fun
    Your brain gets smart but your head gets dumb
    So much to do, so much to see
    So what's wrong with taking the backstreets?
    You'll never know if you don't go
    You'll never shine if you don't glow
    Hey now, you're an all star
    Get your game on, go play
    Hey now, you're a rock star
    Get the show on, get paid
    And all that glitters is gold
    Only shooting stars break the mold
    It's a cool place, and they say it gets colder
    You're bundled up now, wait 'til you get older
    But the meteor men beg to differ
    Judging by the hole in the satellite picture
    The ice we skate is getting pretty thin
    The water's getting warm so you might as well swim
    My world's on fire, how 'bout yours?
    That's the way I like it and I'll never get bored
    Hey now, you're an all star
    Get your game on, go play
    Hey now, you're a rock star
    Get the show on, get paid
    All that glitters is gold
    Only shooting stars break the mold
    Somebody once asked
    Could I spare some change for gas?
    "I need to get myself away from this place"
    I said, "Yep, what a concept
    I could use a little fuel myself
    And we could all use a little change"
    Well, the years start coming and they don't stop coming
    Fed to the rules and I hit the ground running
    Didn't make sense not to live for fun
    Your brain gets smart but your head gets dumb
    So much to do, so much to see
    So what's wrong with taking the backstreets?
    You'll never know if you don't go (go!)
    You'll never shine if you don't glow
    Hey now, you're an all star
    Get your game on, go play
    Hey now, you're a rock star
    Get the show on, get paid
    And all that glitters is gold
    Only shooting stars break the mold
    Hey now
    Hey now
    Hey, hey, hey now
    Hey now
    Hey now, you're an all star
    Hey now, you're an all star
    Hey now, you're an all star
    Only shooting stars break the mould

    Hello darkness, my old friend
    I've come to talk with you again
    Because a vision softly creeping
    Left its seeds while I was sleeping
    And the vision that was planted in my brain
    Still remains
    Within the sound of silence
    In restless dreams I walked alone
    Narrow streets of cobblestone
    'Neath the halo of a street lamp
    I turned my collar to the cold and damp
    When my eyes were stabbed by the flash of a neon light
    That split the night
    And touched the sound of silence
    And in the naked light, I saw
    Ten thousand people, maybe more
    People talking without speaking
    People hearing without listening
    People writing songs that voices never share
    And no one dared
    Disturb the sound of silence
    "Fools", said I, "You do not know
    Silence like a cancer grows
    Hear my words that I might teach you
    Take my arms that I might reach you"
    But my words, like silent raindrops fell
    And echoed
    In the wells of silence
    And the people bowed and prayed
    To the neon god they made
    And the sign flashed out its warning
    In the words that it was forming
    And the sign said, "The words of the prophets are written on the subway walls
    And tenement halls"
    And whispered in the sound of silence

      That's why it turns the red litmus paper blue, and why the paper must be damp: ammonia reacts with water and turns into ammonia water which is basic.

    Call poison control if you’re bit by a spider
    But check that it’s covered by your health care provider!
    Are you hungry? Well quit your whining
    The new downtown has five-star dining
    You lack coal mines and you wanna see ‘em
    Well check it out yo, the Anthracite Museum
    The dope thing to do, that’s several and countin’
    The illest place to go is Montage Mountain
    Plenty of space in the parking lot
    But the little cars go in the compact spot!

      That’s why you test with NaOH and NH3 and write down your observations for one sample. No sample will have the same results for both reagents, so you can compare and identify the cation afterwards
