Hope this helped!!!
Salt makes the freezing point of water decrease, so it would freeze at a warmer temperature than regular water
Answer:
divergent
Explanation:
Plates move apart at a divergent boundary
∆H for given reaction -847kJ
- As it's negative reaction is exothermic
So
2 mol of Al releases 847KJ heat
4 mol Al releases
∆H=-1694KJ
