sorts of things can happen in a chemical reaction Sometimes
- 00:28
we makes a couple of things together and nothing happens
- 00:31
And sometimes we makes a couple of things together and
- 00:33
well they go Boom Big boom Right Well these types
- 00:38
of reactions when two substances give off heat are called
- 00:42
exo thermic reactions You are correct Answer option is okay
- 00:47
Xo thermic that comes from a couple of ancient greek
- 00:52
words The root word acts means out and ther mus
- 00:56
is what your uncle in wisconsin uses Keep his coffee
- 00:59

thermic means well he goes out and endo thermic reaction
- 01:08
is just the opposite in an endo thermic reaction Heat
- 01:12
is absorbed when the chemicals react Now cnd displacement and
- 01:17
replacement reactions are essentially the same thing And these types

- 01:30
people well when the chemicals react one element moves out
- 01:34
of one compound and into the other Let's say we
- 01:37
start with substance a and we mix it with substance
- 01:40
B c well in a replacement or displacement reaction After
- 01:44
the reaction we'd be left with two new chemicals so
- 01:47
we'd start with a nbc and end up with b
- 01:50
and a c Remembering a little ancient greek can really
- 01:54
help make sense in the world and those old dudes
- 01:57
really had a keen sense of fashion We enjoy wearing
