Question

Jim drops an iron magnet during a chemistry lab experiment. She finds that it is no longer magnetic. What has happened in terms of its properties?

a. A chemical change occurred that changed the iron in the magnet into nickel.

b. A physical change occurred that changed the iron in the magnet into nickel.

c. A chemical change occurred in which the iron remained iron, but lost one of its chemical properties.

d. A physical change occurred in which the iron remained iron, but lost one of its physical properties.
*** do not understand AT ALL. :( Please explain to

Answer 1

thanks for coming!! :) just wondering are you guys like really good at chem or something?

Answer 2

any options you have already ruled out?

Answer 3

i think it is not a chemical change... am i right?

Answer 4

because maybe the magnet fell out or something???

Answer 5

am i right that it is NOT a chemical change?

Answer 6

you are right there ...go on

Answer 7

so the only answer choices left are B and D yah??

Answer 8

i kinda think it is d. A physical change occurred in which the iron remained iron, but lost one of its physical properties. cuz it's physical property being its magnetism right??

Answer 9

and i don't think it changed into nickel.... am i on the right track? =)

Answer 10

Yes ... you are absolutely right

Answer 11

so the answer is D then?? :)

Answer 12

iron can't just decide to turn into another element because you drop it...

yes it is D.

Answer 13

yay!! thanks!!! :)

Answer 14

if the iron turned to nickel that would be a nuclear reaction ,


a chemical reaction involves two chemical say the iron and the polyvinylchloride floor, or if the iron was hot enough from then bang to turn to rust , due to reacting with the oxygen in the air then it would be a chemical reaction

Answer 15

but the bang could not be of that magnitude

Answer 16

since iron acts as a magnet if its atoms are neatly aligned... dropping the magnet can change the alignment of some of the atoms...

Answer 17

weakening its magnetism

Answer 18

i understand this soooo much now!! thanks for all your help @UnkleRhaukus and @PaxPolaris !!! I appreciate it soooooooooo much!! :) I would give y'all a cookie if i could.. but i can't :( http://www.google.com/imgres?q=cookie&um=1&hl=en&sa=N&biw=1271&bih=680&tbm=isch&tbnid=6kcV1kYsM3WLyM:&imgrefurl=http://en.wikipedia.org/wiki/File:Cookie.gif&imgurl=http://upload.wikimedia.org/wikipedia/commons/4/42/Cookie.gif&w=382&h=380&ei=94tHUKG4HebIigKD_4GYAw&zoom=1&iact=hc&vpx=175&vpy=170&dur=259&hovh=224&hovw=225&tx=109&ty=100&sig=103880092138224590058&page=1&tbnh=134&tbnw=135&start=0&ndsp=19&ved=1t:429,r:0,s:0,i:141 so here is a virtual cookie!! :) haha hope that shows up!!

Answer 19

LOL now i want a cookie! anyhow thanks for the help @UnkleRhaukus and @PaxPolaris you are the best!! :)

Answer 20

now i'm hungry....

bye

Answer 21

hahaha yeah... me too! sorry bout that! lol anyways bye now!! see ya on open study some other time then!! :) maybe today! hahaa thanks again! :) i gotta get some food now :)

Answer 22

the other way to wreck a magnet is to heat it

Answer 23

really? that's cool! i never knew that! thanks @UnkleRhaukus :)

Answer 24

@PaxPolaris if u see this later, could you please give @UnkleRhaukus a medal?? I totally forgot to ask you if you could!! Wow!!! my bad!! :) cuz u both helped a ton!! but i could only give one :( thanks!! gotta get food now!! byeee :)
