We are told hydrochloric acid, when hydrochloric acid, is added to sodium, hydrogen carbonate, or sodium bicarbonate.
00:18
The products are water, sodium chloride, and carbon dioxide gas.
00:36
Okay, so let's take a look here.
00:39
I have, should be balanced, okay, we are balanced.
00:44
What is the percent yield if 10 grams of, sodium bicarbonate reacts with excess hydrochloric acid and 4 .68 grams of carbon dioxide are collected.
01:22
So this is my actual yield.
01:28
This is easy.
01:29
That's going to be a precise yield problem, or a mass mass conversion, strochometric conversion.
01:36
And i'm given 10 grams of sodium, bicarbonate or sodium hydrogen carbonate.
01:46
So let's see here, sodium hydrogen carbonate.
01:50
And i should know this one off the top of my head, but i'm drawing a blank.
01:57
23 plus 48 plus 12 is 82 .998.
02:06
I'm going to go 83 .00.
02:27
Did i did this wrong? it's 84 .01.
02:32
Hang on...
