Heats of Reaction
- *Aim According to Hess’s law, the heat of reaction of the one reaction should be equal to the sum of the heats of reaction for the other two. Measure the heat released by 3 reactions by using a Styrofoam-cup to than calculate for the heat of reaction, ΔH, fo...

THE TOPOLOGY FILMS PROJECT
- This film is about the forming curve in the plane. You can think the curve with the pass with the moving point. But we will acquit the curve satisfied certain condition. First, we only consider closed curves. That is closed with the moving point return to th...

Wavelength Lab
- In this experiment, I don’t think there is not so much error. The reason for this is because we can only make an error in the measurement. The room temperature, humidity may cause some changes but I think in this experiment, we don’t have much effect by thes...

Investin Sequence
- From the question above, we can see that for n = 1, we will get 1 x 1! by the equation. And for n = 2, we have 2 x 2! and identically, we have 3 x 3!, when n = 3. There is a simple pattern. So, we can understand that the n x n! is the formula for the nth ter...
