Electrolysis Compounds are broken down into simpler substances using electricity. In order to work, ions must be free to move so need to be dissolved in water or melted Electrolyte The liquid that conducts electricity How does electrolysis work There is a flow of electrons that are taken away from the positive electrode and given to other ions at the negative electrode. As ions gain or lose electrons they become atoms/molecules and are then released. Positively charged ions move to negativ...

CHEM 103 MODULE 1 EXAM 2023/2024 MODULE 1 EXAM Question 1 Click this link to access the Periodic Table. This may be helpful throughout the exam. 1. Convert 845.3 to exponential form and explain your answer. 2. Convert 3.21 x 10-5 to ordinary form and explain your answer. 1. Convert 845.3 = larger than 1 = positive exponent, move decimal 2 places = 8.453 x 102 2. Convert 3.21 x 10-5 = negative exponent = smaller than 1, move decimal 5 places = 0.0000321 Question 2 Click this link to...
