Answer:
The temperature of the solute/solvent without any external effect would decrease.
Explanation:
As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.
In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.
Those are types of water on a pH scale 7.0 and above are alkili water and anything under that is acidic
Answer:
2.65939942411 ( Round if needed)
Explanation:
The reason it is this is because, one mole of magnesium weighs 24.31 grams. So if you know that, then you would do 64.65 grams divided by 24.31 grams to get you a final amount of 2.65939942411 moles.
1. 80 Kj
2. 120-80= 40 Kj
3. 120-20= 100Kj
4. 20-80= -60Kj
5. +60 Kj
6. Exothermic because 4 is negative
Water vapor is important to the weather because it creates clouds. Without clouds there would be no rain, and without rain there wouldn't be as much water now as there was 100 years ago because it wouldn't recycle. Water Vapor is very important to the weather and life as we know it.
