Consider the reaction 2A + 3B ⟶3C + 2D. The standard enthalpy of formation for A, B, C and D are -79.8, 49.2, -145.8, and -87.4, respectively in kJ / mol. What is the standard enthalpy change for the reaction in kJ/mol?

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

um i think it might be a car?

listen, you cant how young you were.

"you didn't chose the stud life. the stud life chose you."
