Thank you so much. My lab instructor left us with this, something I've never seen before and went "Given the units. Solve for the heat absorbed by the calorimeter"
Excellent example. I am a retired high high school teacher and did an EXCELLENT tutorial that any student having difficulty with this concept would understand!
You really do have the gift of teaching! Your great attitude and reassurance makes for the perfect combination. You taught this wonderfully, Thank you:)
omg. i have been searching the internet on how can i find the amount of heat released by a reaction wherein the two reactants have different initial temperature. i can only see examples that has both reactants have the same initial temperature :((
Hi Amel, I only know of these 2 methods: 1. 2 reactants have the same initial temperature and when mixed they undergo a chemical reaction. On my playlist, thermodynamics, select solutions part 2. Or 2. Two substances have different initial temperatures and when mixed there is a transfer of energy but no chemical reaction. That is like this video. I have not seen a problem with both different initial temperatures and upon mixing undergoes a chemical reaction. Ask your professor for help with that problem if this is the case. ( Make sure your problem with different initial temperatures will indeed undergo a chemical reaction.) In the lab, if mixing 2 solutions that undergo a chemical reaction, let both solutions sit at room temperature so they have the same initial temperature before mixing. I hope that helps!!
