milk has a pH of 6.0 and household ammonia has a pH of 12.0. How much more acidic is milk than ammonia

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

Ahigh energy (high speed) particle (alpha or beta or neutron) are shot at the target;
