<em>Sample</em><em> </em><em>A</em><em> </em><em>-</em>
Sample B -
In an endothermic reaction, “delta H” is always positive, since the system is absorbing heat from its surroundings, not releasing into the surroundings like in an exothermic reaction where the delta H is always negative.
So our endothermic reactions would be the first (484kJ) and the last (92kJ).
Answer:
Because it might be reactive or may lose its property in liquid form..
Answer:
a or b
Explanation:
because those are the most likely to be true
now it gives you two options so i thinks it might be B but you could choose A you got two options choose wisely
I think it's physical change
