So for this question, we'll look at each reaction individually.
00:06
The first one, into gas, it's two in gas.
00:10
This reaction is endothermic.
00:12
The bonds are broken down to form new individual bonds.
00:15
So this requires more energy to break down the compounds.
00:18
So it's an endothermic reaction.
00:21
The second one is h2o liquid into h2 solid.
00:25
So when the liquid water changes to ice, like new bonds are formed, because liquid, the bonds and liquids are very weak.
00:32
So when they form solid bond, it's a stronger bond in the product size, so it releases energy.
00:38
Remember, when bonds are broken, you put its endothermic reaction to break the bonds, and when they form against it's an exothera reaction...
