K3PO4 + Al(NO3)3 + 3KNO, + AIPOA What is the mass in grams of kno3 that is produced when 2.04 moles of k3po4 react

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?

In a heat engine of 1000 j of heat enters the system and the piston does 500 j of work what is the final internal energy of the system if the inital energy was 2000 j we have to do all of these down here 1)write the equation 2)list out your know variables 3)plug the numbers into the equations 4)solve 5)write your solution statemtn that includes inital energuy and final energuy added

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
