Hi there.
00:03
In this question, we have some statements about exothermic and endothermic reactions, and we have some blanks to fill in in these statements.
00:11
So let's start off with the first, call it a paragraph here.
00:15
It is about exothermic reactions.
00:18
And in the word exothermic, we see exo.
00:21
Just like exit, that means out of.
00:25
So in an exothermic reaction, heat is released.
00:37
So our first blank there is released, because exothermic.
00:40
Means that heat comes out of the reaction.
00:43
It is released.
00:45
Since it's released, it appears on the product side.
00:56
So it appears as a product because it's something that's produced.
01:01
It is given off.
01:02
It's something that's produced.
01:04
So it is a product.
01:05
So it appears on the product side of the reaction.
01:09
And the test tube will feel, since energy is being given off, heat is being released, we will feel that heat and the test tube will feel warmer.
01:26
All right.
01:27
So if we want to show an exothermic reaction as a chemical reaction, we will have the reactants producing the products plus heat.
01:47
So heat is on the product side.
01:50
It is being released.
01:51
It is being given off.
01:52
It is a product...
