5:10 Question 4 of 15 .5G Which of the following describes the entropy change in the given reaction? 2 Cl₂O(g) → 2 Cl₂(g) + 7 O₂(g) Submit A) The entropy change is negative because a larger molecule (Cl₂O₂) is converted into two smaller molecules (Cl₂ and O₂). B) The entropy change is zero because the reactants and products are all gases. C) The entropy change cannot be determined because the temperature is not specified. D) The entropy change is negative because there are more moles of products than reactants. Tap here or pull up for additional resources E) The entropy change is positive because there are more moles of products than reactants.

4. You are drawing an octahedron (6 vertices, 8 triangles) and are considering whether to use an indexed polygon representation or a triangle-based representation. Assuming coordinates for vertices are given as 4 floatin point values and the indexes for polygons are given as 2-byte unsigned short values, how many bytes will each storage option take? Which is smaller? Note: you do not need to give either representation-only determine the amount of storage the representation would require.
