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.

(1 point) Note: The notation from this problem is from Understanding Cryptography by Paar and Pelzl. We conduct a known-plaintext attack against an LFSR. Through trial and error we have determined that the number of states is m = = 4. The plaintext given by 11101101 = x0x1x2X3 X4 X5 X6 X 7 when encrypted by the LFSR produced the ciphertext 10000000 = YoY1Y2Y3Y3Y5Y6Y7. What are the tap bits of the LFSR? Please enter your answer as unspaced binary digits (e.g. 0101 to represent P3 = 0, P2 = 1,p1 = 0, po = 1).
