2. Decide whether each of the following statements is true or false. If false, rewrite it to make it true. a. Entropy of the universe increases in all spontaneous reactions. wo False If entropy is bw enough it con be spontaneous, b. Reactions with a negative free energy change (A-Gº <0) are product-favored and occur with rapid transformation of reactants to products. True c. An exothermic reaction will always be spontaneous. I NO when AH is negative the reaction can...

Determine whether the following statement is true or false: If a reaction is endothermic and entropically favoured, the reaction is always spontaneous. Select one: True False
13. Indicate whether the following statements are true or false. If false, correct the statement so that it is true. a. A change in enthalpy for exothermic chemical reactions is negative. b. An endothermic reaction is one in which enthalpy is absorbed by the system from the surroundings. c. Condensation of water vapor is an example of an endothermic process. d. Heat, q, and enthalpy, AH, are state functions, meaning they depend on the path taken, and q = AH....
Requirement 1. Indicate whether each of the following statements is true or false. For each false statement, explain why it is false. Use Tor F to indicate whether each of the following statements is true or false. Change each false statement into one that is true. 1. A large cash balance is the best evidence of previous profitable operations. 2. Accounts receivable should be classified as a liability. 3. Machinery used in the business should be recorded at replacement cost....
Question 2: Indicate whether each of the following statements is true or false and explain concisely why. 5. The null hypothesis is initially presumed to be true. If we reject it after a hypothesis test, it means we are certain the null hypothesis is false.
State whether the following statements are true or false (4 pts each) If false the statement to make it true AG must be positive for a reaction to be spontaneous Water and copper metal have the same specific heat. Bond breaking is an exothermic process. The best structure is where formal charges are minimized.
