00:00:01.780 --> 00:00:05.580 A:middle L:90%
That's so we're doing question numbers in the aid of
2
00:00:05.580 --> 00:00:09.289 A:middle L:90%
Chapter five in chemistry Central Science to Die Antal either
3
00:00:09.300 --> 00:00:13.380 A:middle L:90%
See, for ages ten and oh, well,
4
00:00:13.519 --> 00:00:16.649 A:middle L:90%
a flammable cos once you surgical anesthetic has it as
5
00:00:17.579 --> 00:00:22.629 A:middle L:90%
as as is shown right here, The complete combustion
6
00:00:22.629 --> 00:00:27.609 A:middle L:90%
of one mole of see for is ten o to
7
00:00:27.620 --> 00:00:31.100 A:middle L:90%
co two and issue A ll yield Delta H minus
8
00:00:31.399 --> 00:00:34.770 A:middle L:90%
two seven twenty seven, twenty eight, twenty,
9
00:00:34.770 --> 00:00:37.049 A:middle L:90%
seven hundred twenty three point seven. Killer Jules,
10
00:00:38.039 --> 00:00:40.490 A:middle L:90%
right, Abounds equation for the combustion of one mole
11
00:00:40.500 --> 00:00:46.009 A:middle L:90%
of O of ah diable Either there. And then
12
00:00:46.009 --> 00:00:47.969 A:middle L:90%
we're going to use the information problem to catch the
13
00:00:47.969 --> 00:00:51.049 A:middle L:90%
Delta H f for diable either. So if we're
14
00:00:51.049 --> 00:00:54.320 A:middle L:90%
dealing with one mall of our settle of our die
15
00:00:54.320 --> 00:00:56.210 A:middle L:90%
, it'LL either there's going to have a one in
16
00:00:56.210 --> 00:00:59.020 A:middle L:90%
front of it comes in and sees a different color
17
00:01:03.240 --> 00:01:07.250 A:middle L:90%
. Killer just emphasized the answer So us. So
18
00:01:07.250 --> 00:01:11.159 A:middle L:90%
we have we have forces over here. We have
19
00:01:11.159 --> 00:01:11.290 A:middle L:90%
one over here. So we have two out of
20
00:01:11.290 --> 00:01:17.560 A:middle L:90%
four over here. No, we have five Hydra
21
00:01:17.769 --> 00:01:19.129 A:middle L:90%
. We have ten agents here to overhears You have
22
00:01:19.129 --> 00:01:22.219 A:middle L:90%
about five, because five times, Suze, equal
23
00:01:22.219 --> 00:01:26.819 A:middle L:90%
to ten. Now we have. Oxygen's on the
24
00:01:26.819 --> 00:01:29.819 A:middle L:90%
right. We have eight and we have five over
25
00:01:29.819 --> 00:01:30.549 A:middle L:90%
here. So we have thirteen on the right.
26
00:01:33.140 --> 00:01:34.650 A:middle L:90%
We have three and we have one of we have
27
00:01:34.650 --> 00:01:37.730 A:middle L:90%
to. Here we have one. Here's that story
28
00:01:37.730 --> 00:01:40.230 A:middle L:90%
on the left. So we're going to put this
29
00:01:40.230 --> 00:01:42.180 A:middle L:90%
one aside, so we need twelve more oxygen's.
30
00:01:42.189 --> 00:01:44.680 A:middle L:90%
So we're going to go to six in front of
31
00:01:44.680 --> 00:01:51.189 A:middle L:90%
here here, and that's going to be our balance
32
00:01:51.189 --> 00:01:53.819 A:middle L:90%
question for one bowl of Di Ato either. Next
33
00:01:53.819 --> 00:01:57.140 A:middle L:90%
we're gonna find the Delta H Value. So remember
34
00:01:57.140 --> 00:01:59.590 A:middle L:90%
the music has little dealt h reaction is you could
35
00:01:59.599 --> 00:02:01.230 A:middle L:90%
tell teacher products might still teach. React things so
36
00:02:01.230 --> 00:02:07.409 A:middle L:90%
modest, too. Seven, two three. In
37
00:02:07.409 --> 00:02:09.199 A:middle L:90%
fact, let's just send it up like this.
38
00:02:10.550 --> 00:02:15.370 A:middle L:90%
It'LL make it less confusing. Remember, this is
39
00:02:15.370 --> 00:02:34.360 A:middle L:90%
Hess's law. So now we're going to switch things
40
00:02:34.360 --> 00:02:39.300 A:middle L:90%
around. So Delta H R. Is equal to
41
00:02:39.300 --> 00:03:00.060 A:middle L:90%
Delta H P minus delta H reaction. So the
42
00:03:00.069 --> 00:03:05.560 A:middle L:90%
member since auctions and elements standard states that's going Teo
43
00:03:05.819 --> 00:03:08.710 A:middle L:90%
, give us eight at age. Those ages equal
44
00:03:08.710 --> 00:03:13.909 A:middle L:90%
zero killer Just Ramon. So our only reacting is
45
00:03:13.909 --> 00:03:16.229 A:middle L:90%
going to be our diet a liter, so don't
46
00:03:19.219 --> 00:03:24.740 A:middle L:90%
so the age of of iron diet either is going
47
00:03:24.740 --> 00:03:28.729 A:middle L:90%
to equal to some of the products. Manistee minus
48
00:03:28.729 --> 00:03:32.539 A:middle L:90%
the reaction. So we got five times negative to
49
00:03:32.539 --> 00:03:40.360 A:middle L:90%
eighty five point eight plus four times three nine minus
50
00:03:40.360 --> 00:03:57.229 A:middle L:90%
three. Ninety three point five five minus negative to
51
00:03:57.370 --> 00:04:04.385 A:middle L:90%
seven. Three. Yeah, minus two seven two
52
00:04:04.776 --> 00:04:09.725 A:middle L:90%
, three point seven. So we're going to put
53
00:04:09.725 --> 00:04:46.855 A:middle L:90%
everything into a calculator. Tell that to H F
54
00:04:46.855 --> 00:04:49.685 A:middle L:90%
. For this reaction is going to be minus two
55
00:04:49.776 --> 00:04:59.266 A:middle L:90%
seventy nine point point three. Kill a Jules Promote
56
00:05:10.776 --> 00:05:14.406 A:middle L:90%
knows that's going to be deducted. Age of information
57
00:05:14.415 --> 00:05:15.985 A:middle L:90%
for our diet a liter.
