Given 635.4 mL of a 7.5 M HNO, acid how many moles would I have? ​

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.

It must be measured in k.hope my answer is to you : )
