the name of this lab is the types of
chemical reactions lab the purpose of
this lab is to use different types of
reactions to predict reaction products
for our hypothesis we're gonna put that
in your data table so we'll get to that
in a minute so here are the materials
and then when you turn the page you're
going to put in the first part of your
procedure and then on the next page
you'll put the second part of your
procedure so you can go ahead and put
those on to separate pages so now I want
you to put your data table and you're
going to fold it in half so you can glue
or tape it into one page of your lab
notebook that way when we open it up we
can see the full data table so when you
open up your data table you're gonna see
several columns in the first column
you're going to see your type of
reaction the second has your reactants
the third column is where you're gonna
fill in your hypothesis and you're gonna
write the formulas for the chemical reor
the formulas for what you think the
products will be based on that
particular type of reaction the rest of
your data table is going to be used for
your observations during the lab and
then the last column will be for your
actual results which I will give you at
the end of this lab video so in the
first part of part 1 we're going to be
burning magnesium
now I'm going to put it on the watch
glass and then there will be a picture
of what that product looks like
in the second part of part 1 we're gonna
be burning a piece of copper so here's
my copper
and I'm gonna hold it in the flame
so as I'm looking at it I can see that
the copper is changing color and I will
put a picture of this brick after this
video clip so you can see what it looks
like after it's been in the flame
so in part two we are looking at sodium
carbonate being heated in a test-tube so
here's what it looks like to start with
and then we are going to heat it for
about two minutes you should be making
observations about what's happening to
the salad and what's happening inside of
the test tube
so we're at about one minute
okay so I think we're at about two
minutes so I'm going to go ahead and do
the wood splint test splint on fire
and there we go in the first part of
part three we are going to mix ilver
nitrate and a piece of solid copper so
here's our piece of solid copper I'm
gonna put that in the test tube here's
my silver nitrate
and now it's supposed to sit for five to
ten minutes so I will include a couple
of pictures that show the time lapse
between now and when this reaction is
finished
in the second part of part three we are
going to cover zinc with hydrochloric
acid so here's what the zinc looks like
I'm gonna put that in a test tube and
then I'm going to cover it with three
molar hydrochloric acid
okay and here's what's happening in that
reaction
in the first part of part 4 we're gonna
mix calcium chloride solution and silver
nitrate solution so here's my silver
nitrate solution and here is my calcium
chloride solution so they're both clear
to begin with you know put my silver
nitrate in my test tube
and then I'm gonna add my calcium
chloride solution
and so here's what that reaction looks
like remember those two liquids those
two solutions were clear to begin with I
can kind of see a solid forming on the
bottom if I were to let that sit I will
put a picture in after this video as to
what this looks like after it sits for
several minutes
in the second part of part 4 I'm gonna
mix my salad sodium carbonate so that's
what that looks like that's the white
powder in the test tube with some three
molar hydrochloric acid so I'm going to
add the acid to my test tube
one day got all fizzy and I could hear
it I don't know if you can if I feel the
bottom the bottom of that is very warm
so I saw it get fizzy and the bottoms
warm and you could even hear it bubbling
in part five I'm gonna look at the
combustion of isopropyl alcohol so I'm
going to put 10 drops of isopropyl
alcohol on my watch glass
and then I'm gonna light it and while
it's burning I'm gonna hold a beaker up
here so I can see if I can see water
condense on the bottom of the bigger
so I see maybe a little bit of water
condensed on this side of the beaker
it's just a little bit foggy and so I
see just a little bit of water over on
this side of the beaker so here are the
accepted results for our different
reactions so for our first synthesis
reaction between magnesium and oxygen we
get magnesium oxide as our product for
our second synthesis reaction between
copper and oxygen we get copper to oxide
as our product for a decomposition
reaction the two of sodium bicarbonate
we get sodium carbonate water and carbon
dioxide as our products for our first
single replacement reaction between
silver nitrate and copper we get silver
and copper to nitrate as our two
products for our second single
replacement reaction between zinc and
hydrochloric acid we get zinc chloride
and hydrogen gas as our products for our
first double replacement reaction
between silver nitrate and calcium
chloride we get silver chloride and
calcium nitrate as our two products for
our second double replacement reaction
between sodium carbonate and
hydrochloric acid we get sodium chloride
water and carbon dioxide as our products
for our combustion reaction we get
carbon dioxide and water as our two
products
