i believe it would be chemical
Answer:
[H₃O⁺] = 7.08×10⁻⁹ M
Explanation:
pH = - log [H₃O⁺]
[H₃O⁺] = 10^⁻pH
Therefore, [H₃O⁺] = 10⁻⁸¨¹⁵
[H₃O⁺] = 7.08×10⁻⁹ M
The reddish brown powder consist of copper ions(when mixed in H2O ) which conduct electricity.
Answer:
im pretty sure they heat up
Explanation:
as they use energy to go from solid to liquid to gas, they need heat to do so as they have a melting and boiling point
