  • 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...

  • 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...

  • 寒冷圏の科学
  • 1.湖や池の氷(真水氷)と海氷の違いは何か?それぞれの生成の仕方を説明せよ。 真水は0℃で凍るが、海水は−1.8℃にならないと凍らない。そして真水は0℃になればなったところから凍るが海水は上から下まで−1.8℃にならないと凍らない。そのため海が凍る際には塩分の薄いとこ...
