An ideal coffee-cup calorimeter: no heat escapes and the cup itself absorbs nothing. Solutions are treated as water (1.00 g/mL, c = 4.184 J/(g·°C)). Time runs much faster than a real experiment, and particle speeds are exaggerated so you can see them change. The numbers follow q = mcΔT exactly.
The picture updates with the answer you type. The worked solution shows each unit cancelling (struck through in red) and each sum built line by line.
Your jobFlip and multiply the given equations, then add them to the sum, so that everything cancels down to the target. Drag a card by its handle into the sum, or press its Add button. Flipping changes the sign of ΔH; multiplying multiplies ΔH.
