and would make it endothermic???
anonymous
  • anonymous
because the magnesium is becoming warmer and will eventually burn completely???
nincompoop
  • nincompoop
what does endothermic mean?
anonymous
  • anonymous
when heat is formed and energy is created?
nincompoop
  • nincompoop
thinking that if it is an endothermic, what are the consequences?

I must be way off. I apologize. I thought I understaood it.

http://www.youtube.com/watch?v=5RJLvQXce4A watch this short video, which is an example of an endothermic reaction

would the heat be absorbed as a consequence/

Okay I will watch it. Thank you.

It was cold instead of hot (endothermic) but I don't understand. In a previous lesson of mine, it said that if we warm ourselves with an electric blanket, it would be endothermal. This would mean heat, not cold.

* endothermic (not endothermal)

this guy is really good at making things easy to understand http://www.youtube.com/watch?v=8m_FCe5aCqY so you are correct, endothermic means it absorbs heat (endo - within or in) exothermic (exo - outside) so when you see a +△H it means it is has absorbed heat and -△H means it has released heat
anonymous
  • anonymous
So I had it backwards. It would be negative (releasing heat) - B
anonymous
  • anonymous
because the magnesium would in fact be releasing heat as it burns ????
nincompoop
  • nincompoop
so what do you think is the answer?
nincompoop
  • nincompoop
endothermic = absorbs = +△H
anonymous
  • anonymous
so release would be -△H ??
nincompoop
  • nincompoop
yeahhhh when you take out money (think of it as heat), you are deducting it from your pocket

  • anonymous
That makes sense- thank you so much
