1. ¿Cuál es la molalidad de una solución 3.75 M de
ácido sulfúrico (H SO2) con una densidad de 1.23
g
?
mL

Ineed with this also i hope you understand it

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.

Are there any options that could alot..
