I need a device that minimizes heat transfer and how it minimizes heat transfer. ill give brainliest to the best answer.

Hydrogen Sulfide decomposes according to the following reaction, for which Kc=9.3 x 10^-8 at 400 degrees Celsius. 2 H2S (g) ⇄ 2 H2 (g) + S2 (g) If 0.47 moles of H2S are placed in a 3.0 L container, and the system is allowed to reach equilibrium.

Q5.6. if calcium ions, each of which has a charge of + 2 (ca2+), moved out of a neuron, and no other ions were moving, what would be true?

Calculate the moles of new H₂ O₂ using the balanced formula below and the average moles of KMnO₄ from calculation #2. The average moles of KMnO₄ is 0.90mol. 2KMnO₄ + 5H₂O₂ + 3H₂SO₄ → K₂SO₄ + 2MnSO₄ + 8H₂O + 5O₂ Edit: I got 2.
