Alfred Wegener came up with the idea
Hello,
Here are your answers:
The proper answers to your questions are....
1. "Chemical bond energy is converted to kinetic energy"...... which causes it to release energy around its surroundings!
2. "Endothermic reactions"...... Endothermic reactions are the things that absorb the energy!
If you need anymore help feel free to ask me!
Hope this helps!
Answer: The final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
Explanation:
According to the dilution law,
where,
= molarity of stock 
solution = 2.5 M
= volume of stock solution = 5 ml
= molarity of diluted solution = ?
= volume of diluted solution = 750 ml
Putting in the values we get:
Therefore the final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
It is endothermic and the ∆H = +393.5 kJ.
