Answer:
option A= pH = 0.1
Explanation:
Given data:
Concentration of H₃O⁺ = 0.8 M
pH = ?
Solution:
pH = -log [H₃O⁺] H₃O⁺ = H⁺
pH = -log [0.8]
pH = - (-0.097)
pH = + 0.1
<span>The melting of ice is an event which is endothermic. Endothermic is the process when heat is transfer from the environment to the object.
