you know what enthalpy is?

Answer 3

Answer 6

yea

heat = energy so when the enthalpy changes when heat (energy) is released or absorbed

Answer 8

whoa. mind blown.

Answer 9

so true. & what about this one?When concentrated sulfuric acid is added to water in a beaker, the beaker gets very warm. The temperature change indicates an exothermic process has occurred.

Answer 10

Thats true too right?

Answer 11

warmth is an indication of release of energy.
look up the definition for exothermic and endothermic :)

Answer 12

am I right? @abb0t
