Fill in only the ovals for numbers 1 through 60 on your answer sheet.  \nCALCULATORS MAY NOT BE USED IN THIS PART OF THE EXAMINATION.  \nIndicate all of your answers to the multiple-choice questions on the answer sheet. No credit will be given for anything written in this exam booklet, but you may use the booklet for notes or scratch work. After you have decided which of the suggested answers is best, completely fill in the corresponding oval on the answer sheet. Give only one answer to each question. If you change an answer, be sure that the previous mark is erased completely. Here is a sample question and answer.  \nSample Question  \nChicago is a  \n(A) state  \n(B) city  \n(C) country  \n(D) continent  \nSample Answer  \n A  C D  \nUse your time effectively, working as quickly as you can without losing accuracy. Do not spend too much time on any one question. Go on to other questions and come back to the ones you have not answered if you have time. It is not expected that everyone will know the answers to all the multiple-choice questions.  \nAbout Guessing  \nMany candidates wonder whether or not to guess the answers to questions about which they are not certain. Multiple-choice scores are based on the number of questions answered correctly. Points are not deducted for incorrect answers, and no points are awarded for unanswered questions. Because points are not deducted for incorrect answers, you are encouraged to answer all multiple-choice questions. On any questions you do not know the answer to, you should eliminate as many choices as you can, and then select the best answer among the remaining choices.  \nPractice Test 1  \n9  \nSection I  \nCHEMISTRY SECTION I  \nTime—1 hour and 30 minutes  \nGO ON TO THE NEXT PAGE.  \n10 | Cracking the AP Chemistry Exam  \nSection I  \nb  \nGO ON TO THE NEXT PAGE.  \nPractice Test 1  \n11  \nSection I  \nGO ON TO THE NEXT PAGE.  \n12 | Cracking the AP Chemistry Exam  \n1.

When some LiCl is dissolved in water, the temperature of the water increases. This means that:  \n(A) the strength of the intermolecular forces between the water molecules is stronger than the bond energy within the LiCl lattice  \n(B) the attraction of the lithium ions to the negative dipoles of the water molecules is weaker than the attraction of the chloride ions to the positive dipoles of the water molecules  \n(C) breaking the bonds between the lithium and  \nchloride ions is an exothermic process  \n(D) the strength of the ion-dipole attractions that are  \nformed exceeds the lattice energy in LiCl  \nUse the following information to answer questions 3-6  \nA student titrates some 1.0 M HCl into 20.0 mL of methylamine (CH3NH2), a weak base which only accepts a single proton.
