2. 0.50 moles of H2SO4
Determine the number of grams in the quantity?

U whay do you need with?

Iwould you figure it out but you don't have a picture or in your question as to what the physical property you're looking for is

The answer is b because a,c,and d are opinons

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.
