Answer:
It is a combustion reaction
Explanation:
Answer: when concentrations of acid and base are same, pH = pKa
PH = 12.38 pOH = 1.62
Explanation: pKa= -log(Ka)= 12.38. PH + pOH = 14.00
I believe the correct answer from the choices listed above is the first option. During a physical change, m<span>olecules can move more rapidly and freely and change states.
