Step 1: Balance the Aluminum (Al) atoms. There is 1 Al atom on the left in Al(OH)_3 and 1 Al atom on the right in AlPO_4. Aluminum is balanced. Step 2: Balance the Phosphorus (P) atoms. There is 1 P atom on the left in H_3PO_4 and 1 P atom on the right in AlPO_4. Phosphorus is balanced. Step 3: Balance the Hydrogen (H) atoms. On the left, there are 3 H atoms in Al(OH)_3 and 3 H atoms in H_3PO_4, totaling 3 + 3 = 6 H atoms. On the right, there are 2 H atoms in H_2O. To balance the 6 H atoms on the left, we need 3 molecules of H_2O on the right (3 × 2 = 6). Al(OH)_3 + H_3PO_4 → AlPO_4 + 3H_2O Step 4: Balance the Oxygen (O) atoms. On the left, there are 3 O atoms in Al(OH)_3 and 4 O atoms in H_3PO_4, totaling 3 + 4 = 7 O atoms. On the right, there are 4 O atoms in AlPO_4 and 3 × 1 = 3 O atoms in 3H_2O, totaling 4 + 3 = 7 O atoms. Oxygen is balanced. The balanced equation is: Al(OH)_3 + H_3PO_4 → AlPO_4 + 3H_2O a) The specific branch of Chemistry that deals with identifying the components and purity of substances, such as medicines, is Analytical Chemistry. b) The systematic nature of Chemistry provides standardized analytical techniques (e.g., chromatography, spectroscopy) to determine the exact chemical composition and purity of the medicine. By comparing the results from the suspected medicine to the known chemical profile of genuine Amoxicillin, the investigator can objectively identify the presence of impurities like chalk and the absence of the active drug. This reproducible and verifiable evidence can then be presented in court to prove the medicine is counterfeit. a) • Prescription: This is the official instruction from a healthcare professional detailing the specific medicine, its strength, and the exact amount to be taken per dose (e.g., 5ml) along with frequency and duration. • Dosage: This refers to the actual quantity of medicine administered to the patient at one time. In this scenario, the prescription indicated a dosage of 5ml, but the patient misread the label and took a triple dose, resulting in an actual dosage of 15ml. The error was in the patient taking an incorrect dosage, deviating from the prescribed amount. 3 done, 2 left today. You're making progress.
