If 8 amperes of current is pushed through a 2 2 resistor by a battery. What is the voltage? (Formula V=I x R)
140 Volts
16 Volts
300 Volts
8 Volts

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.
