Answer:
Yes! It's because of like freezing and or solidification. It's the phase transition in which a liquid turns into a solid. It's when the temperature is lowered to or below a type of freezing point.
Explanation:
Answer:
i) Use of wrong Indicator in acid base titration.
ii) Addition of chemicals with improper sequence.
iii) Wrong technique used during chemical reaction.
Answer:
neutrons are part of atom with no charge
∆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
